Abstract: A reversible one-way disk plow is described which includes a frame with transport wheels and an arcuate track secured to the frame. An elongated disk plow is pivotably supported under the frame, and a plurality of gauge wheels are carried by the frame. The plow can be selectively pivoted between first and second positions relative to the longtiudinal centerline of the frame. Hydraulic cylinders are used to pivot the disk plow, raise and lower the transport wheels, and raise and lower the gauge wheels.

Abstract: This combine manure-crushing and soil-mixing rotary machine adapted to be hitched to a tractor is provided with a tool carrier shaft operable at least at two different velocities, namely a higher speed for performing the manure-crushing operation and a lower speed for performing the soil-mixing operation; the change from one velocity and one mode of operation to the other is obtained by simply interchanging gear wheels and reversing the machine end hitched to the tractor.
