Hi, we've slowly rebuilt our lawn tractor over the last 11 years. Just last month we put a new deck assembly on it. This afternoon, it quit moving while the motor was running. The deck had quite a vibration and the belt squeals. I looked underneath and found all three belts attached and in good shape. They were replaced two years ago.

My husband isn't able to help with this problem. He just had major back surgery less than two months ago, having 10 vertebrae fused. He can't get on the ground, plus he's still under the influence of pain meds.

Could this be a problem with the installation of the deck (our neighbor helped install it)? A belt? Or do I need to get it to a repair shop? Thanks for any help you can give! It's been a really rough 2008 so far!
