Outrigger lockup

Claim 1

In an outrigger lockup the combination of a pneumatically operated cylinder activating a mechanism securing a stub affixed on a pivotable outrigger supported on an agricultural equipment, said cylinder being connected to an air hose leading from an air tank and air compressor mounted on a tractor, said outrigger lockup eliminating need of manual locking by an operator to leave a tractor seat and walk around an upright outrigger before it is locked, said mechanism comprising a U-shaped loop pivotally secured at one end to a stationary frame of said agricultural equipment, the other end of said loop releasably hooking around said outrigger stub, a longitudinal center of said loop pivotally engaging a longitudinal center of a lock latch, an end of said lock latch being pivotally connected to a spring loaded piston rod of said pneumatic cylinder, a rear end of said cylinder being pivotally supported on said stationary frame, said stationary frame including a locking recess into which an opposite end of said lock latch is receivalbe, a first stop integral with one side of said recess so to form a corner in which said lock latch opposite end abuts when said loop is in a locked position around said stud, and a second stop being integral with said loop, whereby when said piston pushes said lock latch said opposite end of said lock latch is pivoted outward of said recess and abuts said second stop so that continued push of said piston causes said lock latch to roll around said second stop, thus pivoting said loop therewith and lift it from around said stud.
