A press for producing bales of forage and the like includes a supporting structure provided with wheels, the supporting structure being adapted to support rollers and a collection and feeding device, at least one roller of the set of rollers being actuated by a hydraulic motor, the at least one hydraulic motor being actuated by at least one hydraulic pump.

An electrohydraulic system for a work machine includes a pump, a motor fluidly coupled to the pump, a subassembly driven by the motor, and a rate-control valve fluidly coupled to the pump and the motor. The rate-control valve is movable through a range of positions. A present speed of the motor is proportional to a present position of the rate-control valve. The present position of the rate-control valve is adjustable by varying a current supplied to the rate-control valve. The supply of current to the rate-control valve is adjusted based on the difference between the present speed of the motor and a target speed of the motor.

A bale wrapping apparatus for both inline and individual bale wrapping is described herein. The bale wrapping apparatus includes a bale wrapping mechanism configured to carry a plastic film around a bale when the bale is positioned in a bale wrapping space of the bale wrapping mechanism. The bale wrapping mechanism includes at least one movable tine that is configured to extend into the bale wrapping space to support the bale in the bale wrapping space when the bale wrapping apparatus is configured for inline bale wrapping and is movable out of the bale wrapping space when the bale wrapping apparatus is configured for individual bale wrapping. The bale wrapping apparatus also includes two powered rollers for supporting and rotating the bale in the bale wrapping space during individual bale wrapping. The two powered rollers are movable to configure the bale wrapping apparatus for inline bale wrapping.

A crank-operated packer mechanism includes a crank shaft including crank pins and crank arms. At least some of the crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced. The arms may, for example, be curved or hook-shaped. The crank shaft further includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings.

A conveying device for conveying crop material from a pick-up mechanism to a baler comprises a conveying channel having a base comprising an upstream base part and a downstream base part. The downstream end of the upstream base part is supported on a pair of first resilient mounting members and the upstream end of the downstream base part is supported on a pair of second resilient support members. The first and second resilient support members, in response to the force with which crop material is being urged by the feed rotor against the upstream and downstream base parts exceeding respective first and second predefined values, yield. This results in downward displacement of the upstream base part and the downstream base part to permit crop material to pass through the conveying channel.

An agricultural crop baler (20) includes a baling chamber (44), a crop pickup (26), and an adjustable partition mechanism (28). The crop pickup (26) is upstream from the baling chamber (44) to collect severed crop material and direct a flow of crop material toward the baling chamber. The partition mechanism is located between the crop pickup and the baling chamber to control the flow of crop material from the crop pickup to the baling chamber. The partition mechanism (28) includes a wall assembly (68) that at least partly defines a crop passage (76) extending along a crop-flow direction between the crop pickup (26) and the baling chamber (44). The wall assembly (68) includes a shiftable wall (74a, b) that is shiftable transversely to the crop-flow direction to adjustably vary the crop passage and thereby the flow of crop material to the baling chamber (44).

A shredding and baling apparatus provided includes a shredding assembly operatively connected to a baling assembly via a conveyor. A rotatable drum with cutting teeth spirally arranged along the drum is preferably centered within a lower portion of an intake hopper for cutting through material as it is fed into the hopper. Fixed cutting teeth are preferably arranged in a row or rows along each of the longitudinal sidewalls of the hopper, adjacent the cutting drum. A touch screen display and computer may be used in combination with sensors to monitor and control the shredding and baling operation, and a hydraulic system is used to drive the components. The shredding and baling assembly is preferably designed in an industrial size to handle high volumes of material and may be driven or transported from one location to another.

A crank-operated packer mechanism includes a crank shaft including crank pins and crank arms. At least some of the crank arms are shaped in a way that deviates from a straight shape to such an extent that the crank shaft is statically balanced. The arms may, for example, be curved or hook-shaped. The crank shaft further includes crank pins and crank arms assembled by a tapered spline connection. The connection includes tapered spline features on outer ends of the crank pins and in openings provided at outer ends of the crank arms, which interlock when the crank pins are inserted in the openings.

A pickup unit of an agricultural baler that includes a frame, at least one draper belt, at least one belt actuator operably connected to the at least one draper belt, a first auger and a second auger each being rotatably connected to the frame and located above the at least one draper belt, and a first and a second auger actuator respectively operably connected to the first and second auger. The pickup unit also includes an electrical processing circuit operably connected to and configured for adjusting the at least one belt actuator, the first auger actuator, and the second auger actuator so that a rotational speed of the at least one draper belt, the first auger, and/or the second auger is increased or decreased to evenly distribute the crop material as the crop material is transported to the bale chamber.

An agricultural machine includes: a machine frame; and a feeder system coupled with the machine frame and including a windguard assembly, the windguard assembly being configured for selectively occupying a first position and a second position by moving therebetween, the first position being associated with a normal flow direction of a crop material relative to the feeder system, the second position being associated with a reversal of the normal flow direction of the crop material.
