Abstract
A cotton module builder has a hydraulic cylinder which extends far above the top of the builder in operating position. The cylinder is latched in the upper position so that it may be lowered when the module builder is moved. A hook on the cylinder is engaged by bails upon a toggle lever so that the latch will not release the cylinder unless the cylinder is in a relaxed condition.
