Abstract
An agricultural baler comprises a frame, a pick-up assembly for picking up crop material from a field and a baling chamber for receiving crop material from the pick-up assembly, the baling chamber having at least one movable wall portion. A plunger is mounted for reciprocating movement in the baling chamber for compression of the crop material therein, the plunger being driven by a gearbox which is affixed to the frame. A control unit adjusts the position of the movable wall portion in response to the signal from a load sensor, which is connected by a lever to the plunger gearbox for monitoring the reaction forces of the crop material on the plunger during the compression stroke. The lever arrangement includes a longitudinal pull member connected to one arm of the lever and a ball bearing mounted over the load sensor and connected to the other arm of the lever for precluding the effects of transverse or upward vibrations of the gearbox on the sensor.
