The steering is of the hydrostatic type. If the pump fails to work, the steering can be operated in a closed cir-
cuit by means of the ‘’ORBITROL’’ distributor. The pump also operates the hydraulic circuit by means a priority
valve.
With a distributor, 2 position pick-ups, a switch and a pedal, the 2-wheel steering functions can be used.
