When the range output gear is being driven its gearset rotates to drive the rear wheels. See Range Gear Operation . The front wheels can be driven by engaging the MFWD shift collar (A) with the rear gear (B) of the range output gear and the MFWD output shaft (C).
When the shift collar (A) is in the forward position it does not engage the range output gear and the internal splines of the shift collar do not engage the splines (C) of the MFWD output shaft. The machine operates in a rear drive mode.
When the shift collar is moved rearward it engages the range output gear and the shift collar engages the splined MFWD output shaft which rotates and drives the front wheels through the MFWD shaft and front axle gears.
