ABSTRACT:
A hydraulic system for a tobacco combine incorporates a single pump for driving a pair of tobacco leaf defoliators in contra rotating directions, and a pair of hydraulic motors for the take off conveyors in the same direction. Precise synchronization of the defoliator blades driven by the motors is assured by serially connecting the motors in the hydraulic circuit. A 50--50 flow divider provides equal hydraulic fluid flow to a pair of hydraulic motors, each driving portions of a first conveyor system, respectively, the fluid flows from these two motors being combined to drive a common second conveyor system.
