A mechanism is provided for engaging and disengaging the reverse operation of a feederhouse of a harvesting apparatus. The mechanism solves the problem of accurate engagement between the shift collar or driving element and the reverse gear, teeth or splines and the forward gear, teeth or splines of the feederhouse transmission. The mechanism comprises an actuator, electrically controlled, which loads or compresses a spring, wherein the spring exerts a shifting force on a shift shaft or shift fork of the gearbox which automatically moves the shift collar or driving element of the transmission into either a forward or reverse drive position when the gear, teeth of splines of the shift collar is aligned or meshed with the gear, teeth or splines of either the reverse or forward drive of the feederhouse transmission.
