I have a 2011 LT2000 and have had a few issues with it. First the rod came off, but that was covered, Next mow was today and as I was mowing I heard a noise saw a little smoke and the tractor stopped moving. I doesn't look like the belt broke, but is it possible the drive belt came off? I'm sure they wont cover this. Is there any place that I could get a diagram of it?
