摘要

PURPOSE:To enable a ridge-forming mulching operation preventing the treading of planted potato, sweet potato, etc., with the tire of a tractor, by attaching a high-ridge-forming mulching machine to a tractor in an offset state. CONSTITUTION:Potato or sweet potato is planted on a plowed, harrowed and leveled field. A high-ridge-forming mulching machine 19 is attached to a tractor in an offset state to carry out simultaneous ridge-forming and mulching operations. The treading of seed potato with the rear wheel 5 of a tractor can be prevented by this process, in contrast with conventional method, because the high-ridge-forming mulching machine 19 is attached to the tractor in an offset state.
