Abstract
A lock cylinder for a backhoe slide frame which provides for a positive lock of the slide frame in selected positions is described. The slide frame is supported on two generally horizontal rails that are vertically spaced, and the lock cylinders mount between the vertically spaced rails. The lock cylinders each have a piston that acts to hold the slide frame seated against the upper one of the rails. The piston also provides a wedging action on at least one rail to hold the slide frame from fore and aft movement relative to the rail.
