Abstract
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.
