The invention relates to an agricultural piston bale press. This press includes a pressing piston arranged in a bale chamber, an intake device to take in crop material, and a stuffing device, wherein the stuffing device includes a feed passage and a stuffing mechanism, the stuffing mechanism includes an arm supporting tines, 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. The stuffing device includes a second driving device to displace the fulcrum, and in that the second driving device is mechanically independent of the main driving mechanism.
