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.

An agricultural machine includes two side units and a chassis that extends in a longitudinal direction and is equipped with two wheels, each side unit being fitted to pivot in relation to the chassis around a folding axis parallel to a median plane of the chassis. Each side unit includes a tool unit connected to the chassis by an arm and being able to occupy a work position in which the length of the tool unit extends transversely to the longitudinal direction. Each side unit is also able to occupy a transport position in which the length and width of the tool unit are parallel to the median plane. The machine includes a tilter articulated with the chassis around one tilting axis oriented transversely to the longitudinal direction, and in the transport position of the side units, each tool unit is closer to the median plane than the respective arm.

In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm (46); a pair of wheel connecting assemblies (44A, 44B), each comprising a hub (60A, 60B) and a spindle (58A, 58B); a pair of mounts (50A, 50B) coupled respectively to the pair of wheel connecting assemblies; a pair of wheels (52A, 52B) coupled respectively to the pair of wheel connecting assemblies, the pair of wheels separated by the tandem wheel arm and in a same fore-and-aft position; and plural pairs of parallel links (48A, 48B) of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

An agricultural implement includes a toolbar that extends transverse to a tongue when in a field use configuration. The toolbar can be lifted and/or rotated relative to the tongue to transition between a field use and a transport use. A lifting assembly includes one or more actuators and linkage systems to lift the toolbar attached thereto in an arced manner in moving from a field use configuration to a transport configuration. A rotating mechanism can also include one or more actuators to rotate the toolbar about a pivot member. An anti-rotation link includes a member is connected to the toolbar and can be positioned at least partially within a groove to mitigate rotation of the toolbar, such as during the lifting of the toolbar.

An exemplary form of mobile agricultural equipment generally includes a main frame, a wing frame, and a hinge mechanism. The main frame defines a track, and the wing frame has a roller rotatably mounted thereon. The hinge mechanism movably couples the main frame with the wing frame such that the wing frame is movable relative to the main frame between a first orientation and a second orientation. The hinge mechanism generally includes a sub-hinge plate pivotably coupled with the main frame, a first link pivotably coupled to each of the wing frame and the sub-hinge plate, and a second link pivotably coupled to each of the wing frame and the sub-hinge plate. The roller is configured to travel along the track during a portion of a movement of the wing frame between the first orientation and the second orientation to thereby provide support for the wing frame

An end wheel assembly for transforming an implement frame from a transport position to a field position is provided. The end wheel assembly can have an end wheel, a wheel pivot rotatably connected to the end wheel, a wheel member pivotally connected to the wheel pivot, at least one attachment bracket attached to the wheel member and pivotally attachable to the implement frame, a wheel actuator to raise and lower the end wheel assembly, and a guide plate. The guide plate can have a channel, a first end connected to the wheel member, and a second end connected to the wheel pivot. The channel can be positioned to receive a positioning member when the end wheel assembly is pivoted downwards and to rotate the guide plate causing the wheel pivot and end wheel to rotate relative to the wheel member and turn the end wheel outwards.

A hydraulic height control system controls all raising, lowering and folding movement of agricultural tillage equipment. The system includes a single hydraulic circuit utilizing non-rephase cylinders which allows for independent raising and lowering of the equipment frame sections and tool gangs. The hydraulic circuit also controls the folding of the frame wings between field and transport positions. Sensors monitor component positions. The hydraulic circuit also uses a common rail for providing fluid to the cylinders. The system achieves precise depth control in the high speed tilling agricultural environment by keeping the tilling components at the appropriate depth or operating position
