Abstract
A multi-speed landing gear for a trailer includes a housing and a telescoping leg connected with the housing, and a gear assembly for extending and retracting the leg. The gear assembly includes a ring gear arranged to rotate about an axis transverse to the telescopic orientation of the leg member with the gear assembly configured to operate in a high speed setting and a low speed setting and automatically shift between the high and low speed settings, with an actuator selectively preventing or allowing rotation of the ring gear to enable the gear assembly to operate in the low speed setting or the high speed setting. The actuator may be connected to a shift member, with the actuator causing the shift member to selectively prevent or allow rotation of the ring gear by way of engagement of the shift member with the ring gear.
