A header floatation system that includes a floatation mechanism which includes a first end and a second end opposite the first end, a first floatation adjustment array which includes at least a first contact point, a floatation mechanism mount which includes at least a second contact point, and a floatation mechanism fastener. The first end of the floatation mechanism can be mechanically linked to the floatation mechanism mount. Either the first floatation adjustment array or the floatation mechanism mount can include a third contact point. The floatation mechanism fastener can be positioned adjacent to, on, or through at least the first or second contact points aligning contact between the floatation mechanism mount and the first floatation adjustment array.

An agricultural machine includes a frame, and a lifting unit configured to vary a height of an operating unit with respect to a supporting surface for the machine. The lifting unit includes hydraulic cylinder with a liner and first and second pistons both slidingly housed inside the liner and arranged in series to define first and second chambers inside the liner, wherein the first and second pistons are controllable independently. The lifting unit includes a pressure stabilizer in fluid connection with the first chamber and that controls a pressure in the first chamber so that the first piston moves therein as a force generated on the first piston varies. A second control element for the second chamber carries out a volumetric control of the second chamber to control a position of the second piston regardless of a pressure inside the second chamber.

Various embodiments of a grounds maintenance vehicle are disclosed. The vehicle includes a frame and a control tower disposed at or near a rear end of the frame. The control tower includes a support structure that defines an interior space of the control tower and a nonplanar removable skin connected to the support structure. The removable skin includes a front side disposed over a front side of the support structure and a lateral side disposed over at least one of a left side or a right side of the support structure. A portion of at least one of the front side or lateral side of the removable skin is disposed above an uppermost surface of the prime mover. Further, the removable skin is adapted to be at least partially removed from the support structure to facilitate additional access to the interior space of the control tower.

An operator support for a grounds maintenance vehicle, the operator support including a platform, one or more isolator arms, and an isolator element. The platform includes a platform body and a platform arm extending from the platform body. The platform arm is pivotally coupled to a chassis of the grounds maintenance vehicle and configured to pivot about a platform pivot axis. The isolator element is coupled to the chassis of the grounds maintenance vehicle and configured to attenuate vibration transmitted from the chassis to the platform body through the one or more isolator arms. The one or more isolator arms are configured to isolate the platform.

A suspension for a mower includes a stationary part, a movable part, and at least one cutting unit. The moveable part is connected to the stationary part via a hydraulic actuator such that an actuation of the hydraulic actuator displaces the movable part in relation to the stationary part. Displacement of the movable part includes a vertical component of displacement of the movable part. At least one cutting unit is mechanically connected to the movable part.

An agricultural machine includes a hitching support, at least one tool or group of tools that can be transferred between an operational position and a raised position, at least one support arm that is connected to the hitching support via two joints and to the tool or group of tools at an assembly location, and a safety device for performing a safety movement under the effect of pressure. At least one first safety movement phase is carried out around the first joint or around one of the two joints. The safety device includes at least one guiding device to allow for a variation in a distance between the other of the two joints and the assembly location when the rearward rotation is carried out around the first joint.

A mowing machine has a cutterbar oriented transverse to a travel and working direction of the mowing machine and provided with first and second ends spaced apart from each other in longitudinal direction. First cutting members are rotatably mounted on a top side of the cutterbar and rotatably driven about a vertical axis by a drive assembly within the cutterbar. A joint and drive assembly is connected to the first end of the cutterbar. A lateral cutterbar section is connected to the joint and drive assembly and has a second cutting member driven by the joint and drive assembly. The joint and drive assembly has first and second holding elements mounted relative to each other such that pivoting of the lateral cutterbar section in a cutterbar plane of the cutterbar is enabled. The first and second holding elements are arranged in planes positioned at a minimal spacing above each other.
