Sensing system Ground speed sensor - Overview (C.20.B.95.80 -
C.10.A.10)
The ground speed sensor B-17 (1) is located on the top cover of the transmission, positioned above the differential
ring gear. The sensor is connected (X087) to the lower frame (LF) harness at (2), and provides an input to
the CCM2 module at connector X017 pin J3-14. The ground speed sensor B-17 circuit is also monitored by the
CCM2 module; in the event that a fault occurs with the sensor itself or the wiring to the sensor, a fault code will be
displayed to the operator.

The input from the ground speed sensor B-17 supports several functions, such as:
ground speed readout on display.
•
prevents activation of the transmission shift motor M-02 when the value from the sensor is above the threshold
•
value. This avoids gear shifting when the gearbox has components that are in motion.
automatic reel speed synchronization with ground speed.
•
automatic feeder speed synchronization with ground speed.
