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 wedge-shaped tongue upon the carriage of the builder is hydraulically moved into a tube having an inclined surface to snugly wedge and latch the tramper cylinder into the upper operating position. The source of hydraulic pressure to move the wedge-shaped tongues is taken from the top of the hydraulic latch cylinder; therefore the latch may be withdrawn or released only when there is pressure in the top of the tramper cylinder, which will be forcing the tramper cylinder in the up position.
