A cutting unit for an agricultural working machine and a method for adjusting the cutting unit are disclosed. The cutting unit comprises a support body, a cutting device on the support body, a front suspension arranged on the support body on a first half of the cutting unit and has at least one wheel that rotates about a front axle and a rear suspension on the support body on a second half of the cutting unit and has at least two wheels that rotate about a rear axle, the front suspension and the rear suspension being rotatable about a respective rotary axis relative to the support body so that the front and rear suspensions can each be transferred between a transport position and a working position. The front suspension and the rear suspension, when in their respective working position, are moved relative to the support body between a high position and a low position.

A crane arrangement includes a base, a pillar boom, a lifting boom, a folding boom, a lifting cylinder, and a folding cylinder. The lifting boom includes a first pivot point for connecting the pillar boom to the lifting boom, a second pivot point for connecting the lifting cylinder to the lifting boom, and a third pivot point for connecting the folding cylinder to the lifting boom. The lifting boom further includes a hollow cast connecting piece arranged at the first end of the lifting boom, in which connecting piece at least the first pivot point and second pivot point are arranged. The invention also relates to a corresponding work machine.

A transportable agricultural combine header includes a frame and a wheel assembly attached to the frame. The wheel assembly includes: (a) at least one spindle to which a wheel is configured to be mounted; (b) a rotatable arm connected to and extending from the spindle; (c) a frame attachment structure attaching the at least one spindle and the rotatable arm to the frame; and (d) a suspension system interconnecting the rotatable arm and the frame attachment structure for reducing stress on the frame as the agricultural combine header is transported.

An agricultural header for an agricultural vehicle includes: a header frame; at least one cutter carried by the header frame and configured to cut crop material; and a transport assembly coupled to the header frame. The transport assembly includes: a first arm coupled to the header frame and including a first wheel mount configured to mount a first transport wheel thereto; a second arm pivotably coupled to the header frame and including a second wheel mount configured to mount a second transport wheel thereto; and a cross arm coupling the first arm to the second arm. The cross arm is releasably coupled to the first arm such that the cross arm and the second arm are slideable and nestable with one another when the cross arm is uncoupled from the first arm.

A header including a front and rear wheel assembly, each assembly having an axle and two wheels. Each wheel assembly is coupled to the main body of the header by an actuating system having an actuator mechanism for actuating a swivel movement of the axle and the wheels to bring the wheel assembly to or from a road transport position. The front and rear wheel assemblies are equipped with tie rod arrangements for steering the header when it is transported on the road. The wheels of the wheel assemblies are operated as caster wheels. The tie rod arrangement of the front wheel assembly is coupled to a pivotable base connected to, or connectable to, a drawbar. The wheel assemblies have respective actuators which are synchronized so as to synchronize the position of the front and rear wheels.

A header that includes at least one support and transport wheel assembly having an axle and two wheels. The wheel assembly is coupled to the main body of the header by an actuating system that includes an actuator mechanism configured to actuate a swivel movement of the axle and the wheels, the swivel movement being configured to bring the wheel assembly to or from a position wherein the axle is transversal to the longitudinal direction of the header. The wheel assembly is equipped with a drawbar that is deployable from a storage position to a deployed position, wherein the movement of the drawbar between the positions is synchronized with the swivel movement of the wheel assembly.

A header including at least one support and transport wheel assembly having an axle and two wheels. The wheel assembly is coupled to the main body of the header by an actuating system that has two actuator mechanisms. When changing from the field mode to the transport mode, the first actuator mechanism brings the wheel assembly forward from a position behind the header, after the header has been lifted up from the ground. After completion of this first movement, a second actuator mechanism swivels the wheel assembly to a position that is transversal to the header, after which the header is lowered to the ground. The two-step approach enables the changeover between field mode and transport mode without pivoting or otherwise moving the header relative to the feeder. The wheel axle may be pivotably suspended from a frame element that executes the swiveling movement.

A header for a crop harvesting machine includes front and rear wheel arrangements that pivot about respective upright axis between a field orientation and a perpendicular transport orientation, while having respective suspensions arrangements movable between different suspended heights. A biasing spring provides lift assist to carry weight of the wheel arrangement during adjustment of the suspension elevation while being isolated from the suspension once set at any one elevation. The front wheel arrangement includes an anti-rotation latch that locks the front wheel in the field orientation automatically upon disconnection of a hitch arm. A second wheel of the rear wheel arrangement can be held in a raised position relative to a first wheel in a field orientation. Load bearing surfaces between the suspended rear wheels and the header frame abut one another when latching to the header frame to isolate the suspension from the header frame in the transport orientation.

The present disclosure relates to a steering system for an agricultural machine. The steering system includes a first and second wheel assembly. Each wheel assembly includes an axle assembly including an axle, wheels rotatably connected to the axle, and a double-action hydraulic cylinder. In some embodiments, the double-action hydraulic cylinder is configured to pivot the wheels in either direction to indicate a direction of turn. In some embodiments, the double-action hydraulic cylinder of the first wheel assembly is hydraulically linked in its operation to an operation of the double-action hydraulic cylinder of the second wheel assembly.
