ABSTRACT:
A vehicle boom lock is disclosed for holding a boom assembly in a retracted transport position on an implement carrying swing frame. The boom lock includes a slotted coupling joint on the swing frame, and a deflectable cable assembly which extends cantileverably from the boom assembly for automatically interlockingly engaging the slotted coupling joint in response to pivotal movement of the boom assembly to the retracted position. A release mechanism can be manually manipulated from an operator station to conveniently disengage the cable assembly from the slotted coupling joint.
