ABSTRACT:
The invention is a hydrostatic device which converts rotary motion to oscillating motion for driving a sickle bar type mower by using a rotating cam plate to operate a rocker arm through a hydraulic coupling in the form of a pair of hydrostatic cylinders. The cylinders are continuously charged and due to valving openings in the pistons, the cylinders are continuously maintained in-phase with each other and the sickle bar which is being driven.
