Abstract: A combine harvester having a cleaning system for separating seeds from by-products, that includes a transmission having an annular member, that extends around a circular element of an eccentric device and is pivotable around said circular element, a second arm having a first end fixedly connected to the annular member, and a second end connected with a reciprocatable cleaner device of a second cleaner assembly, a first arm having a first end fixedly connected to the annular member, a first cleaner drive linkage has a first end pivotably connected to the second end of the first arm and a second end connected to a reciprocatable cleaner device of a first cleaner assembly, wherein the reciprocatable cleaner device of the second cleaner assembly and the reciprocatable cleaner device of the first cleaner assembly are reciprocatingly drivable by the cleaning system drive assembly in generally opposite directions.

Abstract: An agricultural harvester including a chassis and a header for gathering a crop and feeding it into the agricultural harvester. The agricultural harvester further includes a threshing and separating system, a grain cleaning system for separating grain from MOG, and a feeder housing for moving the crop gathered by the header from the header into the threshing and separating system. The agricultural harvester further includes a header tilt mechanism that allows the header to tilt in order to follow ground contours. The header tilt mechanism may use a face plate movably attached to the feeder housing. The header tilt mechanism includes at least one straight line linkage movably connecting the header to the feeder housing. The feeder housing or header tilt mechanism may be provided with hydraulic cylinders or pressure controlling or limiting arrangements.

Abstract: Agricultural square baler wherein the pivotable member is mechanically linked to the drive shaft by a linkage of the baler provided for mechanically pivoting the pivotable member in relation to the rotation of the drive shaft.

Abstract: An agricultural harvesting machine comprises a coupling for connecting a shaft to a driving element mounted for rotation about the shaft. The coupling provides a torque path between the shaft and the driving element which passes through both a lost motion connection and a shear bolt.

Abstract: A tensioning device is described for mounting between a knotter and a twine supply roll in a baler. The device comprises a spring biased tensioning arm 210 for taking up slack in the twine 216 and a clamp 220 for gripping the twine 216 at a location between the tensioning arm 210 and the supply roll. In the invention, the clamp 220 is coupled to the tensioning arm 210 in such a manner that the force applied by the clamp 220 to grip the twine 216 varies with the position of the tensioning arm 210.

Abstract: A square baler has an ejector system including a shuttle assembly mounted in a wall of the bale case for reciprocation parallel to the direction of movement of the bales in the bale case. A least one dog mounted on the shuttle assembly engages in the last bale in the bale case positioned nearest the discharge outlet and advances the bale incrementally in response to reciprocation of the shuttle assembly. A second shuttle assembly is mounted in a wall of the bale case for reciprocation independently of the first shuttle assembly. The second shuttle assembly has at least one dog to engage in the next-to-last bale in the bale case. By selecting which of the shuttle assemblies to activate, an operator may elect to eject only the last base in the bale case or the last two bales.

Abstract: A rotor reversing mechanism for a baler comprises a ratchet 12 mounted for rotation with the rotor, a pawl 22 carried by a reversing arm 16 for engaging the ratchet 12, a double acting hydraulic cylinder 32 for reciprocating the reversing arm 16 to cause the rotor to rotate in a reverse direction and means for disengaging the pawl 22 from the ratchet when the reversing arm is in a park position. In the invention, a spring 40 is provided for urging the reversing arm 16 towards the park position and the working chambers of the double acting hydraulic cylinder 32 are permanently connected to one another by way of a throttled passage 74.

Abstract: A square baler having a bale case within which crop is compacted by means of a plunger and a discharge outlet at one end of the bale case is provided and an auxiliary ejector system for advancing bales towards the discharge outlet independently of the movement of the compacting plunger. The ejector system comprises a shuttle assembly mounted in a wall of the bale case for reciprocation parallel to the direction of movement of the bales in the bale case. A least one dog mounted on the shuttle assembly engages in the last bale in the bale case positioned nearest the discharge outlet and advances the bale incrementally out of the discharge outlet in response to reciprocation of the shuttle assembly. In the invention, a second shuttle assembly is mounted in a wall of the bale case for reciprocation independently of the first shuttle assembly. The second shuttle assembly has at least one dog to engage in the next-to-last bale in the bale case.

Abstract: A square baler has a baling chamber and a bale chute arranged at the discharge end of the baling chamber. The bale chute comprises a rear portion that is pivotable about a horizontal axis to allow each bale to be lowered onto the ground without the bale toppling onto its end as it leaves the chute. The invention weighs each bale while the whole of its weight is supported by the rear portion of the bale chute.
