driven pump (2). The fluid reservoir (3) is shared with the main hydraulic system. The steering wheel (4),

which is mechanically linked to the main steering gear (1), rotates a gear that positions a spool in the main

steering gear. This motion is hydraulically transmitted to a piston in the slave gear (5) causing it to follow

the rotation of the main gear. The main gear pitman arm (6) is mechanically connected to the slave gear

pitman arm (7). These pitman arms move the steering mechanism on the front axles (8) left or right causing

the vehicle to steer left or right.
