A header for an agricultural harvester includes: a header frame; a flexible cutterbar carried by the header frame; a plurality of flex arms coupled to the cutterbar; and a flex arm drive assembly coupled to at least one of the flex arms and configured to selectively, linearly displace the at least one coupled flex arm in a vertical direction relative to the header frame.

According to an embodiment of the disclosed subject matter, a lift assembly for a lawnmower can include a mower housing configured to house blades for cutting vegetation. A frame can be located above the mower housing, the frame including two longitudinal extending frame members, and at least one pivot bar extending between the two longitudinal extending frame members. A linear actuator can be located adjacent the frame members and connected to the pivot bar such that actuation of the linear actuator causes the pivot bar to rotate about a rotational axis of the pivot bar. At least one cam can be connected to the pivot bar so as to rotate with the pivot bar, the cam including a mower housing attachment element that supports the mower housing such that rotation of the cam varies a distance between the frame and the mower housing.

A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.

A combination flex and rigid control system for a header of an agricultural harvester includes ground proximity detection arrangements for both rigid mode and flex mode operation of the header. The ground proximity detection arrangements are each coupled to the same sensor shaft by way of a sensor arm that is moved by either of the ground proximity detection arrangements.

A ground height gauge assembly is provided. The ground height gauge assembly includes a shaft configured to be rotatably coupled to the header. The ground height gauge assembly includes a first arm coupled to the shaft and configured to simultaneously rotate with the shaft, the first arm defining a first length. The ground height gauge assembly includes a second arm pivotally coupled to the shaft and defining a second length, the second arm configured to be mounted in a first position and a second position. The second length of the second arm is dimensioned greater than the first length of the first arm. In the first position the second arm is configured to rotate independently of the first arm. In the second position the second arm is configured to be coupled to the first arm such that rotation of the first arm simultaneously rotates the second arm.

A rigid height control system configured to be coupled to a header includes a rigid arm pivotally coupled to a shaft. The rigid arm includes an upper end and a lower end, wherein the lower end is configured to engage a ground surface. The rigid height control system includes a metal channel guide coupled to the shaft and a magnet embedded within the rigid arm adjacent the upper end. The magnet is configured to keep the rigid arm attached to the metal channel guide via a magnetic force so that the lower end engages the ground surface when the agricultural harvester travels in a forward direction. The magnet is configured, when the agricultural harvester travels in a reverse direction causing a force exerted by the ground surface on the rigid arm to exceed the magnetic force, to allow a release of the rigid arm from the metal channel guide.
