Lock the shaft? Why? The electric PTO clutch is bolted on to the shaft of the motor. First remove the bolt in the end of the shaft .It has a key way so it WILL not turn on the shaft. It is not screwed like a chain saw clutch. You remove the bolt and with any luck you will be able to pull it off the shaft. The problem comes when it gets rusted on the motor shaft. Clutches that I have known for a fact were no good and were trash I have had to destroy to remove. If the PTO clutch is still good it can be fun to get off some times. DO NOT use heat on a clutch you plan on reusing because it will melt the coil and destroy it. Always use anti-seize compound when putting on a PTO clutch. You can not even use a puller on most of the clutches with out destroying them. If you have a stuck PTO clutch you wish to remove and reuse go get a few cans of WD-40 and pray. Good luck

fixer,
i'm trying to get the clutch off of a simplicity mower. when i turn the bolt that holds the clutch (PTO) on the shaft - the shaft turns inside the clutch - the engine turns. i need to stop the engine shaft from turning so i can get the bolt loose. no what i mean??

Sorry about that. I had a man in the shop last summer that though his electric PTO clutch screwed off like his chainsaw did. You need an impact gun. That will knock it loose before the engine has a chance to turn. You can try taking the blower housing off and locking now the flywheel. Now there is an old shade tree trick that can be used to lock the engine down. First remove the spark plug and then turn the engine over until the piston is at the bottom. Then take about 5 feet of small rope like the type used for pull cords. Tie a knot in the every end of it, there is a reason for the knot. Then poke the cord in to the spark plug hole until you can not get any more in but remember to leave some to pull it back out by. then turn the bolt you are trying to remove. When the piston comes up to top it jams against the cord and you can remove the bolt. When done remove the cord and look for the knot at the end. When you see the knot you know that all of the cord is out. On 4 cycles the knot is not that necessary but when the cord trick is used on 2 cycles it can get cut in to on the ports and the knot tells you if it is all there or not. The cord trick is an old trick you will not find in any book but it does work and it gives you some to to use when all esle fails. Good luck.
