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.

A reversible one-way disk plow comprising:
- (a) an elongated frame member having front and rear end sections, said frame member including a hitch attached to said front end portion for towing said implement;
- (b) transport wheels carried by said frame, said wheels being movable between raised and lowered positions, wherein said wheels are adapted to support said implement for transport when said wheels are in said lowered position;
- (c) plow means comprising a plurality of disks carried on an elongated shaft;
- (d) an elongated carrier;
- wherein said disk plow means is carried by said plow carrier;
- wherein said plow carrier is pivotable in a horizontal plane with respect to said frame member;
- (e) an arcuate track member secured to said frame member;
- (f) carriage means secured to said plow carrier and being carried by said track member;
- wherein said carriage means is movable along said track member;
- (g) a plurality of gauge wheels carried by said frame member, said gauge wheels being adapted to control the depth of said disk plow means in the ground when said transport wheels are in said raised position;
- (h) control means for controlling movement of said transport wheels between said raised and lowered positions and for moving said carriage means along said track member to change the angle of said disk plow means relative to the longitudinal centerline of said frame member;
- wherein said control means comprises a first and second control means, wherein said first control means comprises a hydraulic cylinder which is adapted to raise and lower said transport wheels;
- and wherein said second control means comprises a plurality of hydraulic cylinders which are adapted to raise and lower said gauge wheels and move said carriage means along said track member.
