Abstract
A landing gear system including a landing gear actuator assembly arranged to selectably provide an increased torque output to a cross-shaft adaptor rotationally coupled to a cross-shaft of a trailer landing gear assembly. A rotational engagement mechanism is arranged to, in response to a remote signal, shift a rotational engagement mechanism to selectably couple the cross-shaft adaptor with a light gear set or selectably couple the cross-shaft adaptor with a heavy gear set. The landing gear actuator includes a slip-clutch assembly to dampen, reduce, or eliminate rotational shock caused when retracting or extending the legs of the landing gear system.
