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.

A mower for turf or lawn includes a frame for use on a tractor, or to form a structure of a trailer, and a plurality of cutting units, at least six, generally disposed side by side, each cutting unit including at least one roller for rolling on the ground. The mower includes lift means linking the cutting units to the frame and configured for articulating the cutting units between a mowing position and a non-mowing position. In the mowing position, the lift means are configured for pressing the cutting units against the ground in order to distribute, at least partially, the mower's weight on the ground via the rollers of the cutting units. The mower includes lateral articulated beams linking the cutting units. The beams are foldable inwardly and forwardly.

A header including a cutter bar configured to cut crop for harvesting and a header frame supporting the cutter bar. A transport assembly is operatively connected to the header frame. A support arm is rotatably coupled to an axle of the transport assembly and is pivotably coupled to a mounting frame coupled to the header frame. A cam linkage is disposed at the support arm to provide a mechanical advantage for an operator when moving the transport assembly from a transport position to a harvest position. The cam linkage includes a lift assist device having a first end connected to the mounting frame and a second end coupled to a cam arm. Extension of the second end from the first end of the lift assist device applies the cam arm to a cam surface of the support arm to move the transport assembly to the harvest position.

A tool bar system is provided that is configured and arranged with weight distribution that inhibits the tool bar system from applying lifting forces to the rear hitch of the tractor that is pulling the tool bar. In one or more embodiments, the toolbar system includes a frame, lift wheels, a tool mount bar assembly having one or more forward sections and one or more rearward sections. The rearward sections are positioned rearward of lift wheels. Forward sections are positioned closer to the front of the tool bar system than the rearward sections, thereby reducing lifting forces at the front end of the tool bar system.

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 spray boom for an agricultural machine includes a first section having a first end and a second end and a second section having a first end pivotably coupled to the second end of the first section. The first section includes a first support member and a second support member disposed above the first support member. A centerline of the second support member is horizontally offset from a centerline of the first support member. Meanwhile, the second section includes a first support member. The spray boom may be configured in an extended position or a folded position. In the folded position, the second section is disposed above the first support member of the first section and adjacent the second support member.

A latch mechanism is used with agricultural equipment, such as a mower, for securing the header of the mower to the tongue during transport. A pivoting catch is mounted on the trail frame on which the header is mounted. A receiver for the catch is mounted on the tongue. During mower transport the catch is biased into engagement with the receiver by a first spring and secures the header to the tongue in a parallel orientation. When the mower configuration is changed to operational mode the catch is disengaged from the receiver using a second spring attached to the catch. A cable attaches the second spring to a wheel arm of a field wheel. Deployment of the field wheel into the operation mode draws the cable and second spring into tension, overcoming the biasing force of the first spring and pivoting the catch out of engagement with the receiver.

Systems, methods, and apparatus for shifting weight between a tractor and toolbar and between sections of the toolbar, for controlling operative height of a toolbar and sections of a toolbar and for folding a toolbar between a work position and a transport position. A ground engaging wheel and an actuator are coupled to the toolbar. In one embodiment, a fluid control system is responsive to a command signal to modify the actuator pressure such that the actuator pressure corresponds to a desired pressure.
