Cub Cadet TANK S Series: Hydraulic Drive & Steering System - Manual (Page 3)

SYSTEM OVERVIEW:
The steering system incorporated on the TANK-S Unit is a system that coordinates the steer angle of the front
wheels and the speed of the rear wheels when negotiating a turn. The front steering assembly is connected to
the drive wheel hydraulic pumps by a coordinated linkage system. As the front wheels are turned in a
direction, the speeds of the rear wheels are synchronized to match the exact speed required for the turn
created by the steer angle of the front wheels.
The hydraulic steering system consists of a pump, a valve located in the steering column and a cylinder
connected to the front linkage. Turning the steering wheel, rotates the control valve sending a calibrated
amount and pressure of fluid to the steering cylinder. The cylinder positions the front wheels for the desired
turn radius.
The drive system consists of separate RH and LH pumps and RH and LH drive motors. Mechanical linkage
from the front steering system and a manually operated foot pedal connected to the individual pumps control
the speed and rotational direction of the motors.
The system is supplied from a common reservoir and filter.
