Description of function

The ground drive hydraulics forward (B97) and backward (B98) highpressure sensors are installed in the pressure outlets of the ground drive variable displacement pump (211).The ground drive hydraulics forward highpressure sensor B97 permanently transmits the ground drive pressure to the ground drive module (A49). This signal controls the motor rpm and the swivel angle of the ground drive variable displacement motor (210).The ground drive hydraulics backward high-pressure sensor B98 permanently transmits the ground drive pressure to the ground drive module (A49). This signal controls the motor rpm and the swivel angle of the ground drive variable displacement motor (210).
