Abstract: A binding device for a square baler for knotting a strip-shaped binder which is provided for binding a pressed bale. The binding device comprises at least one knotting device driven by a knotter shaft, a needle rocker pivotable about a pivot axis extending parallel to the knotter shaft on which binding needles are positioned, and a drive unit that has a shiftable gearbox which is driven by a drive shaft and is configured to drive the at least one knotting device and the needle rocker when a binding operation is triggered. The shiftable gearbox comprises a gearbox housing in which components of the gearbox and a triggering device for triggering the binding operation are positioned.

Abstract: A square baler has a press channel, a knotter arranged on the press channel, a blower and flow guide element, which is moveable between a first position, in which the flow guide element directs a blowing air stream of the blower onto the knotter, and at least one second position, in which the flow guide element directs the blowing air stream past the knotter.
