No you don't and about 30 minutes and 15 of that is getting at the PTO. Bear in mind, the Extreme clutch pulley is for 5/8" belts, so you'll have to adjust what ever belts your using accordingly. They don't make 1/2" pulley PTO's for QL's.Want to install a new Extreme clutch. Do i need a pulley pull tool? is this gonna be tough job ?
