Patent ID: 8561532

Claim:
An agricultural piston bale press, comprising: a pressing piston arranged in a bale chamber to form bales of crop material, a main driving mechanism to drive the pressing piston in an oscillating movement in the bale chamber; an intake device to take in crop material, and a stuffing device to stuff crop material taken in by the intake device and to load the stuffed crop material to the bale chamber; wherein the stuffing device comprises a feed passage and a stuffing mechanism, the stuffing mechanism comprising an arm supporting tines which arm is configured for movement along a stuffing trajectory to stuff crop material in said feed passage and a load trajectory to load stuffed crop material from said feed passage in said bale chamber; wherein said arm is movable by a first driving device to at least move the tines in and out of the feed passage and wherein said arm is pivotably supported by a fulcrum, the fulcrum being displaceable to selectively move the arm along the stuffing trajectory or load trajectory; and wherein the stuffing device comprises a second driving device to displace the fulcrum, and in that the second driving device is mechanically independent of the main driving mechanism.
