40" Dethatcher

Thatch is a layer of built-up organic material between the top growth of your grass and the roots. Some thatch is essential to protecting the roots, but too much can literally suffocate your lawn, creating a barrier keeping moisture and air from reaching the roots of your lawn. Read More >

Additionally, if you’re planning to seed, dethatching is an important prerequisite before spreading. Seed will often take root in thatch, not the soil, and will die quickly due to insufficient access to nutrients and water.

If your lawn has excessive thatch buildup, Brinly’s 40” Tow-Behind Dethatcher is the tool for you. Perfect for small to medium lots, this premium attachment gently combs old grass clippings, dead roots and other small debris to the surface where they’re easily bagged or re-mulched. The durable 20 independently flexing tines are 3/16” in diameter and feature a spring steel with triple coil strength. Need to cross the driveway? A single lever, accessible from your tractor seat, activates the 6” x 1.5” transport wheels. The dethatcher has three positions: transport, dethatch, and scarify.
