A lock assembly includes a housing, a lock shaft, a reset shaft, and a transfer gear. The lock shaft is disposed partially within and extends from the housing and is movable between a lock position and an unlock position. The reset shaft is disposed at least partially within the housing, is spaced apart from the lock shaft, and is movable between a first position and a second position. The transfer gear is disposed between, and engages, the lock shaft and the reset shaft, and is configured to transfer motion between the lock shaft and the reset shaft. When the lock shaft moves from the lock position to the unlock position, the reset shaft is moved from the first position to the second position, and when the reset shaft moves from the second position to the first position, the lock shaft is moved from the unlock position to the lock position.

A wheel locking apparatus for locking the movement of a wheel assembly, said apparatus including an actuating means and a locking assembly. The locking assembly can include at least one locking arm. The actuating means can be configured to extend a locking arm from a first position to a second position. The locking arm is actuated into the second position to engage an aperture of the wheel assembly thereby locking the wheel assemblies. A locking arm having a locking pin portion that can be located at the second end of the locking arm. The locking pin portion can have a cavity wherein a portion of the locking arm fits within the locking pin portion. A biasing means can be located within the cavity and allow the locking pin position to move along a linear axis when a compressive force is applied to the end of the locking pin portion.

A hood lifting actuator according to various implementations includes a piston, a locking ring, and a housing including a protrusion. The housing further includes a distal end, the distal end defining a distal end wall, wherein the locking ring is retained between the distal end wall and the protrusion prior to actuation of the actuator. The piston travels from a retracted position to an extended position. In the extended position, the hood lifting actuator lifts a portion of a vehicle hood into an elevated position. In response to a force urging the piston from the extended position toward the retracted position, such as a person impacting the portion of the vehicle hood, the locking ring engages the protrusion and the piston, thereby locking the piston in a locked position.

An actuator assembly for moving an implement attached to an agricultural vehicle. The actuator assembly includes an actuator comprising a longitudinal axis, a cylinder extending along the longitudinal axis, and a piston rod extending from the cylinder along the longitudinal axis and that is configured to be attached to the implement at a connection point. A safety stop is pivotably attached at the connection point and is movable between a deployed position where the safety stop is configured to block retraction of the actuator, and a retracted position where the safety stop is not configured to block retraction of the actuator. The safety stop is configured to rotate with respect to the actuator about a first rotational axis that is orthogonal to the longitudinal axis, as well as a second rotational axis that is orthogonal to both the longitudinal axis and the first rotational axis.
