ABSTRACT:
A tractor-drawn plow is carried at its left front end on a tractor via vertically shiftable hitch means and at its right front end on a furrow wheel linkage means providing for raising and lowering of the frame among transport, open-up plowing and normal plowing positions. The hitch means and furrow wheel linkage include separate hydraulic motors of the two-way type, and these are connected hydraulically in series, with provision for re-phasing, to insure substantial leveling of the frame during raising and lowering movement of the frame. Provision is made in the connection of the hitch motor to the hitch means for enabling limited retrograde movement of the hitch motor piston to a position covering the re-phase port after the hitch motor has extended to fully raise the frame. Further provision is made in the furrow wheel linkage enabling lowering of the frame to either open-up plowing position or normal plowing position by retraction strokes of the same length of the furrow wheel motor.
