Mechanism for automatically lifting a trailer drawbar support

A trailer (10) adapted to be coupled to a tow vehicle and including a frame (18) including a drawbar tube (22) defining a longitudinal axis. The trailer includes a drawbar support pivotally coupled to the drawbar tube and rotatable relative to the tube about an axis parallel to the longitudinal axis. The drawbar support is biased toward a substantially horizontal orientation. A sliding member (120) is receivable in the tube and is configured for movement along the longitudinal axis in response to movement of the tow vehicle. A latch member (64) is connected to the sliding member. The latch member is configured to move in response to movement of the sliding member from first position wherein the drawbar support is retained in a substantially vertical orientation to a second position wherein the drawbar support is free to rotate toward the substantially horizontal orientation.
