I have a 1994 Troy built Lawn tractor with the electric clutch unit. It worked fine since it was new until now. When I first start to mow it works good until I shut it off for a minute or so. ( to move lawn chairs, hose etc.) When I turn it back on it does not work. If I use it the next day when its cold it will work fine until shut down like before. I'm stumped. This Troy built was made before they were bought out by another outfit, so I am not even sure where to ask other then you folks. Any comments or suggestion?Thanks for reading my post.
