Hi, I bought a used Craftsman LT 2000. It has had assorted problems but the latest is it just quit mowing. It's not in reverse. When I engage the mower, nothing happens. Absolutely nothing. Also, it doesn't hold a charge. It has a new battery. I have to put it on a battery charger to get it started. Sometimes it will start again and sometimes not.HELP
