A power take-off assembly for a work vehicle including an improved power take-off shaft for installation and removal. The power take off shaft is extended and a cut out section on the first end of the shaft is provided to engage an extended portion of a spring loaded mechanism. Once the cut out section securely fits over the extended portion, the spring loaded mechanism is prevented from axially moving in a rightward direction, thus enabling the spring to hold the gear collar in place to engage the high speed gear. The PTO stub shaft has an extended end with protruding shoulders which serve to capture the snap ring between the stub shaft and the output shaft so that when the stub is moved axially the shoulders will pull the snap ring into the groove on the output shaft which securely fastens the stub shaft. A cut-out section on the front end surface of the output shaft is also provided to allow clearance for the tool to squeeze the snap ring tabs during installation and removal.
