The self-propelling Seedbed Tilther is designed to incorporate amendments (e.g., compost, fertilizer) and chop up/mix down the previous crop's roots to create a level, 2-inch-deep, 15-inch-wide seedbed that's ready for planting or transplanting. Made of stainless steel and aluminum with oiled ash handles, the Tilther is powered by a rechargeable drill (1/2-inch chuck size required, 18-volt or more battery pack recommended).
