A piston lock system comprising: a cylinder, a rod receiver fixed to the cylinder, a piston slidably mounted to the cylinder, and a rod fixed to a free end of the piston and extending parallel to the piston to be located within the rod receiver. The piston and rod are movable relative to the cylinder and rod receiver between a retracted position and an extended position. A lock pin is mounted to the rod receiver and movable between a unlocked position in which the lock pin does not intersect a path of the rod, and a locked position in which the lock pin intersects the path of the rod and prevents the rod and piston from moving to the retracted position. Lock pins of multiple actuators can be connected to operate in unison.

An apparatus for actuating a rocking motion of a movable component including an adjustable length actuator, a lever whose angular position is controlled by the actuator, and a force transfer element attached to the movable component. The lever comprises a pair of oppositely placed pawls shaped so as to interact with the force transfer element for respectively actuating movement of the component in one of two opposite directions, when the lever exits a neutral positional range in which range any interaction between both pawls and the force transfer element is prohibited. The neutral range may be defined by a support plate positioned, shaped, and dimensioned so as to prohibit interaction between the pawls and the force transfer element. The displacement of the component in one direction may be larger than in the opposite direction.

A grain harvesting articulated combine of a forward crop processing power unit (PPU), a rear grain cart, and an articulation joint that connects the PPU with the rear grain cart and includes an auger assembly that moves clean grain from the PPU to the rear grain cart. Two pump circuits deliver power to a pair of hydrostatic motors located in the rear grain cart, one pump circuit hydrostatic motor driving the grain unloader assembly, the other pump circuit hydrostatic motor driving the ascending fill lift auger assembly, the drag auger assemblies, and the articular joint auger assembly. Power (inertia) can be harvested from auger assemblies not moving grain for startup or clog clearing of the other auger assemblies.

A dual conveyor assembly for a windrower includes upper and lower conveyors. Each conveyor includes an endless conveyor element and rotatable supports spaced along a longitudinal conveyor path and entrained by the endless conveyor element. The endless conveyor elements define vertically spaced opposed runs that define the longitudinal conveyor path therebetween. The opposed runs are operable to be driven together to move a flow of severed plant material along the path. At least one of the opposed runs is shiftable relative to the other opposed run in an upright direction, while the runs are driven together, such that the opposed runs remain in moving engagement with the flow of severed plant material as the amount of severed plant material passing between the opposed runs varies.

A crop unloader system comprising: an elevator assembly, a boom assembly, a flexible drive, and a tensioning assembly. The elevator assembly has a frame, an elevator drive and drive motor, and an elevator drive output. The boom assembly has a frame connected to the elevator frame at a boom pivot axis to rotate through a range of motion, and an unloader drive input. The flexible drive is operatively connected between the elevator drive output and the unloader drive input. The tensioning assembly has a tensioner link and a control link that are pivotally to each other and with one of the two links each pivotally connected to one of the boom and elevator frame. An idler wheel is on the tensioner link. The tensioning assembly maintains a tension load on the endless flexible drive within a predetermined range, throughout the range of motion of the boom frame.

A dust restrictor is provided for eliminating dust and dirt accumulation between surfaces. The dust restrictor includes at least one dust restricting element and an attachment means. The dust restricting element is disposed in a dust accumulating area of an arrangement. The attachment means is provided for fixing each of the dust restricting elements to the dust accumulating area. The dust restrictor can minimize an accumulation of debris, reduce the down time of a machine due to debris accumulation, and also increase life of bearing and motors operating a machine.

Pickup belt headers may include a ramp disposed in a gap formed between a first endless belt of a pickup belt assembly and a second endless belt of a transfer belt assembly. Fingers may be provided on the first endless belt, and the fingers may be deflected, such as by pivoting or bending, in response to engagement between the fingers and the ramp to avoid contact between the fingers and the second endless belt.

A chain and slat conveyor with first and second continuous chains and a plurality of slats. Each slat is connected to the first chain by a keyhole connection and to the second chain by a bolt or rivet which passes through a hole in the slat.

An agricultural harvester includes a chassis, a cleaning system carried by the chassis, a crop material elevator supplied with crop material that has passed through the cleaning system and has a first inlet and a second inlet, and an auger system supplying the crop material from the cleaning system to the crop material elevator. The auger system includes a first auger defining an auger axis that extends in a conveying direction toward the crop material elevator and is configured to supply crop material to the first inlet, a second auger defining a second auger axis that extends in the conveying direction, and a crop material conveyor configured to supply crop material from the second auger to the second inlet generally transverse to the second auger axis.
