Owning a riding mower means you can finish the whole lawn in one session, and the best tow behind aerators for riding mowers extend that logic to soil work. A tow behind aerator is a wheeled implement you hitch to a tractor, zero-turn or ATV so its rotating drum of hollow spoons pulls 2.5 to 3 inch plugs of soil out of the turf. That removes the compaction that starves grass roots of air and water, and it lets seed, water and fertilizer reach the root zone instead of sliding off the surface.
The catch is that a tow behind aerator is a machine, not a wand. It only bites when the weight tray is loaded, it works in real plugs rather than punctures, and it takes a couple of passes to matter. Owners on r/lawncare say it plainly: they work, but not as well as a push or riding aerator, and you need a lot of weight on the tray to get them deep enough. Another r/lawncare user runs three cinder blocks on the tray of a small John Deere E100 and says it works fine in moist soil.
We spent weeks screening twelve tow behind aerators against the questions riding mower owners actually ask: will my tractor pull it, how much ballast do I need, does it leave a mess, and is it worth owning instead of renting. The picks below cover everything from a 36 inch spike unit for a quarter-acre lot to a 48 inch plug machine for a heavy clay yard.

1. Agri-Fab 48 Inch Tow Behind Plug Aerator – Best Overall for Large Yards
Agri-Fab 48 In Tow Behind Lawn Plug Aerator with 32 Galvanized Knives and Universal Hitch
32 galvanized knives
Plugs up to 3 in deep
175 lb weight tray
94 lb unit
Universal hitch
Pros
- 32 self-sharpening galvanized knives
- Pulls plugs up to 3 inches deep
- 175 lb tray accepts heavy ballast
- Cantilever transport handle raises from the tractor seat
- Flat-free tires roll over uneven ground
Cons
- 48 inch frame is wide around trees and beds
- Cores must be broken up and dispersed afterward
This is the machine most riding mower owners end up with, and the review numbers back it up with more than 2400 ratings behind it. The 32 galvanized self-sharpening knives pull cores up to 3 inches deep, tied for the deepest plug depth here, and the 175 lb tray is the largest capacity of the twelve aerators here.
Weighing 94 pounds empty, it is a serious tow. The cantilever transport handle is the detail riding mower owners care about most, because it lifts and drops the drum from the seat rather than forcing you to dismount at every driveway.
What surprised us was how well it tracks a straight line across uneven ground. The 32-knife drum is self-sharpening, so it keeps cutting into hardened soil instead of polishing smooth after a season, and the flat-free tires never need air checks on the way to the far corner of the property.
The width is the honest drawback. At 48 inches the drum is the widest working width of anything here, so end turns around ornamental beds and shrub borders take planning, and the unit measures 35 by 60 by 36 inches in its shipping footprint.
Who this aerator suits
If you have an acre or more of compacted lawn, a heavy clay yard, or a new-build site where nobody ever walked the ground, this is the strongest choice. The 175 lb tray also means you can add enough cinder blocks to make the drum bite on soil that a lighter unit would skate over.
Where it falls short
Owners with heavily planted yards will find the 48 inch drum awkward, and the cores it leaves need to dry before you can break them down. Nobody using it wants to aerate a bed of perennials. If your space is tight, the 40 inch models give up a little coverage and buy back a lot of maneuverability.
2. Agri-Fab 40 Inch Tow Behind Plug Aerator – Best Value Plug Aerator
Agri-Fab 40 In Tow Behind Lawn Plug Aerator with 24 Galvanized Coring Knives and Universal Hitch
40 in working width
24 coring knives
10 x 3 in pneumatic tires
Folding transport handle
Pros
- 24 sharpened galvanized coring knives
- 40 inch working width covers ground quickly
- Large 10 x 3 inch pneumatic tires roll over varied terrain
- Single lever folds down for compact storage
- 73.8 lb unit is manageable for its size
Cons
- Needs adequate soil moisture to core properly
- Pneumatic tires need periodic pressure checks
This is the balanced pick: 40 inches of working width, 24 galvanized coring knives, and a unit that weighs 73.8 pounds rather than nearly 100. It is the version of the Agri-Fab plug aerator that most suburban riding mower owners should be looking at.
The difference from a straight spike unit is everything. Coring knives lift a plug out and leave a hole that stays open, which is what actually relieves compaction. Spikes punch a slit that closes again by the next morning.
Two details set it apart in daily use. The 10 by 3 inch pneumatic tires roll much more smoothly across a rough yard than flat-free rubber, and the single lever transport handle folds flat, so the aerator takes up far less space in a garage over winter than a rigid-frame model.
Owners consistently note one thing: this machine wants moisture. On dry, dusty soil the coring knives skate, and on very loose ground the plugs sit on top rather than breaking apart. Lightly watering the lawn a day ahead makes a visible difference in how cleanly it cores.
Who this aerator suits
It fits a quarter-acre to half-acre suburban lot attached to a mid-size lawn tractor, and the fold-down handle makes it the easier of the two Agri-Fab plug aerators here to store. Owners who overseed in early fall can aerate and then spread in the same afternoon.
Where it falls short
Pneumatic tires are a maintenance item the flat-free models do not have, and the weight tray is smaller than the 48 inch Agri-Fab. If your soil is heavy clay and your tray rating matters more than tire comfort, the bigger machine is the stronger buy.
3. Agri-Fab 40 Inch Tow Behind Spike Aerator – Best for Spike Aeration Without Mess
Agri-Fab 45-0544 40 inch Tow Behind Spike Aerator for Aerating Lawns; 10 Galvanized Steel Spike Disks, Universal Hitch, Black
10 galvanized spike disks
100 lb weight tray
Folding hitch
37.3 lb frame
Pros
- No soil cores to rake up afterward
- 10 galvanized steel spike disks perforate evenly
- 100 lb weight tray for harder soil
- Folding hitch simplifies off-season storage
- Light 37.3 lb frame is easy to handle
Cons
- Shallower than core plug aeration
- Spikes can bend against rocks or buried objects
If the thought of cores scattered across your lawn bothers you, this is the machine that removes the problem entirely. Ten galvanized spike disks perforate the soil and leave no plugs, which makes cleanup a non-issue and keeps the whole job manageable in a single session.
At 37.3 pounds it is the lightest frame in this roundup, and the folding hitch collapses for storage. It is made in the USA and carries a limited warranty from the manufacturer.
Spike aeration is not the same as coring, and buyers should know the trade. The spikes open channels and relieve surface compaction, but the punctures close back up, so the effect is shallower and less durable than a 3 inch core. The 100 lb tray tells you how much ballast to add when the soil hardens.
Owners also flag the one real failure mode: rocks. Strike a spike disk against a buried stone or a root wad and galvanized spikes can bend, so a quick walk with a probe before you start pays for itself on a rough yard.
Who this aerator suits
This suits owners doing monthly maintenance passes, overseeding a thin lawn, or working a yard where fallen leaves and pet mess mean extra raking. It also suits anyone whose riding mower does double duty and who wants aeration that leaves the lawn presentable the moment the pass ends.
Where it falls short
If your problem is deep compaction in clay, a spike aerator treats the surface and leaves the real issue alone. Pick a core plug machine instead. On a large property, the 40 inch spike drum also pulls fewer holes per pass than a 32-knife plug drum.
4. Brinly 40 Inch Tow Behind Plug Aerator – Best All-Steel Build with Rotating Tine Sections
Brinly Tow Behind Plug Aerator with Universal Hitch, 40″ – Flat Black
24 heat-treated spoons
3 in plug depth
150 lb enclosed tray
63.9 lb unit
Single-pin hitch
Pros
- Heat-treated 16-gauge spoons stay sharp
- Plugs pull up to 3 inches deep
- Fully enclosed 150 lb tray
- Three independently rotating tine sections ease turns
- 10 inch semi-pneumatic turf tread tires
Cons
- Heavier duty than the spike units in this group
- All-steel build is heavy to reposition by hand
The Brinly 40 inch plug aerator is a careful, well-built machine, and its 4.4 average comes from close to a thousand reviews. Twenty-four heat-treated 16-gauge spoons pull plugs up to 3 inches deep, and the narrowed spoon design with sharpened ends needs less ballast to get there than most competing drums.
At 63.9 pounds it is lighter than the Agri-Fab 48 inch machine despite the all-steel construction, and the fully enclosed tray is rated for 150 pounds of any ballast material. The universal single-pin hitch attaches to lawn tractors, most zero-turns and ATVs.
The detail that matters most day to day is the three independently rotating welded tine sections. While the frame turns, the sections keep spinning, which is what keeps end turns and 180 degree pivot points from tearing turf into bare patches. Reviewers mention this specifically when describing how the machine handles uneven ground.
The single transport lever engages the 10 inch semi-pneumatic rubber tread tires so you can cross driveways and paths without dragging cores across concrete. There are no flat wheels to replace, which the manufacturer calls out as a durability decision.
Who this aerator suits
It suits owners working a larger lot where the rotating tine sections and the 150 lb tray pay off. The three independent sections handle tight end turns, sloped ground and mixed soil better than the alternatives here.
Where it falls short
It is built to a heavier standard than every spike aerator here, so a small yard with loose soil may not need it. The all-steel frame is also heavier to drag by hand, which matters if you want to position it without a tractor attached.
5. Brinly 40 Inch Tow Behind Spike Aerator – Best for Monthly Maintenance Passes
Brinly SAT2-40BH-P Tow Behind Spike Aerator with Transport Wheels, 40″ – Hammered Black
11 tine stars with 12 tips
2 in penetration
150 lb tray
2 year warranty
Turf-tread transport wheels
Pros
- 132 spike tips on 11 tine stars
- 3-D galvanized tines resist rust and bending
- Rigid 150 lb weight tray
- Turf-tread transport wheels avoid flat tires
- 5/8 inch solid steel axle with nylon spacers
Cons
- Assembly takes roughly 1 to 1.5 hours
- Manual has conflicting diagrams
- Some boxes arrived with too few axle spacers
This one is built for routine work. Eleven tine stars with 8 inch diameters and 12 spike tips each give it 132 individual tips, and owners report tine paths visible through the grass without lifting the turf.
The patent-pending 3-D galvanized tines are the engineering story here. They are built for twice the strength of a standard spike and resist both rust and bending in compacted soil, on an extra-strength double tow bar with a 5/8 inch solid steel axle.
One owner reported driving the tines a full inch into heavy clay soil with two and a half cinder blocks of ballast, and called the purchase well worth it. The rigid 150 lb tray accepts a serious load, and the turf-tread transport wheels sidestep the flat tire problem entirely.
Assembly is the weak point, and buyers should plan for it. Expect an hour to an hour and a half with a manual that has conflicting diagrams and mislabeled bolts, and check the axle spacer count before you start because a few units arrived short.
Who this aerator suits
A good fit for overseeding prep and monthly maintenance on a lawn that stays in good shape rather than one that needs rescue. The tine pattern is dense enough to feel like real work, and it leaves nothing to clean up when you finish.
Where it falls short
Two inch penetration is well short of a 3 inch core, and the assembly experience is longer than most. Owners also warn that the tines are extremely sharp during assembly, so gloves are not optional.
6. Brinly 40 Inch Combination Aerator Spreader – Best for Aerating and Seeding in One Pass
Brinly Tow Behind Combination Aerator Spreader with Weight Tray, 40-Inch, Flat Black
2 in 1 aerator and spreader
100 lb steel hopper
132 tine tips
2 in depth
75 lb tray
Pros
- Drops seed
- fertilizer or lime while aerating
- All steel 100 lb hopper resists twisting
- Calibrated flow control for even spread patterns
- 3-D galvanized tines resist bending
Cons
- 75 lb tray is smaller than dedicated aerator trays
- 2 inch depth versus 3 inch core machines
This is the workflow pick. The steel hopper drops seed, fertilizer or lime while the tine tips perforate the soil, so material lands directly in the open channels instead of on top of the lawn, where it washes away or gets raked up.
It comes together quickly with a universal hitch pin included, and the all-steel 100 lb hopper resists twisting and flexing while the calibrated flow control keeps spread patterns even.
What you give up is depth and ballast. Penetration caps at 2 inches rather than the 3 inches of a dedicated core machine, and the weight tray holds 75 pounds, less than the tray on either Brinly aerator above. The 3-D galvanized tines are the same design used in the heavier spike model, so tine quality is not the issue here.
The average rating is also the lowest here, and the complaints cluster on ballast limits and shallow penetration rather than build quality. For aeration alone, the dedicated plug units do the job better.
Who this aerator suits
It suits owners running a fall overseeding program who want one pass instead of two, and owners who lime on a schedule. It saves real time on that specific job.
Where it falls short
The 75 lb tray and 2 inch depth make it a compromise on hard ground, and the hopper adds bulk and weight for anyone only aerating. On a heavy clay yard, a dedicated core aerator is the better buy.
7. Craftsman 36 Inch Tow Behind Spike Aerator – Best for Small Yards
CRAFTSMAN (CMXGZBF7124336), 36-Inch Tow Spike Tow Behind Spike Aerator for Aerating Lawns; 9 Galvanized Steel Disks, 90lbs Capacity Weight Tray for Better Aeration, Universal Hitch, Red
36 inch working width
9 spike disks
80 lb tray
10-gauge frame
3 year warranty
Pros
- 9 galvanized steel spike disks
- 36 inch width suits quarter-acre lots
- 10-gauge steel frame
- Adjustable hitch fits varied tractor heights
- 3 year limited warranty
Cons
- Assembly instructions omit steps
- Needs the tray fully loaded to penetrate hard soil
- 36 inch width is narrower than 40 inch rivals
For a lot of a quarter acre or slightly more, 40 inches of width is wasted on turning radius. The 36 inch footprint here turns tighter, stores more easily and carries less mass behind the tractor, which makes it the sensible size when you are not covering acres.
Nine galvanized spike disks on a 10-gauge steel frame punch roughly 1.5 to 2 inch slits across the lawn, and the adjustable universal hitch accommodates different tractor heights so it fits a wide range of riding mowers.
One specification deserves a warning. The listing references a 90 lb tray capacity, but the actual enclosed tray is rated at 80 lb, and owners report needing it fully loaded before it will break through tough soil. Check your tractor hitch rating before you fill it.
Owners also mention unclear assembly documentation with some parts unlabelled, so budget an extra hour. Beyond that, feedback centers on a well made alloy steel machine that punches clean slits and can be paired with mowing for single-pass lawn care.
Who this aerator suits
This suits owners of compact riding mowers on smaller lots who want a spike aerator for overseeding and general conditioning without carrying a 40 or 48 inch frame around. Several owners pair it with mowing for single-pass lawn care.
Where it falls short
At 1.5 to 2 inches, the slits are shallow and the 36 inch width means more passes per acre than the larger units. If your soil is compacted clay, the limited tray capacity and depth work against you.
8. Suchtale 40 Inch Tow Behind Spike Aerator – Most Versatile
Suchtale 40-Inch Tow Behind Spike Aerator with Galvanized Steel Tines, Durable Lawn Aerator Soil Penetrator Spikes Tractor with Extra-Wide Tow Bar for Lawn and Farm, Black
10 steel tine stars
2 in penetration
110 lb tray
39.5 lb unit
Powder-coat finish
Pros
- 10 star tines with 10 spike tips each
- Independently rotating tines cut skipped areas in turns
- Steel tray accepts 110 lbs of ballast
- Illustrated manual with parts breakdown
- Powder-coat finish resists rust
Cons
- Tow arms bent on rocky ground
- Spikes bent quickly on stones
- Too short for some golf carts
This is the value play in a 40 inch package. Ten star-shaped steel tines with 8 inch diameters and uneven tips each drive into compacted soil up to 2 inches, and the independently rotating design keeps them turning through tractor turns so you lose fewer areas between passes.
At 39.5 pounds it is easy to lift into place, and the thicker gauge of the adjust handle is a stronger detail than the light parts typically used at this level. The powder-coat finish and nylon spacers between each star support a long service life.
The assembly experience is a genuine strength here. Owners single out the pictorial manual with a full parts breakdown as clearer than the paperwork shipped with several premium competitors, and many report it working as well as a paid lawn service.
Durability is where the reviews split. A smaller set of owners report tow arms twisting, spikes bending within minutes on rocky ground, and both tires coming off the wheels after a single use. It is also reported as too short for some golf carts, so measure your hitch reach.
Who this aerator suits
Good for soft, established turf on a mid-size lot where you want spike aeration and overseeding at a modest outlay. The 110 lb tray is generous for the category and the rotating tines handle turns well.
Where it falls short
If your property has rocks, roots or thin soil, the tines and tow arms are the first things to go. Check the hitch reach for carts and compact tractors before ordering, since length is a common complaint.
9. Craftsman 40 Inch Tow Behind Plug Aerator – Best for Heavy Clay
Craftsman 40 Inch Tow Behind Lawn Plug Aerator with 24 Galvanized Steel Coring Points and 140 lb Weight Tray
24 coring points
3 in plug depth
140 lb tray
78.8 lb unit
Flat-free tires
Pros
- 24 galvanized coring points pull 3 inch plugs
- 140 lb weight tray for tough soil
- Stores vertically against a wall
- Flat-free tires need no maintenance
- 3 year limited warranty
Cons
- Cores must be dried and dispersed
- 78.8 lb build is heavy to move without a tractor
This is the compact tractor answer. Forty inches of width, 24 galvanized steel coring points, and a 140 lb weight tray give it the ballast headroom you want on hard ground without the 48 inch turning radius of the biggest machines.
Owners rate it highly for exactly that combination, with a 4.4 average across its reviews. The 3 inch plug depth is at the top of the range for core machines here, and the alloy steel frame carries a limited warranty from the manufacturer.
Storage is the quiet advantage. The lift handle release system lets the unit tip onto its side and store vertically against a garage wall, which matters more than it sounds when you are trying to fit a mower, a trailer and an aerator into the same bay.
Flat-free tires mean no pressure checks before every session, and they roll reliably across lawn terrain. The same cores caveat applies as with any plug machine: leave them to dry, then break them down with a second mowing pass or a rake.
Who this aerator suits
Owners of mid-size riding mowers on clay or heavily trafficked lawns, especially yards with pet paths and play areas where the ground is pressed down every week. It is a manageable width for most residential lots.
Where it falls short
At 78.8 pounds it is not something you want to reposition by hand, and it performs best on adequately moist lawns. If you need a very wide machine for open acreage, the 48 inch plug aerator covers more per pass.
10. Yard Tuff 36 Inch Drum Spike Aerator – Best for Water Ballast
Yard Tuff Drum 36 Inch Wide Behind Lawn Mower ATV Yard Grass Aerator Roller with 78 Steel Spikes and 24 Gallon Water Holder for Gardening
36 inch drum
78 steel spikes
24 gallon water fill
2 grease points
125 lb empty
Pros
- Water-filled drum adds weight while watering
- 78 steel spikes perforate 2.5 inches deep
- Two grease points keep the drum rolling
- 36 inch drum covers ground quickly
Cons
- 125 lb empty weight needs a tractor or ATV
- Spiked drum is a hazard around children and pets
- One report arrived with missing hardware
Ballast is the whole argument for a drum aerator, and this one takes up to 24 gallons of water in the drum to add weight and water the lawn in the same pass. That solves the number one complaint about tow behind aerators without you buying a stack of pavers.
Seventy-eight steel spikes on a 36 inch drum perforate up to 2.5 inches without uprooting the turf, and two grease points keep the drum spinning freely. Owners like that it attaches to ride-on mowers, zero-turns and ATVs alike.
Rolling the drum lets you aerate while mowing, which saves an entire pass over the lawn. The 44 by 24 by 23 inch footprint is compact, and the wooden crate it arrives in doubles as a storage box, which is a nice touch that shows up in owner reviews.
The weight is real: 125 pounds empty, before you add water. That means a vehicle is required, and the spiked drum profile needs care around children and pets. One owner also reported the crate arriving with no bolts, washers, manual or hitch pin, so inventory the hardware before assembly.
Who this aerator suits
This suits larger properties with a zero-turn or ATV available, and anyone who wants the ballast problem solved neatly. Because the drum waters as it rolls, it works well as a late-season pass on a dry spell.
Where it falls short
It is a bulky option on a residential lot, and it takes time to get rolling. Slow down in tight corners, because the spikes can pull up grass, and expect limited turning performance between beds.
11. BlumeTrec 40 Inch Tow Behind Spike Aerator – Best for ATV and Small Tractor Towing
BlumeTrec 40-Inch Tow Behind Spike Aerator, Pull Behind Lawn Aerator with 10 Galvanized Steel Tines for Aerating Lawns, Soil Penetrator Spikes Tractor with Wheels, Extra-Wide Tow Bar for Garden & Farm
10 galvanized 3D tines
2 in penetration
110 lb tray
Side-control lever
Powder-coated frame
Pros
- 10 galvanized 3-D tines with irregular tips
- 110 lb steel weight tray
- Side-control lever switches transport mode
- Pin-style universal hitch for ATVs and riding mowers
- Assembly tools and gloves included
Cons
- Assembly takes about an hour
- Wheels feel flimsy at full ballast
- Tines bite hard so reversing is difficult
This is a 40 inch spike aerator built for working vehicles rather than tractors. The pin-style universal hitch attaches to ATVs, riding mowers and lawn tractors without tools, and the adjustable hitch covers varied tractor heights.
Ten galvanized 3-D tines with irregular tips on 8 inch stars penetrate up to 2 inches, and they rotate independently to reduce skipped areas during turns. The steel tray holds up to 110 lbs, and an owner reports solid penetration using two car batteries as ballast.
The side-control lever is a genuinely useful design choice. One handle switches between transport mode and working mode, so you are not hunting for a lever behind the drum, and the two rubber tires with bearing-supported wheels keep the unit tracking straight.
Reviewers consistently mention three limits. Assembly takes about an hour even with the supplied tools, the wheels feel under-built once you load cinder blocks, and the tines dig in so tightly that backing up with the aerator attached is awkward. One review reported tines punching only a quarter inch on very hard ground.
Who this aerator suits
ATV and UTV owners, and anyone towing behind a compact riding mower who wants a full 40 inch width without a heavy frame. It is also a sensible overseeding tool for a new lawn where the soil is not yet rock hard.
Where it falls short
The wheels are the weak point at full ballast, and tight tine engagement makes it awkward to reposition. For severely compacted clay you will want more weight capacity and a machine rated for harder ground.
12. Titan 3 FT Tow Behind Drum Spike Aerator – Best for 3 Inch Spike Depth
Titan 3 FT Tow-Behind Drum Spike Aerator Holds up to 25 Gal Water, 3″ Long Welded On Spikes, for ATV UTV and Utility Tractor, Breaks Ground for Better Drainage & Fertilization
36 inch drum
3 in spikes
2.5 in penetration
25 gallon water fill
125 lb empty
Pros
- Longest spikes in the group at 3 inches
- 25 gallon water drum for heavy ballast
- Replaceable bearings keep the drum rolling
- Pin hitch for ATV
- UTV or utility tractor
- Rolling format aerates while mowing
Cons
- 125 lb empty weight makes handling difficult
- Deep spike profile needs care around children and pets
- Bulky footprint including hitch
This drum unit has the longest spikes we found. Three inch spikes that are 0.25 inch thick drive 2.5 inches into the soil, which is a deeper perforating action than any of the star-wheel spike aerators in this roundup, and it does it while you roll.
The drum holds up to 25 gallons of water through a steel side fill cap, so ballast and irrigation happen together. Replaceable bearings on the drum keep it turning smoothly over multiple seasons, which matters for a heavy rotating drum.
Buyers with an ATV, a UTV or a small utility tractor get a pin-style hitch that connects easily, and the rolling drum format lets you aerate while mowing. The wide drum over a 36 inch working width gives it a stable, momentum-driven feel on flat ground.
Trade-offs are predictable. At 125 pounds empty it is one of the heaviest machines here, the footprint is wide and deep once the hitch is included, and the deep spike profile is a hazard around children and pets. It also sits at the heavy end of the drum-style options here.
Who this aerator suits
Utility tractor and UTV owners with acreage who want maximum spike depth and a self-ballasting drum. The replaceable bearings suit someone who will run it every spring and fall.
Where it falls short
This is not a residential machine. Without a vehicle to move it, the empty weight alone is a problem, and the deep footprint needs a straight run to line up with a mower tongue.
Will My Riding Mower Pull an Aerator?
Most riding mowers can, but the aerator width and ballast have to match the machine. A compact 17 to 20 horsepower tractor on a small deck pulls a 36 or 40 inch aerator comfortably, and should run a 48 inch drum only with a light tray load. A mid-size 20 to 25 horsepower tractor handles 40 and 48 inch plug aerators with a full tray. Zero-turn riders with a rear hitch rated for heavier tongue weight handle wide drums and full ballast without complaint.
The number that trips people up is tongue weight. A 94 pound aerator carrying 100 pounds of ballast is close to 200 pounds hanging off the back of the mower, and the hitch rating on a compact tractor may not cover that. Check the hitch class in your mower manual before you load the tray, and never exceed it.
Two more checks matter. The transport lever has to be reachable from the seat, because getting off the mower at every driveway is the complaint that shows up most often in owner feedback, and the hitch height has to match your tractor, which is why several models here use an adjustable hitch. For reference, our guides to riding lawn mowers built for attachments and residential riding mowers cover the hitch classes in more detail.
Plug Aerator vs Spike Aerator: Which One Do You Need?
Choose a plug aerator when the problem is compaction. Hollow coring spoons lift a 2.5 to 3 inch core of soil out of the ground and leave an open hole that roots grow into, and the removed soil is the proof that you reached the root zone. This is the only option that changes a clay yard or a new-build site.
Choose a spike aerator when the problem is surface density and cleanup. Spikes perforate without removing any soil, so the lawn stays clear of debris when you finish, penetration runs about 1.5 to 2 inches, and the punctures close back up. Spike aerators excel for monthly maintenance, overseeding prep and thin lawns that cannot tolerate cores.
On a compacted riding-mower lawn, the practical rule is simple. If water beads on the surface and the grass refuses to grow in traffic lanes, you need plugs. If the lawn is generally healthy and you just want to open the surface before seeding, spikes will do.
How Much Weight Should Go in the Tray?
Keep enough mass in the tray to make the tines bite, and not so much that your tractor hitch complains. A good starting point on a 40 or 48 inch plug aerator with a 140 to 175 lb tray is 60 to 100 pounds of ballast, which is roughly three or four standard cinder blocks.
The most common real-world answer from owners is the same. An r/lawncare user runs three cinder blocks on the tray of a small John Deere E100 and reports it works fine in moist soil. A Brinly spike owner reported driving a full inch into heavy clay with two and a half cinder blocks, and another owner used two car batteries as ballast.
Pavers, sandbags and bagged topsoil all work, but check two things first. Stay inside the tray capacity printed on your machine, and stay inside your tractor hitch rating, because a fully loaded tray is the single largest tongue load most owners ever put on a mower. If the tractor squats on the hitch or the hood rises under load, you have too much weight on board.
How to Aerate with a Riding Mower in Seven Steps
1. Mow first, at a shorter height than usual, so the plugs have somewhere to go and the tines reach the soil rather than the canopy.
2. Water the lawn the day before. Moist soil cores cleanly and dry soil makes the machine skate, and this single step explains most disappointing results.
3. Clear the yard. Pick up branches, remove hoses and toys, and probe for rocks, because a spike hitting a buried stone bends it.
4. Hitch up and check the connection with the aerator resting on the ground, then load the tray with ballast before you lift the tines.
5. Test the transport lever from the driver’s seat on a straight run. If you cannot reach it comfortably, you will be getting off the mower at every crossing.
6. Aerate at a walking-pace speed. Speed is the enemy of a plug aerator, and you should aim to cover roughly three percent of the lawn area on each pass.
7. Let the cores dry, then break them up with a second mowing pass over the tops in a high mow setting or drag them with a yard rake.
What to Look for When Buying a Tow Behind Aerator
Width is the first filter. Anything under a quarter acre is well served by 36 inches, a half acre to an acre suits 40 inches, and open ground or multiple acres justify 48 inches or a wide drum. Going wider than your lawn costs you maneuverability for coverage you cannot use.
Weight tray capacity is the second filter and the one that decides whether the machine works at all. Look at the rated capacity, not the marketing number, and pair it with a tractor hitch rating that supports the loaded weight. A 175 lb tray gives you far more room to work hard soil than a 75 lb tray.
Third, look at the tine and frame specification. Heat-treated or 3-D galvanized spoons and spikes hold an edge longer than plain steel, powder-coated frames resist rust through wet seasons, and a heavy-gauge frame such as the 10-gauge steel on the 36 inch Craftsman resists bending. Three independently rotating tine sections, as on the Brinly plug model, are a real advantage on a yard with tight end turns.
Fourth, tires and transport. Pneumatic tires roll the smoothest on rough ground but need pressure checks, while flat-free and turf-tread wheels never go flat and handle a loaded tray fine. A transport lever that folds down or sits on a side control saves garage space and time. If you plan to cross driveways often, that lever is not optional. On sloped properties the same tractor-selection logic from our riding mowers tested on inclines roundup applies before you buy.
Finally, think about whether you need a spreader too. A combination aerator and spreader cuts your fall overseeding job in half, at the cost of depth and tray capacity, which makes it a strong pairing with a dedicated tow behind spreader only if you already own a plug machine.
When and How Often to Aerate
Core aeration works best when the grass is actively growing and the soil is moist, which in most regions means late spring and early fall. Early fall is the higher-value window because it gives roots the whole cool season to fill the holes you just made, and spring aeration pairs well with a first fertilizer pass.
Aerate annually on lawns with heavy use, heavy clay or a thatch problem. Skip it on newly seeded or sodded lawns in their first weeks, on ground that is bone dry, and on lawns that already drain well. Weed seeds can germinate in the open holes, so if your lawn has a known crabgrass or summer seedbank problem, plan for a follow-up herbicide pass.
Owning an Aerator vs Renting a Walk-Behind
Renting a walk-behind gets you deeper plugs faster on a single visit, which is why commercial users on LawnSite lean that way. Owners on r/lawncare are more pragmatic about it, calling a 40 inch Brinly tow-behind a purchase that was well worth it because the machine is always available when conditions are right.
The tradeoff is time rather than money once you own a unit. A tow behind covers a large lawn slowly and usually needs two passes, so plan your session accordingly. If you only need one deep aeration every few years on a small lawn, renting wins. If you aerate annually, overseed every fall, or have more than an acre, ownership pays back quickly in convenience.
Maintenance and Storage for Tow Behind Aerators
Clean as you go, because owners most often report tines clogging with soil and roots mid-session. Stop every few passes, knock the drum clean and check that spoons are cutting freely rather than dragging a packed core.
Grease the bearings on drum-style units each season, and on star-wheel models check that the nylon or metal spacers between each star are present and seated, since a missing spacer lets tines wobble. Tighten hardware after the first few passes, because the drum loosens under load.
For storage, hose the unit down and dry it before it goes into the shed, and store plug models upright or on their side where airflow is good rather than flat on a damp floor. The models with a folding hitch or a vertical storage design, such as the 40 inch Craftsman plug aerator, make this step much easier.
Frequently Asked Questions
Are tow behind aerators any good?
Yes, provided you load the weight tray. An unballasted tow behind aerator rolls over compacted soil and pulls nothing. Owners on r/lawncare report that a fully weighted unit pulls real plugs and rips turf, but it is slower and shallower than a rented walk-behind machine.
Which pull-behind aerator is the best?
For most riding mower owners we screened, the Agri-Fab 48 inch tow behind plug aerator is the best all-round choice, with 32 galvanized self-sharpening knives, plugs up to 3 inches deep and a 175 lb weight tray. The Brinly 40 inch plug aerator is the pick for build quality and tight end turns.
What is better, a plug or spike aerator?
A plug aerator is better for compaction because hollow coring spoons remove a 2.5 to 3 inch core and leave an open hole roots can grow into. A spike aerator is better for routine maintenance and overseeding because it perforates up to about 2 inches, leaves no cores to clean up, and its punctures close back up.
How much weight do you need on a pull behind aerator?
Start with 60 to 100 pounds of ballast, roughly three or four cinder blocks, and add more if the drum skates over hard soil. Owners commonly use cinder blocks, pavers, sandbags or even car batteries. Stay inside the tray capacity printed on the machine and inside your tractor hitch rating.
Can I use a riding mower to pull a plug aerator?
Yes, most riding mowers with a rear hitch can pull a tow behind aerator. Match width to power: a compact 17 to 20 hp tractor suits a 36 or 40 inch aerator, while a mid-size tractor or zero-turn handles 48 inch drums and full ballast. Check the hitch class and tongue weight rating before loading the tray.
What are the disadvantages of aerating?
The main drawbacks are time, mess and short-term appearance. Cores sit on the lawn until they dry and are broken up. An unballasted aerator wastes the trip. Aeration can also bring up weed seeds, and a spike aerator that strikes rocks can bend its tines.
The Best Tow Behind Aerator for Your Riding Mower
After screening twelve units against tractor power, hitch fit, ballast capacity and real plug depth, the Agri-Fab 48 inch tow behind plug aerator is our pick for the best tow behind aerators for riding mowers. It ties for the deepest plug depth in the group, has the largest tray capacity of any machine here, adds a transport handle that works from the seat, and has the longest review history among these picks.
If a 48 inch frame is too much for your yard, the Brinly 40 inch plug aerator is the stronger-built machine, the Agri-Fab 40 inch plug aerator is the balanced value choice, and the 36 inch Craftsman spike aerator fits a quarter-acre lot without wasted width. Load the tray, water the lawn first, and go slowly. That is the whole difference between a disappointing afternoon and a lawn that thickens up by midsummer.
