A releasable locking mechanism for holding a boom in a stored position on a support consists of a latch pivotally supported on the boom and normally held in a first position with a pin carried by the swing tower and aligned with the latch. The pin and latch are positioned such that movement of the boom to the stored position will automatically pivot the latch and produce an interlocking relationship. The release mechanism consists of first and second pivotally interconnected elements, one of which is supported along the pivot axis for the swing tower on the vehicle and the second element having a control member extending therefrom to the operator\s station. A universal connection is provided between the control member and the second element, and is located along the vertical pivot axis for the swing tower.

In a vehicle having a operator\s station and an implement frame supported thereon with a boom pivoted on said frame and movable between transport and working positions, and releaseable latch means for locking said boom in said transport position on same said frame, said releaseable latch means comprising: pin means fixed to said frame at a location horizontally spaced from the pivot for said boom; a generally U-shaped latch having a pair of legs extending from a bite portion with said legs pivoted on said boom about a generally horizontal pivot axis spaced from the pivot for said boom and disposed towards said pin means such that said bite portion and legs cooperate to define a open space for receiving said pin means when said boom is in its transport position; biasing means, linking said boom with said latch, for normally maintaining said latch in a first position where said pin means is received within said open space when said boom in its transport position and for accommodating movement to a second position under the influence of said said pin means while said boom is moving to said transport position and for returning said latch to said first position when said open space is aligned with said pin means; unlatching means, fixed to said frame, for pivoting said latch from said first position to said second position, said unlatching means including a first element secured to said implement frame, a second element pivoted on said first element, and means, between said first and said second elements, for normally maintaining said second element in a first position, said second element and said latch having overlapping portions adapted to engage each other when said second element is in its first position and said latch is in its first position; and a control member connected to said second element and extending to said operator\s station for pivoting said second element from said first position to its second position, whereby with said boom raised to its transport position and with said latch and said second element in their first positions, said latch is freed from said pin means through the operation of said control member by pivoting said latch to said second position whereupon said boom is free to pivot away from said transport position to a working position.
