Best 40 Inch Tow Behind Lawn Aerators (2026)

The Agri-Fab uses 24 galvanized, sharpened coring knives that lift small plugs of soil as the unit rolls. Removing cores relieves compaction in a way that spikes cannot, because spikes push soil sideways and can pack it tighter. The plugs break down on the surface and return organic matter to the lawn.

A single lever raises the knives for transport and lowers them to work, and the 10 by 3 inch pneumatic tires roll smoothly over uneven ground and towing. The handle folds for storage, a real convenience in a crowded shed.

Unlike the generic listings here, it is made by an established brand in the US, which matters for parts and answers. Rinse soil from the knives, keep tires inflated and sharpen or replace worn knives. It lists no weight tray capacity, so check that you can add ballast if your soil is hard.

The MAXSA uses hollow heat-treated steel tines that pull plugs up to 3 inches deep, deeper than the 2 inch figures listed for the Brinly and VEVOR. That depth reaches more of the root zone, where compaction hurts most. A 100 pound weight tray lets you add ballast to push tines into firm soil.

Its 10 inch pneumatic tires and a lift handle make transport easy. Compared with the Agri-Fab, it states its depth and ballast numbers, but it comes from a newer, less established listing.

As always, tow it only with a machine that can pull the load, and ballast in small increments. Wash soil off the tines and check hardware. It suits lawn owners who want a stated 3 inch core.

The Brinly is a combination tool: 8 inch steel star tines with 132 tips perforate the soil while a steel hopper drops seed, fertilizer or lime in the same pass. Spreading while aerating works because the material falls into fresh holes, which improves seed contact. Its 1.74 cubic foot hopper holds about 100 pounds.

Because it uses stars with tine tips, it is a spike-style aerator that reaches about 2 inches and does not pull cores. That makes it less effective on heavy compaction than the Agri-Fab or MAXSA, though it saves a pass when overseeding.

An adjustable stop on the flow control sets the spread rate and a 75 pound weight tray adds penetration. Clean the hopper after fertilizer, since it can corrode. Assembly takes under 30 minutes. It suits owners who overseed.

The JFHID offers the largest stated ballast capacity here at 230 pounds, more than double the MAXSA's 100 pounds and the Brinly's 75. More weight drives tines deeper in dry or compacted soil, which is the main reason aerators underperform. Galvanized steel tines and an adjustable height with a lock let you set working depth.

The listing describes itself as both a plug aerator and a rolling spike aerator, so confirm tine type before buying; it is hard to be sure which action you get. Its 8 inch tires are smaller than the 10 inch ones on the Agri-Fab and MAXSA, which roll a little rougher.

Never load more than your tractor can tow. Rinse soil off tines, check bolts and store dry. It suits owners who need heavy ballast.

The YITAMOTOR is a plain 40 inch plug aerator with 24 tines, inflatable wheels and an adjustable handle. The tine count matches the Agri-Fab's 24 knives, so core density is similar. Inflatable wheels roll more smoothly than solid plastic ones.

The listing gives little detail on depth, ballast capacity or materials, so it is the hardest of the group to verify. That makes it a cheaper bet, not a spec-proven pick.

Check for a weight tray before buying, since you will want to add ballast. Wash the tines, keep tires inflated and check bolts. It suits budget buyers who accept limited data.

The BlumeTrec is a spike-style aerator with 10 galvanized 3D tines, each carrying 11 irregular tips that rotate independently. Independent rotation helps the spikes follow the ground. A 110 pound tray holds ballast for deeper penetration.

A side control lever switches between transport and working mode, and the pin-style hitch attaches quickly. It is a simple choice for loose or sandy soils where spiking is enough.

Spike aerators do not remove cores, so do not expect the same compaction relief as the Agri-Fab or MAXSA. Keep tines clean and dry. It is a light-duty option.
