Unhappy zt7000 craftsman blades slow down in heavy Grass

Yes under a load the blades slow down. This is what I have done so far.sharpened the blades, replaced all belts, checked the spindells, have taken off the pto, It engages and the blades spin fine with no load on the blades, Also have adjusted the gonernor to give it more power. Is it possible that the pto is slipping under a load

Thanks in advance
Bob

Does it use an electric clutch? Do you hear any squealing or grinding noises when they slow down? Does the motor seem to slow down proportionate to the amount the blades slow down?

yes it is an electric clutch. When I engage it the motor revs up and the blades spin fine . When I cut the grass the blades and motor seem to slow up

You've probably checked already for the obvious, but is the underside of the deck clean and not clogged?

If the motor slows down right along with the blades I doubt there is any slippage in the PTO drive. Sounding more like an engine lose if power issue.

Any idea how many hours it might have on it? Maybe it is just getting worn and running low on compression?
