发明名称 Plow
摘要 A plow has coupling members at its forward side for connection to a multi-point hitch of a tractor. Furrow slicing members at the front form furrow slices which are elevated to furrow turning drums during operation. The furrow slices are turned about their longitudinal axes and deposited to the rear by the rotating drums. The drums are mounted on rollers and driven preferably by a hydraulic motor to rotate about upwardly and forwardly extending axes at variable speeds so that the angle through which each slice is turned can be adjusted depending on the soil condition. Projections within the drums turn the furrow slices which can be inverted and deposited to the rear. Also, an upper guide roller or auger can be located above the drums to guide and/or laterally displace the slices as they enter the drums.
