If you own a riding mower and want to punch holes in your lawn for seed, water or topdressing, the best spike aerators for riding mowers do that job faster than any walk-behind tool. They hitch to the rear of a lawn tractor and put rows of solid steel spikes into the ground as you drive.
Before the list, one honest note. A spike aerator does not remove soil, so it is not the answer to heavy compaction in clay. What it does well is press seed into the surface, prep for topdressing, puncture a shallow thatch layer and open up loose soil that has packed at the top. If your lawn is genuinely compacted, you want a hollow-tine core aerator or a rental instead. We cover the reasoning in detail further down.
We compared ten tow-behind spike aerators across the specs that actually matter: working width, spike count, spike material, weight tray capacity, hitch type and tow bar construction. Nine of these ten also appear in our broader lawn aerator guide, where we set them against plug and core machines.

Core vs Spike Aerator: What Each One Actually Does
This is the distinction that decides your purchase, so it is worth being precise about the mechanism.
Tine type. A spike aerator uses solid steel spikes on star wheels or a spiked drum. A core or plug aerator uses hollow tines that cut a plug of turf and soil and push it to the surface.
What happens to the soil. Solid spikes compress soil sideways and open the surface. Hollow tines physically remove a core and leave a hole behind.
Compaction relief. Minimal for spikes. This is the job hollow tines were built for, and it is why extension guidance points clay and heavily trafficked lawns toward coring.
Best soil fit. Spikes suit loam and sandy soils with light surface compaction. Cores suit clay, builder fill and high-traffic zones.
Debris. A spike aerator leaves nothing to rake. A core aerator leaves plugs you must collect, break up or leave to dry.
Typical cost tier. Spike aerators sit at the budget end of the implement market. Core aerators cost several times more and heavier to tow.
Bottom line: buy a spike aerator for seed work, topdress prep and thatch puncture. Buy or rent a core aerator when your lawn is hard-packed and you need soil removed.
1. Agri-Fab 45-0544 40 in. Tow Behind Spike Aerator – Best Overall
Agri-Fab 45-0544 40 inch Tow Behind Spike Aerator for Aerating Lawns; 10 Galvanized Steel Spike Disks, Universal Hitch, Black
40 in working width
100 lb weight tray
10 galvanized steel spike disks
37.3 lb item weight
Pros
- Made in USA steel construction
- Ten galvanized spike disks spread across a 40 inch swath
- Folding hitch for tighter storage
- Best documented unit with 1054 owner ratings
Cons
- Spikes punch holes rather than removing soil cores
- Tray must be loaded before it will penetrate
- Sharp tines need care during assembly
This is the unit I recommend to most people who ask me which spike aerator to buy. It has the largest review base of anything we tested at 1054 ratings, a 40 inch working width and a 100 pound weight tray. Made in the USA, it is also the unit with the deepest documented owner history in the group, so the first-hand reports below are unusually well evidenced.
Owners consistently single out the folding hitch, which folds the tow bar out of the way and lets the unit sit against a wall in a garage. At 37.3 pounds it is also one of the heavier steel-framed options here, which is a fair trade for not flexing in compacted ground.
What 100 pounds of ballast actually buys you
Unballasted, the spikes mostly scratch the surface. Add the full 100 pounds and the spikes open slits roughly 2 inches deep on loam. On clay you will feel the mower bog down, and that resistance means the tines are going in rather than bouncing off.
Where this one falls short
The 100 pound tray is smaller than the Brinly SAT2-40BH-P’s 150 pound tray, so on hard ground you may want two passes instead of one. It also makes no attempt to remove cores, so if compaction is your real problem this is the wrong purchase.
2. Brinly SAT2-40BH-P 40 in. Tow Behind Spike Aerator – Best Built
Brinly SAT2-40BH-P Tow Behind Spike Aerator with Transport Wheels, 40″ – Hammered Black
11 tine stars with 12 tips each
Up to 2 in penetration
150 lb weight tray
5/8 in solid steel axle
Pros
- Largest weight tray capacity we found at 150 lbs
- 11 rotating 8 inch stars give wide tine coverage
- 3-D galvanized tines resist rust and bending
- Single lever transport wheels for crossing driveways
Cons
- Axle spacers are easy to miscount
- Assembly illustrations are conflicting
- Mislabeled hardware in the parts bag
The Brinly SAT2-40BH-P is the most mechanically substantial spike aerator of the ten. Eleven tine stars, each 8 inches across with 12 spike tips, ride on a 5/8 inch solid steel axle with nylon spacers between each star. The weight tray is rated for 150 pounds, the highest capacity in this roundup.
Owners report that two cinder blocks push the tines about an inch into clay, and several run this unit monthly rather than twice a year. The patent-pending 3-D galvanized tines are the reason: they are shaped to resist bending when they meet a buried root.
Watch the spacer count during assembly
The single most repeated complaint is assembly. Count the nylon spacers as you go, because too few let the star wheels develop wobble and eventually come apart under load. The illustrated instructions also contain conflicting diagrams, so budget an extra hour.
Why it is not our first pick
It scores higher than our top pick at 4.3 across 739 ratings, but its build takes longer to put together and its stars concentrate more spike tips on the same axle. For most lawns the Agri-Fab is the easier ownership experience.
3. CRAFTSMAN 36 in. Tow Behind Spike Aerator – Best Value
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 in working width
80 lb enclosed tray
10-gauge steel frame
Adjustable universal hitch
Pros
- Adjustable hitch fits a wide range of riding mowers
- 10-gauge steel frame holds up to repeated seasons
- Includes a hitch pin
Cons
- Assembly instructions are unclear and incomplete
- Narrower than 40 inch units so more passes
- Bounces along the surface unless weighted
This CRAFTSMAN-branded tow-behind, built by Agri-Fab, sits at the value end of the mid tier. The 10-gauge steel frame is heavier gauge than most competitors in this price band, and the adjustable hitch is what lets it fit tractors of different hitch heights.
Reviews are nearly unanimous on one point: almost everyone loads cinder blocks or sand bags onto the tray. Once weighted, owners report slits of 1.5 to 2 inches, and several compare it favorably against the cost of renting a core aerator.
Capacity discrepancy worth knowing
The listing title states a 90 pound tray capacity while the technical details list 80 pounds. Plan on the lower figure. If you want more ballast headroom for clay, the Brinly SAT2-40BH-P carries 150 pounds.
The paperwork is the weak point
Multiple reviews describe instructions that skip steps and mislabel hardware. Set aside time to sort the parts before you head to the lawn, and check the hitch pin is included.
4. Suchtale 40 in. Tow Behind Spike Aerator – Best When You Turn a Lot
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
40 in working width
10 star wheels, 110 lb tray
Pin style quick hitch
39.5 lb item weight
Pros
- Star wheels rotate independently through turns
- Thick channel tow bar resists flexing
- Illustrated manual with parts breakdown
- Works well on moist soil after rain
Cons
- Hitch arms and tines bend if you hit rocks
- Tow bar can be short for some club carts
- Included wrenches are low quality
If your lawn is broken up by trees, beds and corners, the Suchtale is the one I would pick. Its 10 star wheels each have 10 uneven tips and rotate independently, so they keep revolving when you turn rather than skidding and leaving bare patches.
The powder-coated all-steel frame, reinforced side plates and a 6 mm adjustment handle make this one of the better-built units at this level. Owners like the pictorial manual, and several report visible improvement after replacing a paid aeration visit.
Ballast and soil moisture matter more than anything
Reviewers confirm that an 80 pound tray load plus moist soil produces good penetration. On bone-dry ground this unit tends to skim. Water the lawn the day before you run it.
Do not back into the spikes
The most common hardware failure reported is bending hitch arms and tines after reversing into the unit or clipping rocks. Raise the unit on its transport setting before you back up.
5. Brinly SA2-40BH-P 40 in. Tow Behind Spike Aerator – Best for Frequent Runs
Brinly SA2-40BH-P Tow Behind Spike Aerator with Double Tow Bar, 40″ – Hammered Black
40 in working width
110 lb weight tray
28.9 lb bare weight
10 star wheels with 12 tips
Pros
- Runs monthly on clay without complaint
- Simple to hitch and unhitch
- Handles quickly between passes
- Plastic axle will not freeze in cold weather
Cons
- Bare weight is light so ballast is essential
- Reports of a bent spindle below the tray limit
- No spare hardware included
This second Brinly is lighter at 28.9 pounds, which is exactly why owners with clay soil like it. Light enough to move around on its own, small enough to store against a fence, and it handles quickly once you are working in passes.
It carries the same 3-D galvanized tines as the SAT2 model, with 10 star wheels of 12 tips each penetrating up to 2 inches. The double tow bar and reinforced side plates are appropriate for a unit you might run monthly rather than twice a year.
Load the tray or it will not work
Several reviews call it underbuilt in hard-packed soil, and a few owners report a bent metal spindle after light use despite staying well under the 110 pound tray rating. Check the spindle for straightness each season before loading it.
The lowest rating in our group
At 4.1 across 216 ratings, this is the weakest score we recorded. That tracks with its low bare weight, which is a design choice for portability rather than a flaw.
6. BlumeTrec 40 in. Tow Behind Spike Aerator – Best for Small Lawns and New Seed
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
40 in working width
110 lb weight tray
10 star tines, 11 tips each
Two 8 inch rubber tires
Pros
- Side lever switches transport and working modes
- Two 8 inch rubber tires roll over driveways
- Works well for overseeding a new lawn
- Includes a pin style hitch and illustrated manual
Cons
- Wheels flex under a loaded tray
- Shallow penetration in hard soil
- Assembly takes longer than expected
Owners use this BlumeTrec unit mostly for overseeding work, pressing seed into a thin topsoil before it dries out. One reviewer reported that two old car batteries on the tray gave solid digging-in on a small yard, which tells you how light the frame feels empty.
The 10 galvanized 3-D star tines carry 11 irregular tips each for up to 2 inches of penetration, and the side-control lever makes switching between transport and working mode a one-handed job.
Good for soft ground, weak on hard ground
The recurring complaints are wheels that flex noticeably once the tray is loaded and shallow tine penetration in compacted soil. If you have a small lawn with loose soil, that is an acceptable trade. On hard ground, look at a heavier frame.
Be careful reversing
This unit is unforgiving if you back into the spikes once they are buried. The tow bar is short enough that backing up feels natural, which is exactly the problem.
7. Seeutek 40 in. Heavy Duty Tow Behind Spike Aerator – Easiest to Assemble
Seeutek 40Inch Tow Behind Spike Aerator – Heavy Duty Rolling Lawn Aerators
Ten 8 inch 3-D star tines
330 lb tray capacity
42 lb item weight
Partial assembly only
Pros
- Minimal assembly
- just a handle and two wheels
- Cement brick straps and gloves included
- Reinforced square tube rear bracket
- Oversized rubber wheels aid leverage
Cons
- Small review base so durability is unproven
- Claimed 330 lb tray capacity unverified by owners
Assembly is where most spike aerators lose their owners, and the Seeutek largely sidesteps it. You put on a handle and two wheels. Brick straps and a pair of gloves come in the box, which saves a trip for the loading supplies you would have to buy anyway.
The frame is all steel with reinforced side panels and a solid steel axle, and the rear bracket is a reinforced square tube rather than the flat plate used on cheaper units. Ten 8-inch 3-D star tines with 10 sharp irregular tips each penetrate up to 2 inches.
Treat the tray rating as unproven
The listing states a tray capacity up to 330 pounds. Owners have not tested that figure, and it is far beyond what most riding mowers should be towing. Load to what your mower’s towing capacity allows, not to the number on the page.
Judge it on a longer track record
With 42 ratings, there is not yet enough owner history to say how it holds up over several seasons. That is the main reason it sits below the higher-reviewed units here.
8. Yard Tuff 36 in. Drum Spike Aerator – Best Drum Format
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 in drum with 78 steel spikes
Up to 2.5 in penetration
24 gallon water fill
125 lb item weight
Pros
- Water fill gives the deepest puncture in this roundup
- 78 steel spikes cover a 36 inch drum
- Aerates and waters in the same pass
- Grease points keep the drum rolling freely
Cons
- 125 lb dry weight is heavy to move by hand
- Bulky to turn between passes
- One buyer received missing hardware
A drum aerator works differently from the star-wheel designs above. Instead of separate wheels on an axle, the Yard Tuff carries 78 steel spikes on a single 36-inch drum that you fill with water. Adding up to 24 gallons is what drives the spikes to a stated 2.5 inches of penetration, the deepest we saw.
Owners with half-acre-plus lawns report the biggest visible change of any unit here, and several frame it as paying for itself against repeated rentals. Because it waters as it aerates, you can do two jobs in one pass.
Weight is the trade-off
At 125 pounds dry and 44 by 24 by 23 inches, this is a two-person job to reposition and a wide machine to maneuver. Steer in arcs rather than straight lines for more even coverage, as several owners recommend.
Mark your sprinkler heads first
Deep spikes can pull up turf around irrigation heads. Flag them before you start and slow down in tight corners. One buyer also reported arriving without bolts, washers or the hitch pin.
9. Titan 3 FT Tow-Behind Drum Spike Aerator – Best for Utility Tractor Work
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
3 in welded spikes to 2.5 in deep
25 gallon water fill
36 in drum, 14 in diameter
125 lb item weight
Pros
- 3 inch welded on spikes give the deepest puncture here
- Replaceable bearings keep the drum rolling
- Pin style hitch fits ATVs
- UTVs and small utility tractors
- Heavy steel build for repeated seasonal use
Cons
- Highest cost in the group and a 4.1 rating
- 125 lb dry weight is awkward without a vehicle
- 63 inch footprint including hitch needs turning room
The Titan uses a different spike geometry from the Yard Tuff. Its spikes are 3 inches long and 0.25 inch thick, welded on rather than mounted in a star, driven to a stated 2.5 inches deep by up to 25 gallons of water in the fill drum. The thick spikes roll over the lawn rather than snagging on it.
It is aimed at drainage and fertilizer uptake work behind ATVs, UTVs and small utility tractors rather than at lawn tractors specifically. If your property is acreage-scale, that framing makes sense. If you have a riding mower and a half acre, the turning radius is the problem.
Bearings are a genuine advantage
The drum runs on replaceable bearings, so a worn bearing is a serviceable part rather than the end of the unit. That matters for a machine expected to survive repeated seasonal work.
Where the value is hard to justify
It carries the lowest rating of the drum units at 4.1 across 43 ratings, and its 63-inch depth including the hitch needs real turning room. For most homeowners the other drum covers the same depth.
10. VEVOR 32 in. Tow Behind Aerator – Budget Pick for Small Lawns
VEVOR Tow Behind Plug Aerator, 32 in Lawn Spike Aerator with Universal Hitch, Heavy Duty & Rust-Resistant, Pull Behind Spike Aerator Tool with Folded Edge Tray, for Farmland & Garden Tractors
32 in working width
100 lb weight tray with strap slots
Up to 2 in penetration
27.6 lb item weight
Pros
- Lowest cost in this roundup
- Highest average rating at 4.4 with no 1 or 2 star reviews
- Fully welded steel frame with reinforced hardware
- Tray strap slots keep sandbags from shifting
Cons
- Narrowest working width means more passes
- Only 16 ratings so little long term feedback
- Fewer tines than the 40 inch units
The VEVOR LASS002 is the one to buy if your lawn is small, your gate is narrow and your budget is the deciding factor. At 32 inches it is the narrowest unit here, which means more passes, but on a lawn under a quarter acre that trade rarely matters.
The frame is fully welded high-strength steel with reinforced hardware, the tray has reinforced folded edges front and back, and the strap slots stop sand bags from shifting on a slope. Socket tool and wrench are included, so assembly needs no extra purchases.
Clean rating history, thin history overall
At 4.4 with no 1 or 2 star reviews, the distribution is the cleanest in the group. Sixteen ratings is not much of a sample though, so treat the rating as encouraging rather than proven over seasons.
Width is the compromise
Fewer tines over a narrower swath means you will make more passes to cover the same lawn. On a small property that is fine. On anything over a half acre, a 40 inch unit will save you time on every run.
How to Choose a Tow Behind Spike Aerator
Match the hitch before anything else
A tow-behind aerator is useless if it will not connect. Most units in this group use a pin-style quick hitch or a universal hitch with an adjustable drop arm, which is the most forgiving option across different tractor heights. Check that your riding mower has a rear hitch at all, because many zero-turn mowers do not come with one and need a hitch kit installed.
Do not load more than your mower’s rated towing capacity. The heavier drum units here, at 125 pounds dry before water, are generally tractor jobs rather than riding mower jobs.
Size the width to the lawn and the gate
A 32 inch swath suits lawns under a quarter acre and narrow gates. A 36 to 40 inch unit covers a quarter acre to half acre in fewer passes. A 48 inch width is only worth it above half an acre, and few riding-mower owners see the time saved. Measure your narrowest gate and any path before you commit to a width.
Do the ballast math
Empty, most of these units skim the surface. Add 100 to 150 pounds of ballast depending on tray rating, using concrete blocks, pavers or sand bags, and the spikes will cut roughly 2 inches. On clay soil expect the mower to slow noticeably when the spikes are working, because that drag is the penetration.
Look at the tow bar and axle, not just the tines
An extra-strength double tow bar and a 5/8 inch solid steel axle resist the twisting force that comes with a loaded tray. Cheaper units use a channel-section bar and a smaller spindle, and that is where bending reports come from.
Check the wheel and lever arrangement
A single-lever transport wheel system lets you roll the unit across driveways and sidewalks without lifting it. Four-wheel designs with larger rubber tires give more leverage over uneven ground but cost more and take more space to turn.
How to Aerate With a Spike Aerator Step by Step
Mow and clear first. Short grass and a clean surface let the spikes reach the soil instead of shredding debris.
Water the lawn the day before. Moist soil is essential. On bone-dry ground the spikes skim and on saturated ground the turf tears.
Flag sprinkler heads and shallow lines. Mark heads and know where irrigation runs sit before you start.
Load the weight tray. Add 100 to 150 pounds within the tray rating and your mower’s towing limit.
Make slow overlapping passes. Walk the passes so each one overlaps the last slightly.
Cross pass at 90 degrees on areas that are still compacted.
Overseed promptly if that was the goal, then water the lawn to move seed into the holes you just made.
Timing depends on your grass. Cool-season lawns such as fescue, ryegrass and Kentucky bluegrass are best aerated in early fall or spring. Warm-season lawns such as bermuda and zoysia are better served in late spring as they come out of dormancy. Never aerate heat-stressed or dormant turf.
One expectation worth setting: experienced owners repeatedly note that a properly working aerator is hard to pull, because working means the spikes are penetrating. If the unit feels light, add ballast before you decide it is ineffective.
Frequently Asked Questions
Is a spike aerator worth it?
Yes, for seed-to-soil contact, topdress prep, shallow thatch puncture and light compaction on loose soil. No, for genuine compaction relief on clay, because solid tines push soil sideways rather than removing it. If you already own a riding mower with a rear hitch, the purchase makes sense for surface-level work.
What is better, a spike or plug aerator?
A plug or core aerator is better for relieving compaction because its hollow tines remove a core of soil. A spike aerator is better for cheap, fast surface work such as pressing seed, prepping for topdressing and puncturing a shallow thatch layer, and it leaves no plugs to clean up.
What size spike aerator do I need for my lawn?
A 32 inch swath suits lawns under a quarter acre and narrow gates. A 36 to 40 inch width covers a quarter acre to half acre in fewer passes. Wider is only worth it above half an acre, and you should measure your narrowest gate before buying.
Can you tow a spike aerator behind a zero-turn riding mower?
Only if your mower has a rear hitch and enough towing capacity for the loaded unit. Many zero-turn mowers ship without a rear hitch and need a hitch kit installed. Heavy drum aerators weighing 125 pounds dry plus water are generally tractor jobs rather than zero-turn jobs.
How much weight does a spike aerator tray hold?
Most trays in this category are rated between 80 and 150 pounds, and the Seeutek unit claims 330 pounds. In practice you want 100 to 150 pounds of ballast on ordinary soil, and never more than your riding mower’s rated towing capacity.
Do lawn aeration spike shoes work?
Spike shoes work by concentrating your body weight on solid spikes, which is the same mechanism as a tow-behind spike aerator but with far less force and an arbitrary pattern. For a riding mower owner, a tow-behind covers the same ground with the same tines in a fraction of the time.
When should I aerate my lawn?
Aerate cool-season lawns such as fescue and Kentucky bluegrass in early fall or spring. Aerate warm-season lawns such as bermuda and zoysia in late spring as they leave dormancy. Do not aerate heat-stressed or dormant turf, and water the lawn the day before so the spikes penetrate instead of skimming.
Before you settle on a machine, it helps to know what the alternatives cost you in time and storage space. We walk through those trade-offs in our riding mower guide, including which platforms actually have a usable rear hitch.
The Bottom Line
For most riding mower owners, the Agri-Fab 45-0544 is the spike aerator to buy: a 40 inch swath, a 100 pound tray, and more owner feedback than anything else we compared. If you want the most ballast capacity and the heaviest steel, the Brinly SAT2-40BH-P takes 150 pounds and holds 11 star wheels. If cost is the deciding factor on a lawn under a quarter acre, the VEVOR 32 inch unit is the one.
Use a spike aerator for seed-to-soil contact, topdress prep, thatch puncture and light surface compaction. For anything deeper, rent a hollow-tine core aerator. You can also see how these tools compare in our full lawn aerator review.
