Over time your lawn will accumulate a layer of thatch (old grass clippings, dead roots and other small debris). The Ariens Dethatcher combs thatch and clippings to the surface where they can easily be bagged or re-mulched providing you with a healthier lawn. Keep your lawn healthy by removing excess thatch build-up. This allows fertilizer and water to penetrate into the ground and get air to the plant roots.

Rated 5.0 out of 5.0 by Great product, but hard on the Mower This dethatcher is probably the best tool you will ever own. It works extremely well and will cut an all day job of back breaking labor into 2-3 hours. The amount of thatch removed by this product is amazing...easily 10+ bags for my 1/4 acre lawn...and I dethatch it every year. My only complaint about this product is that the bolts are rather cheap and can break easily. I snapped one of the tension bolts off the dethatcher unit from just slightly over tightening. However, it still works perfectly even though one of the bolts is missing a head, no issues at all. So, the product itself is well built...just not the bolts. It is also very difficult for the nuts to thread onto them. Thus, they are not machined well...which is probably what caused this problem in the first place. One should note that while this product does make the brutal task of dethatching with a hand rake much easier, it is still strenuous, especially if you need to go up hills. Your self propelling mower will not always help is much more difficult than mowing your will need to help push. This product will also tax the drive belt, cable, and friction disk on your mower. You will most likely need to adjust your cable after you use it for the first time. After 2-3 seasons of dethatching, I would assume based on my experience thus far, that you will need to replace your drive belt. However, it is a small price to pay for something that works so well. I have no regrets! April 30, 2013
