Hi, my name is Chris Perry and I have removed the PTO from my EXMARK lazer z( model # LHP19KA465). The removal of this was very easy , but the problem Im experiencing is putting on the new one. Im not aware of how to prevent the motor from turning as i bolt in the new PTO. Im aware that on other models you can grip the shaft and prevent it from moving that way, but mine isnt built like that. The PTO sits directly under the engine, so theres no shaft to hold. The motor on this machine is a 19hp kawasaki. Any ways to prevent this from spinning while bolting on PTO ? THANKS!!!!
