Abstract
A PTO assembly that supplies rotational motion to at least one piece of equipment used in conjunction with a power source. The power source can be mounted on a work vehicle or in a power station. The PTO assembly is coupled to the output shaft of the power source and comprises a PTO housing with an input shaft and an output shaft rotatably mounted in the housing in a spaced apart parallel relationship. Each shaft has mounted on it three gears with corresponding gears on each shaft intermeshed. The input shaft has the three fixed drive gears. The output shaft has a high gear ratio gear and an intermediate gear ratio gear mounted to freewheel until engaged to the output shaft by a splined shift hub moved by a single shift fork. The output shaft also has a low gear ratio gear mounted on an overrunning clutch which allows the low driven gear to freewheel when either of the high driven gear or the intermediate driven gear is engaged to the output shaft.
