I was mowing grass and the wheels just stopped turning. The engine cranks and runs fine. I can disengage the back lever and I can push it, but the wheels will not turn on their own.
I would check the drive belt. I know on my dad's LT1046 the spring that connects to the idler assembly for the drive belt came disconnected. We got a different spring because the old one seemed stretched. Its been 150 hrs since and no problems since.
