The Land Pride RTR20 Series Rotary Tillers are just right for home gardening, landscape work, vegetable farming, food plot maintenance, and light commercial use. The RTR20 features a reverse tilling action for tough conditions and turns up hard packed ground, leaving a perfect seedbed for gardens and grass.The reverse action "sucks" the tiller into the ground, which prohibits the tiller from "walking" on hard ground. It also incorporates spring loaded "sifting" rods behind the tines to help bury large rocks and debris. The reverse action of the rotor brings material up and over the top. Rocks and vegetation cannot get through the sifting rods so they fall first. Soil continues to get sifted before it falls, building a layer of large to small dirt clods burying the rocks and vegetation.
