Abstract: The invention is a land clearing rake that is typically mounted on a moldboard on a conventional bulldozer. The land clearing rake pivots about a shaft that is horizontally connected to the front of the moldboard. The rake is comprised of teeth connected to each other by heavy-duty plates between each of the teeth. The teeth may be arranged in one or more sections wherein the sections can be simultaneously raised or lowered by winches mounted on the moldboard. The winches are remotely controlled from the operator's seat. Thus, the land clearing rake is capable of being quickly raised or lowered by the operator while the earth moving equipment is moving back to prepare for another forward move. The ability to quickly transition between raking and grading modes significantly improves the efficiency of land clearing operations.

Abstract: A frame beam supports a plurality of plow bodies, the front plow body of which has a one-piece moldboard and is pivotable about an upwardly extending axis. Part of the moldboards of each of the following plow bodies is pivotable about an upwardly extending axis relative to the remainder of each such moldboard. Adjustment is made through rod systems from a common rod which is displaceable mechanically by a screwthreaded spindle or hydraulically by a piston and cylinder assembly. The latter adjustment is effected automatically in response to the tractive force required to drive the plow through the soil.

Abstract: 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 to rotate about upwardly and forwardly extending axes at preselected speeds. Projections within the drums turn the furrow slices which can be inverted and deposited to the rear.
