摘要： A baler includes a chamber having a fixed size that receives crops and houses a formed bale. A tailgate is connected to a frame and is movable between a closed position, for cooperating with the frame to delimit the chamber, and an open position, for discharging the formed bale. A conveying assembly delimits the chamber for imparting a rotating movement to the crops contained in the chamber, and has a first portion provided in the frame and a second portion provided in the tailgate. An actuator includes a closing chamber and moves the tailgate from the open position to the closed position upon receiving an actuating fluid in the closing chamber. A binder binds the formed bale, and a pressure sensor detects a control signal representative of a pressure inside the closing chamber of the actuator. A control unit generates an alert signal as a function of the control signal.

摘要： A towing apparatus for agricultural machines of the type of balers and round balers. The towing apparatus includes a first member, which can be coupled to the agricultural machine and is associated with a second member. The second member is in turn associated with a third member, which can be coupled to a tractor for towing the agricultural machine. Either or both of the first member and the second member is controlled by at least one respective actuator, for the movement of the agricultural machine at least partially independently of the advancement of the tractor.
