A riding lawn mower having an adjustable cutting width has at least one front wheel, a plurality of rear wheels, a frame extending from the at least one front wheel to the plurality of rear wheels and a plurality of cutting decks, each cutting deck comprising a cutting blade. A motor is supported by the frame and configured to drive the cutting blades of the cutting decks. A support configured to couple the cutting decks to the frame. The support is configured to extend at least one of the cutting decks laterally from beneath the frame to adjust a cutting width provided by the blades.

In one embodiment, an in-line tandem axle assembly comprising: a tandem wheel arm; a pair of wheel connecting assemblies, each comprising a hub and a spindle; a pair of mounts coupled respectively to the pair of wheel connecting assemblies; a pair of wheels 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 of equal length pivotably mounted to the pair of mounts and pivotably mounted to the tandem wheel arm.

An agricultural implement includes a frame including a center section and a first wing section and a second wing section flanking the center section. The first wing section and the second wing section are configured to move relative to the center section during transitions between a folded position and an unfolded position. The agricultural implement includes a first rigid tube assembly disposed on the center section having a first set of rigid tubes and a second set of rigid tubes, a second rigid tube assembly disposed on the first wing section, and a third rigid tube assembly disposed on the second wing section. The agricultural implement includes a structural support configured to enable movement of the first set of rigid tubes and the second set of rigid tubes relative to the center section and each other during the transitions between the folded position and the unfolded position.

Systems, methods and apparatus are provided for managing implement weight. In some embodiments, a position sensor is used to determine a position of the wing section and a downforce applied to the wing is modified in order to lower the wing section. In some embodiments, the position sensor indicates the position of a wing wheel assembly of the wing section. In other embodiments, the position sensor indicates the position of a center wheel assembly of a center section of the implement.

A farm implement having rotatable wings rotatably connected to a main carrier and also having a folding bar linkage, which folds as the corresponding wing is rotated into a stowed position and extends as the wing rotates into a deployed position. A fixed length control bar rotatably linking a tow bar of the folding bar linkage to the main carrier controls the folding and unfolding of the bar linkage as the wing rotates between the deployed and stowed positions.

An agricultural planter which provides an improved method for extending and retracting the wing boom and which has improved maneuverability is disclosed. A drive member is provided that drives one or more of the carrier wheels on the agricultural planter. The drive member may be, for example, a hydraulic motor or an electric motor. When a wing boom is extended or retracted between the transport position and the working position, a controller generates a command signal to the drive member to drive one or more of the carrier wheels forward or reverse, thereby assisting the draft links in retracting or extending the telescoping portion of the hitch assembly and in extending or retracting the booms. During operation, the controller may similarly generate a command to the drive member to drive one or more of the carrier wheels either in forward or reverse according to the operation of the towing vehicle.

A towable farm implement having a frame element having a field end, a fold gate, and an inner wing tow bar rotatably connected to the frame member. The farm implement having a wing having a wing frame extending from a center end to an outer end. The fold gate can be rotatable between a transport position in which the fold gate is parallel to the main carrier and a field position in which the fold gate is parallel to the main carrier. Rotating the fold gate into the transport position can pivot the wing about the inner wing tow bar into a parallel orientation relative to the frame member. Rotating the fold gate into the field position can pivots the wing about the inner wing tow bar into a transverse orientation relative to the frame member.

Disclosure herein are hydraulic systems and method of use thereof. The hydraulic systems can include a hydraulic cylinder and a manifold. The hydraulic cylinder can have a first end and a second end. The hydraulic cylinder can include a first port, a second port, and a third port. The first port can be located proximate the first end. The second port cane be located proximate the second end. The third port can be located in between the first port and the second port. The manifold can include a first valve and a second valve. The first valve can be in fluid communication with the first port and the third port. The second valve can be in fluid communication with the second port and the third port.

A forward folding implement is provided. The implement includes a telescoping tongue to allow forward folding wings of the implement. At one end of the tongue are positioned transport wheels that are used to level the height of the frame during planting to keep the row units at determined heights of the single plant uniform depth, while also providing a support for the implement during transport of the implement. A transport wheel rotating assembly is provided to rotate the transport wheels about a pivot point such that the transport wheels will adjust the height of the implement, and also increase or decrease the length of the wheelbase between the tractor tires and the transport tires to increase the maneuverability and transportability of the implement both within a field and outside a field. The assembly includes a linkage and a cylinder connected to the implement.

An agricultural machine having a trailed chassis and a transverse bar in several portions extending substantially transversely to the direction of advance in the work position and extending substantially parallel to the direction of advance in the transport position, the transverse bar includes two portions able to be folded around a first respective articulation with a substantially vertical axis, each portion supports a seeder device made up of a hopper and a seeder bar. Each seeder bar is fixed on the corresponding portion using a second articulation with a substantially horizontal axis oriented parallel to the direction of advance in the work position.
