Improve your turf health. Maintain a healthy, lush lawn with the new Toro® Scarifier. De-thatching allows for healthy root growth by making water, air, and nutrients available to the soil. Featuring a durable steel deck and the power are what you need to pull out bad thatch and eliminate moss problems. Twice a year, use this scarifier, sometimes called a dethatcher, to remove the build-up of dead grass and weeds that forms on top of lawns and prevents moisture from reaching the roots.
