10 Best Tow Behind Lawn Aerators for Riding Mowers (October 2026)

Yes, tow-behind aerators work, and for anyone who already owns a riding mower they are the cheapest way to relieve compaction across a quarter acre or more. The catch is honest and worth repeating: they pull far less soil per pass than a powered core aerator, they need a fully loaded weight tray to bite past about an inch, and most owners make two to three passes before they see a real result. That is exactly what the top-voted answer on r/lawncare says about the category, and it is why we rated these machines on ballast capacity and core quality rather than on width alone.

Below is our ranking of the best tow behind lawn aerators for riding mowers, chosen from ten tow-behind models we compared spec by spec and owner review by owner review. We weighted four things: whether the tines genuinely pull cores, how many pounds the weight tray accepts, whether the hitch actually fits a riding mower or zero-turn, and how long owners report the frame and tines lasting.

Two things this list does not do. It does not rank by price, and it does not pretend a spike aerator does the same job as a plug aerator. We use r/lawncare, thelawnforum.com, greentractortalk.com and tractorbynet.com owner reports to fill in the durability picture that spec sheets leave out, and we flag the hitch and tow-capacity questions that riders ask most often.

Top 3 Tow Behind Aerator Picks for 2026

All 10 Aerators Side by Side in 2026

1. Agri-Fab 48 Inch Tow Behind Plug Aerator – The One With the Deepest Tray in the Mainstream Tier

This is the machine we would put behind most riding mowers. Agri-Fab has been building this 48 inch platform for years and the owner record reflects it, with 2471 reviews averaging 4.2 stars. The 32 galvanized self-sharpening knives are the reason: a blunt tine is a tine that skips, and self-sharpening edges keep pulling plugs at the same depth in October as they did in April.

The weight tray is the story here. It accepts up to 175 pounds, which is more than any other mainstream plug aerator in this group and only beaten by the 48 inch Brinly further down. Owners on r/lawncare who load that tray with concrete blocks and run a slow second pass are the ones who report the classic core-aerator result: a lawn that drinks water instead of shedding it.

Depth is the honest weakness of the whole category, and this model does not escape it. The listed depth is up to 3 inches, and you only see anything close to that in soil that has been watered the day before. Dry ground will bounce the spoons off the surface no matter what you load the tray with, so irrigate first and aerate second.

Flat-free tires mean no flats on a property with gravel driveways and coral rock, and the cantilever transport handle lifts the reel from the seat, which saves dragging spikes across a driveway every time you cross it. Owners who tow with a modest engine have no trouble with the pull, and one r/lawncare user reports pulling a 48 inch core aerator behind a 15hp Husqvarna lawn tractor with no complaint beyond speed.

How It Fits a Riding Mower or Zero-Turn

The universal hitch is a drop-pin style clevis that most lawn tractors accept with no adapter, and the 175 pound tray is the highest capacity you can hang behind a mid-size tractor without worrying about the load. Check your mower’s tow rating before you fill it, though. A rider rated for 400 pounds total leaves you 300 pounds of headroom after the 94 pound frame, which is comfortable.

Where This One Falls Short

A 48 inch swath is the widest in this roundup, and that width is a benefit on open ground and a nuisance anywhere with beds, trees or tight turns. Turning at the end of a pass is also where turf damage shows up most, and owners who do it abruptly will tear more grass than they need to. Budget an hour or two of assembly before the first pass, and expect the frame to be a two-person lift off the hitch.

2. Brinly 40 Inch Tow Behind Plug Aerator – The Highest Rated Corer in the Set

At 4.4 stars across 977 reviews, this is the best-rated aerator we evaluated, and the reason shows up in the soil. The 24 heat-treated 16-gauge spoons are narrower than the competition, which means they push into compacted ground with less ballast than a wider spoon demands. Owners report pulling clean 3 inch cores with a moderate load in the tray rather than a fully loaded one.

The three independently rotating welded tine sections are the detail most people miss until they have used one. On a standard reel, every spoon hits the ground at once and the frame bucks on a turn. Splitting the tine field into three separately rotating sections lets the machine track through a curve without gouging turf, and that is why this model shows so few complaints about damaged grass at the end of a pass.

Construction is all steel throughout, with a fully enclosed 150 pound weight tray that will not let a concrete block slide out over your driveway, and 10 inch semi-pneumatic rubber tread tires that roll over uneven ground without the harsh bounce of a solid wheel. The single transport lever engages transport mode from the seat, which matters more than it sounds when you are crossing a driveway four times in an afternoon.

Buyers consistently describe this one as paying for itself quickly against a rental. A member on greentractortalk.com put it plainly in the durability thread: a low-cost spike aerator they owned fell apart after a couple of seasons, while a heavier build kept performing year after year. That is the whole argument for spending more on steel up front.

Why Owners Rate It Highest

Two things earn the rating. First, penetration that does not punish you for a modest ballast load. Second, a hitch that owners confirm fits lawn tractors, most zero-turn mowers and ATVs with a single pin, which removes the guesswork that slows down a first purchase. The 63.9 pound weight is also the lowest of the large plug aerators here, so loading the tray is not a two-person job.

Where It Costs You

It is the most expensive 40 inch plug aerator in this roundup, and the all-steel frame means it is a stubborn lift into a shed for one person. The 150 pound tray is also 25 pounds short of what the 48 inch Brinly accepts, so if your soil is genuinely heavy clay and you plan to run 180 pounds of ballast, the wider model below is the better machine.

3. Agri-Fab 40 Inch Tow Behind Plug Aerator – Best Balance of Width, Tires and Storage

If your lawn is close to half an acre rather than a full acre or more, this 40 inch model is the efficient middle ground. Forty inches means you finish a typical residential lawn in fewer passes than a 36 inch spike unit, and you are not fighting a 48 inch machine for clearance every time you turn.

The pneumatic tires are the quiet advantage. Ten inch by 3 inch pneumatics absorb bumps and roots that would make a solid wheel bounce the frame and skip spoons out of the ground, so the aerator stays engaged on uneven lots. The 73.8 pound frame is light enough to reposition by yourself, which you will appreciate after the first long afternoon.

Twenty-four galvanized sharpened coring knives pull real plugs, and owners credit the machine with consistent results when the tray is loaded and the lawn is damp. The single lever transport handle folds flat for off-season storage, which is the feature that decides the purchase for anyone with a single-car garage and no room to leave a 40 inch implement unfolded across the floor.

The tradeoff against the 48 inch Agri-Fab is straightforward: fewer passes to finish and eight inches less width to maneuver. Against the Brinly above, you give up some ballasting tolerance and the rotating tine sections. In exchange you get pneumatic tires and a folding handle, and for most suburban lots that is the better trade.

What to Check Before You Buy

Measure the tightest turn on your property and the width of your gate or shed door with the handle folded. Confirm your tractor’s hitch height clears the pin, and check the tow rating against the frame plus whatever you plan to load in the tray. Owners who set up the hitch on a level driveway with the tractor attached report a far smoother first assembly.

Where It Falls Short

Forty inches is narrow by today’s standards, so a full acre will take noticeably longer than with a 48 inch model, and the assembly is not a one-box-no-tools job. The coring knives also need the same ballast discipline as every plug aerator here: an empty tray on compacted soil will skim rather than core, and that is where disappointed buyers end up.

4. Brinly 48 Inch Tow Behind Plug Aerator – The Heaviest Ballast Capacity You Can Hang Behind a Tractor

This is the machine to buy if you have heavy clay and the towing capacity to use it. The fully enclosed weight tray accepts up to 200 pounds, the highest figure in the whole roundup, and the 32 heat-treated 16-gauge spoons across four independently rotating tine sections can put that mass to work across a 48 inch swath. Owners running 140 to 200 pounds of ballast report full-depth plugs in soil that refuses to give for anything smaller.

That capacity is also the reason this one has a shorter review history than its 40 inch sibling. It is a large machine for a large property, and buyers tend to arrive at it after a couple of seasons of renting. Several note that it paid for itself within one or two uses compared with rental rates for a walk-behind core aerator.

Mechanically it is the more sophisticated of the two Brinly plug models. Four rotating sections track through turns more smoothly than three, spoon timing is set to pull evenly, and the 10 inch semi-pneumatic rubber tread tires keep the reel in contact with rolling ground. The universal single pin hitch is confirmed by owners to reach lawn tractors, most zero-turn mowers and ATVs.

Be realistic about the weight. At 82.8 pounds empty before a single block goes on the tray, this is not a machine you lift casually, and owners report it becomes sway prone when fully weighted. Check your tractor’s rated tow capacity first, and remember that the rated figure covers the implement plus all ballast plus anything in the trailer.

Who This Machine Is For

Anyone aerating a full acre or more of compacted clay on a tractor rated for a serious trailer load. If your property is mostly open and the soil fights back, the difference between a 150 pound tray and a 200 pound tray is the difference between punching holes and pulling cores. The four rotating sections also make it the more forgiving option on a property with curves.

Where the Complaints Sit

Assembly is the recurring theme. Fasteners are not sorted into separate bags, the unit is heavy to hold while bolting, and one owner reports the wheel lever plate bending under full ballast. That last item is the part to inspect after your first heavy session, because a bent lever plate turns an easy transport into a two-person job mid-afternoon.

5. Brinly 40 Inch Tow Behind Spike Aerator – Built Like a Tractor Implement, Not a Garden Tool

This spike aerator is built with the same seriousness as the plug models, and that is the reason it earns a spot on a list otherwise full of lighter spike units. The double tow bar and 5/8 inch solid steel axle carry a loaded tray without the flex you feel in a channel-frame import, and the patent-pending 3-D galvanized tines are the thickest steel in the spike category.

Those tines are 8 inch stars with 12 tips each, 11 stars across a 40 inch width, rated to 2 inches of penetration. Owners running two cinder blocks in the tray on heavy clay report roughly 1 inch of actual bite and visible improvement in about four weeks, which is honest spike performance rather than a coring result.

What makes it stand out is the transport system. A single lever engages turf-tread transport wheels, so you can cross a driveway without dragging spikes through it, and it folds down to a footprint that fits most sheds. Spiking also means there are no plugs to rake, no cores to break down, and nothing to collect, which is the quiet reason many owners keep one alongside a plug machine for quick touch-ups.

One r/lawncare user framed the spike-versus-plug tradeoff in a way we agree with: spike aeration opens channels and relieves surface compaction, and a spike tool used consistently is a legitimate maintenance habit. It is just not coring, and anyone expecting pulled soil plugs from this machine will be disappointed.

How to Get the Most From It

Water the lawn the day before. A damp lawn lets the stars bite to their full 2 inch rating, while the same stars on dry soil skip across the surface. Load the tray with concrete blocks evenly distributed so the frame does not lean, and make two passes at a right angle to each other so the channels cross.

Where Ownership Gets Annoying

Assembly is the top complaint, and it is a real cost of ownership. Diagrams in the manual are reported to conflict with each other, the included axle spacers can run thin enough to let tine stars wobble under load, and the spike tips are sharp enough to require gloves during setup. Budget a full afternoon for the first assembly and check the spacers before the first pass.

6. Agri-Fab 40 Inch Tow Behind Spike Aerator – Lightest Frame With a 3 Year Warranty

Sandy and loamy soil does not need coring as much as it needs channeling, and that is where a spike unit makes sense. This Agri-Fab weighs 37.3 pounds, so it is easy to lift onto the hitch, easy to move around a garage corner, and easy to pull up to a shaded part of the lawn without dragging it. On a lighter soil, ten galvanized steel spike disks across a 40 inch width do the job without a heavy machine.

It is also the one budget spike unit here built in the USA, which matters when you are buying something that spends its life outdoors dragging through gravel. The folding hitch collapses for storage, and the whole assembly is straightforward enough that most owners have it running the same afternoon it arrives.

The 100 pound weight tray is the limitation. That is the smallest capacity in this roundup, and it is the difference between punching slits and opening channels in a hard-packed driveway path. Water first, load the tray close to full, and expect slits rather than cores.

For a lawn that is firm but not severe, or for a new yard you are preparing for seed, this is a sensible first machine. For clay that has not been amended in years, a plug aerator with a 150 pound or larger tray will do noticeably more in the same afternoon.

Who Should Buy This One

Owners of lighter soil who want a low-effort annual spike pass with nothing to clean up afterward, and anyone who struggles to lift a 60 to 90 pound implement onto a hitch. It is also a sensible companion to a plug aerator, since spike passes in early spring and coring in fall is a reasonable split for a busy lawn.

Where It Falls Short

On hard or rocky ground the 100 pound tray runs out of authority, and the spikes will not approach the 3 inch depth a plug aerator can reach. A greentractortalk.com owner described the durability contrast that buyers learn the slow way: a low-cost spike unit that fell apart after a couple of years, next to a heavier build still going. This model is sturdier than most of its tier, but it is still the lightest frame we tested.

7. Suchtale 40 Inch Tow Behind Spike Aerator – Best Small-Farm and Field Machine

This 40 inch spike aerator earns its place through its tow bar. The thick channel-shape tow bar and 6 mm adjust handle are visibly heavier than the tubing on typical home-garden spike units, and that is the part that fails when you are pulling across a rough field instead of a manicured lawn. Owners working larger ground report comparable results to a paid aeration service at a fraction of the cost.

The tine layout is the other differentiator. Ten star-shaped tines, 8 inches in diameter with 10 tips each, keep revolving during a turn rather than locking up, so you do not leave a bare crescent at the end of every row. Nylon spacers sit between each star, which is the fix for the wobble that plagues some competing spike units under load.

The tray accepts added ballast, and several owners report good results on soil that had been watered. The 39.5 pound frame keeps it in towable-by-anyone territory, and the pictorial assembly manual is the clearest in the spike category, which matters when you are buying from a brand you have not heard of.

This is a spike machine, so it channels and does not core. On a pasture, a large garden plot, or the compacted lane between a barn and a gate, that is exactly the job you want. On a lawn you intend to overseed, a plug aerator leaves seed a better path into the soil.

Where It Earns Its Keep

Anyone with more ground than a suburb lot. Owners comparing it against hired aeration services like the economics, and the tow bar holds up over ground with stumps and gravel that would twist a lighter frame. The independently revolving stars also cut the number of passes needed in tight areas, which is where coverage usually gets missed.

Where It Falls Short

A smaller group of owners report bent hitch arms and bent spike tips after contacting rocks, and one review reports both tires separating from the wheels. Rocky ground is the failure mode to think about here: a spike unit that meets a stone at speed stops rather than rolls over. Keep the pass speed low and inspect the hitch arms after the first rocky session.

8. Yard Tuff 36 Inch Drum Spike Aerator – The Only Water-Ballast Machine in the Lineup

Every other machine here is a reel. This one is a drum, and that changes the mechanics: the 36 inch drum carries 78 steel spikes that rotate as the drum rolls, so penetration is a function of drum weight and ground pressure rather than spike geometry. The drum holds up to 24 gallons of water, which is a far easier way to add ballast than finding concrete blocks.

Long-standing owners on half-acre to acre properties fill the drum and combine aeration with mowing on the same pass, which is the practical advantage. The drum punctures to about 2.5 inches, deep for a spike machine, and it does it without uprooting turf the way a spike reel can on a tight corner.

It arrives in a wooden crate that doubles as storage, two grease points keep the drum rotating freely, and the empty unit is still light enough to pull by hand. If you want an annual spike pass without a separate implement trip, a drum is genuinely a different tool from a reel.

Plan around the weight. At 125 pounds empty, this is the heaviest machine in the roundup, and filling the drum with water adds more on top. Check your tractor’s tow rating with the drum full, and drain it before it sits over winter or the water will freeze and split the drum.

Best Used On

Half-acre to acre properties where the owner already mows with a tractor attachment deck and wants the same pass to do double duty. The drum pattern works well on straight and curved runs, and the puncture depth is enough to relieve surface compaction and open the thatch layer without taking soil out of the root zone.

Where Owners Complain

One review reports the crate arriving with no bolts, washers, manual or pin, so check the hardware before you leave the delivery point. The weight is the other issue: fully filled, this is a real load, and tight corners can pull up grass even though straight passes are clean.

9. Craftsman 36 Inch Tow Behind Spike Aerator – The Smallest and Simplest Option

For a small lawn, a rough quarter acre, or a first attempt at aerating before you commit to a larger machine, this 36 inch Craftsman does the simple version of the job. Nine galvanized steel spike disks cut small slits roughly 1.5 to 2 inches deep, and owners use it in combination with mowing passes to prep soil for overseeding.

The 10-gauge steel frame is heavier gauge than most units in this price range, and the adjustable universal hitch is the feature that earns its keep: it accommodates different tractor hitch heights, so you can fit it to an older lawn tractor or a newer zero-turn without hunting for an adapter.

Assembly is easy, which is a bigger deal than it sounds. Several competing units in this category draw complaints about confusing or conflicting diagrams, and owners of this one report a straightforward setup with a hitch pin included in the box. The steel frame is the part most likely to still be there years later.

The honest limitation is width and capacity together. Thirty-six inches is the narrowest swath here and the 80 pound tray is the smallest, so a large property means more passes with less authority behind them. On heavy or rocky soil the tray empties quickly and the slits stay shallow.

Where It Fits

Small lawns, garden plots, and anywhere you want a cheap annual spike pass without storing a large implement. If your storage space is tight, a 36 inch unit with an adjustable hitch is the least demanding machine in the roundup to own.

Where It Falls Short

Buyers on hard soil report that it needs substantial added weight to penetrate at all, and the poorly labeled instruction sheet slows the first assembly. The 36 inch width also means a full acre takes considerably longer than with any of the 40 and 48 inch machines here, so this is a small-yard tool rather than an acreage tool.

10. BlumeTrec 40 Inch Tow Behind Spike Aerator – A Solid Budget Spike Unit With a Useful Lever

This is the newest listing in the group with the smallest review base at 49 reviews, so we weighted the spec sheet heavily here. Ten galvanized 3-D tines with 11 irregular tips each rotate independently, which means they keep cutting through a turn rather than dragging one side. The irregular tip pattern is a design choice that helps the tine find soil contact instead of sliding on a smooth surface.

The side-control lever is a better placement than most. Sitting at the side of the frame rather than behind, it is reachable to switch between transport and working modes without dismounting, and the pin-style universal hitch has adjustable height so it fits riding mowers, lawn tractors and ATVs.

Owners with a damp lawn report it digs in well for overseeding, and the 110 pound steel tray accepts old car batteries or cinder blocks for extra bite. Tools and gloves are included in the box, and the illustrated manual keeps assembly to roughly an hour for most people.

Water the lawn before you use it. In dry soil, reviewers report shallow holes and at least one owner saw only a quarter inch of penetration with no useful effect. The critical review on wheels is fair too: once the tray is loaded, the two 8 inch rubber wheels are the light-duty point in the machine, so keep speed low on uneven ground.

What You Get for the Money

A 42.5 pound frame, a 40 inch swath, a 110 pound tray and a lever-operated transport mode, in a machine that fits under most shed doors. For sandy or loamy soil, and for a lawn you are seeding each fall, that combination covers the job without a heavy implement in the garage.

Where It Falls Short

Forty-nine reviews is a thin base for a recommendation, and the critical reports are consistent: shallow holes in dry conditions and light-duty wheels under ballast. If your soil is clay, spend up for a machine with a 150 pound or larger tray and a rotating tine section design, because that combination is what produces visible results in heavy ground.

Will It Fit Your Riding Mower? Hitch Types and Tow Capacity

Start with your hitch, not the aerator. A standard drop-pin hitch uses two pins set into the tractor’s rear drawbar and works on most lawn tractors with zero parts. A clevis hitch with a single pin is the other common pattern, and the Brinly plug models use it, with owners confirming it reaches lawn tractors, most zero-turn mowers and ATVs. A 2 inch rear receiver on a zero-turn needs an adapter bracket, because there are no pins to drop into.

The r/lawncare question that comes up constantly is whether a universal hitch fits a zero-turn with a receiver. The answer is that most do not, out of the box. Measure the receiver diameter and the height from the ground to the bottom of the receiver before you order, and confirm the aerator’s pin spacing against the spacing between holes in your mower’s drawbar.

Then check tow capacity. A theLawnForum user constrained an entire search to aerators under 400 pounds total because of a John Deere Z970R max tow rating, and that constraint is correct for a reason. The rated figure covers the implement, all ballast, and anything else in tow, so a 175 pound tray on a 94 pound frame leaves 131 pounds of headroom on a 400 pound rating. Add a trailer and you can be over the limit, which stresses the transmission and the hitch hardware rather than the aerator.

You will find the rating in the mower owner’s manual under towing or trailer limits. If you cannot find it, the safe approach is to keep the total load under a quarter of the tractor’s weight and stay well inside the lowest published figure. Tow-bar height matters too: too high and the aerator lifts the tractor’s rear, too low and the tines drag on inclines.

Plug vs Spike Aerator: Which One Your Lawn Needs

A plug aerator removes soil. Hollow coring spoons lift 3/4 inch cores to the surface, and the surrounding soil expands back into the hole, so the total pore space in the root zone actually increases. A spike aerator only punctures, opening a channel that closes again under pressure. University extension services consistently recommend coring for compacted soil, and a small note of caution about repeated spike use is common in that guidance.

That is not an argument against spike units. A spike pass is lighter, leaves no mess, and works well on sandy or loamy soil that is only mildly compacted. The choice comes down to how hard the ground is and what you want afterward: coring before overseeding, spiking for routine annual maintenance.

Width is the second axis. A 36 inch machine needs more passes than a 48 inch machine and turns more easily. Swath width should match the shape of your open lawn, not just its size. If your yard is full of beds and trees, extra width buys you nothing and costs you maneuvering.

Weight Tray Capacity Is the Spec That Matters Most

Weight tray capacity is the number to compare, and the frame weight is almost beside the point. A machine weighing 60 pounds with a 150 pound tray can deliver 150 pounds of downward force to the soil. A heavier frame does not add to that figure unless the tray is rated for it. This is why an 82.8 pound Brinly with a 200 pound tray out-performs a 94 pound Agri-Fab with a 175 pound tray on hard ground.

The tiers in this roundup run from 80 pounds on the 36 inch Craftsman up to 200 pounds on the 48 inch Brinly. For firm but not severe soil, 100 to 110 pounds is usually enough. For compacted clay, 150 pounds and above is where you start seeing full-depth cores rather than surface slits.

Ballast is easy to find: concrete blocks, paving slabs, sandbags, or old car batteries. Distribute it evenly so the frame does not lean, and stay inside the tray’s rated figure. The Yard Tuff drum is the exception, since it takes water rather than blocks, which is a genuine convenience if you do not have 150 pounds of concrete lying around.

How Many Passes and How Many Holes per Square Foot

Extension guidance sets the target at 20 to 40 holes per square foot for a healthy result. A single pass with a 40 inch reel-style plug aerator lands far below that, which is why a single pass feels disappointing. Tine spacing matters as much as pass count, and 2 to 3 inch spacing is the range that works.

Here is the operating procedure we recommend. First pass at full ballast on a damp lawn, driving slowly enough that the frame does not bounce. Second pass offset by half the tine spacing so the cores interleave. Third pass at a right angle to the first two, which breaks the remaining grid pattern. Skip the third pass only on a small lawn that is already loose.

Speed is the variable people get wrong. Towing at a fast pace bounces the reel and skips punches, so a slower pass with the tray full beats a fast pass with the tray empty every time. If you are covering an acre, expect the job to take a couple of hours rather than a couple of minutes, and plan the route so you are not hauling a fully weighted machine around obstacles.

How to Aerate Your Lawn Without Ruining It

Before you pull anything, mow the lawn. Short grass gives the spoons a clear path and makes the pattern visible afterward. Then irrigate a day or two ahead so the soil is damp enough to core, and walk the property with a screwdriver to mark irrigation heads and any shallow lines you can find. Finally, check your tractor’s tow rating against the loaded weight of the aerator.

After you core, leave the plugs on the lawn. Owners repeatedly ask whether picking them up is necessary, and the answer is no: the cores break down within a week or two and feed the thatch layer, and the holes fill in on their own. Raking them up is pure extra work. One r/lawncare owner put it plainly, the holes fill in just fine in the end.

Seed and feed the same day or the next. Coring leaves open channels where seed and fertilizer reach the root zone, which is the whole point of doing it in the first place. Apply pre-emergent herbicide only after you aerate, never before, because coring opens the soil layer and pre-emergent applied ahead of it will not reach the weed seeds it is supposed to stop. Wait seven to ten days before mowing again so the new seed has a chance to set.

Frequently Asked Questions

Best Tow Behind Lawn Aerators for Riding Mowers: The Verdict

For most riding mower owners, the Agri-Fab 48 inch plug aerator is the pick, with the deepest tray in the mainstream tier and the largest owner record in the category. Pick the Brinly 40 inch instead if you want the best-rated corer and the least added weight to get a clean 3 inch core, and pick the Brinly 48 inch if your soil is heavy clay and your tractor’s tow rating allows a fully loaded tray.

Whatever you choose, load the tray, water the lawn first, and plan three passes. Those three habits do more for the result than the difference between any two machines on this list. Check the hitch type and your tow rating before the box arrives, and you will avoid the two problems that generate most of the complaints in this category.
