ABSTRACT:
A change speed gearbox for a combine or the like has a main clutch on its input shaft and a shift collar shiftable into alternate positions from a neutral position to establish different driving ratios in the gearbox. An electro-magnetic brake is engageable with the input shaft and is actuated only when the shift collar is in its neutral position and the clutch is disengaged. The brake circuit includes a relay switch that automatically opens a predetermined time after it closes, so that power is supplied to the brake only for a limited period when the clutch is disengaged and the gearbox is in neutral.
