Abstract

A baler for forming crop material into bales. The baler includes a plunger moved by a plunger subassembly to form the bale, a knotter mechanism for knotting twine that is pulled onto the bale, and a knotter control assembly for controlling the knotter mechanism. The knotter control assembly includes a drive sprocket rotatable about its axis in timed relationship with movement of the plunger, a clutch plate mounted to the drive sprocket, and a knotter shaft positioned coaxially with the clutch plate. The knotter control assembly includes an actuation subassembly for engaging and disengaging the clutch plate with the knotter shaft. Upon activation, the actuation subassembly engages the clutch plate with the knotter shaft to activate the knotter mechanism, for knotting the twine on the bale. The actuation subassembly subsequently disengages the knotter shaft and the clutch plate.
