Tow Behind Dethatcher vs Aerator: Which One Should You Buy?

Tow behind dethatcher vs aerator side by side

Figures are manufacturer stated for the example models, collected 25 October 2026.

Working width and tines

Width separates the two sides most clearly. The YITAMOTOR example covers 40 inches per pass with 20 spring steel tines, and the Vlaeng example covers 40 inches with 20 rust-proof tines. The Mantis Combo example covers a 15-inch swath with 60 spring-steel picks, and the Mantis 4222 example states no width, only four sets of tempered steel blades. Width alone does not settle the choice: a wide rake covers more ground per pass, while a narrow attachment covers less per pass.

Power and hitch

The YITAMOTOR example uses a universal hitch for riding mowers and ATVs, and the Vlaeng example uses a universal connector for mowers, tractors, ATVs and UTVs. The aerator examples attach to a Mantis tiller or cultivator, which is sold separately for each example. If you already tow with a mower or ATV, both dethatcher examples fit the fleet you own, and the Vlaeng example also lists tractors and UTVs; if you already run a Mantis tiller or cultivator, the aerator examples fit the tool you own.

What each side does

A dethatcher mainly rakes the surface. The Vlaeng example removes thatch, dead grass, compacted soil, pine needles and dry leaves, and the YITAMOTOR example removes thick thatch, dead grass and moss while performing shallow aeration. An aerator cuts into the soil. The Mantis 4222 example slices slits into the lawn to reduce soil compaction, and the Mantis Combo example pairs that soil cut with a dethatching pass from its picks. The combo is the overlap: it does both jobs in one attachment, at a narrower width than the tow behind examples.

Handling and weight

Weight figures describe one listing each. The Vlaeng example weighs 40.9 pounds, the YITAMOTOR example weighs 34.2 pounds, the Mantis Combo example weighs 17.5 pounds, and the Mantis 4222 example weighs 8 ounces. The dethatcher examples ride on wheels behind a tow vehicle, with a lift handle on the YITAMOTOR example and an adjustable handle on the Vlaeng example. The aerator examples ride on a tiller or cultivator, and neither Mantis listing states a tiller weight.

Upkeep

The dethatcher listings state their upkeep. The Vlaeng example asks for residue to be removed from the steel teeth after each use, and the YITAMOTOR example lists tines that are easily replaceable. The Mantis listings state no upkeep steps, and the combo listing states a limited warranty without a term, so the warranty scores zero here. Keep people and animals away during operation, as the Vlaeng listing directs.

Matching It to Your Property

• Match width to the lawn: dethatcher examples cover 40 inches per pass, while the Mantis Combo example covers a 15-inch swath.
• Check the hitch first: dethatcher examples use a universal hitch or connector, while Mantis examples need a compatible tiller.
• Raise the tines for transport over hard surfaces, as the dethatcher listings describe.
• Skip the Mantis Combo example on surface-rooted grasses such as Bermuda and Zoysia, per its listing.

The Acre Score explained

The Acre Score weighs five factors: performance, build, value, safety and warranty. A factor the listing does not state scores zero, which is why all four examples score zero for warranty. Only the YITAMOTOR example scores safety points, for its safety bar. How we pick explains the weights.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

Many owners keep a tow behind rake for spring and fall cleanup and a tiller attachment for compact patches. See the tow behind attachments for more towed tools.

FAQ: mowing large lots

Can a dethatcher aerate the soil?

Only in the limited way the listings describe. The YITAMOTOR example performs shallow aeration, and lowering the tines on the Vlaeng example allows for soil aeration. Neither listing describes the slit cutting the aerator examples do.

Do I need a tractor for a tow behind dethatcher?

No. The YITAMOTOR example lists a universal hitch for riding mowers and ATVs, and the Vlaeng example lists a universal connector for mowers, tractors, ATVs and UTVs. The Vlaeng listing asks you to check for a good spot at the back of your vehicle to attach it.

Will the Mantis attachments fit my tiller?

Check the model. The Mantis 4222 example fits Mantis tiller and cultivator models, while the Combo example fits the 7000 Series only and does not fit the XP, 3550 and 3558 models.

What width does each side cover?

The dethatcher examples cover 40 inches per pass, and the Mantis Combo example covers a 15-inch swath. The Mantis 4222 example states no width, so its coverage per pass is unclear from the listing.
