    Re: electric pto clutch.

    I noticed that no one has mentioned the bearings. I have had to replace the bearings in the PTO on my 96 Craftsman. The bearings get rusted from the moisture and tend to seize on the shaft. I wonder if the bearings are semi-seized on the shaft and release after a period of run time. The best thing to do is remove the PTO and check it out. This has been a problem on my tractor. The first PTO was completely distroyed. The second PTO is checked from time to time and I replace the bearings as necessary. I got a little extra use out of a set by drilling into the bearing seal (very small holes) two in all and forcing in grease with a needle grease fitting on the grease gun. You pump in one hole until the grease comes out the other.

    This may or may not be the problem, but it's worth a check.

    Having a similar problem with an Exmark lazer z hp. Ran for 1--17 minutes, then the pto shuts down. Let cool---goes again until next time. Anybody have any ides?

    It sounds like an intermittant short in the electric clutch. Is that is the case, get your checkbook out. I don't know what kind of electric clutch you have, but you can take an ohm meter and check the coil resistance. I am having clutch problems right now myself. My clutch reads .2 ohms, when it should be between 2.4 - 3.4 ohms. .2 ohms is almost a short and it will kill your engine.

    I'm sure your problem is also the electric clutch. Seems to be a common problem in these "high end mowers." If you look, you can find a replacement for under $200. There is a lot of info out there. Good luck.
