Abstract
A round baler includes bale forming mechanism and a crop delivery apparatus for delivering crop material to the bale forming mechanism. A clutch is provided for drivingly disconnecting the bale forming mechanism and delivery apparatus from the driveline while the tailgate is raised to discharge a wrapped bale. Engagement and disengagement of the clutch is controlled by a piston and cylinder assembly, and raising and lowering of the tailgate is controlled by a pair of piston and cylinder units. The baler is provided with a hydraulic sequencing circuit that connects the clutch assembly and the tailgate units to a common source of pressurized fluid. Moreover, the sequencing circuit controls fluid flow to the assembly and the units so that the clutch is disengaged before the tailgate is raised and the clutch is not re-engaged until the tailgate has been closed.
