Hi All - I am new here, and new to tractors. I recently bought a used LT133, and had it taken in for maintenance. The maintenance review was good, and when the shop brought back the tractor, the blades wouldn't engage. I noticed that the belt was off. Well I put it back on (as far as I can tell) and the blades then engage. When I was mowing, and after, i noticed a strong odor. Kinda smelled electrical, but smelled more like burning leaves, or something similar. I noticed small amounts of smoke coming from under the seat. Does anyone have any idea what that might be? Are there electrical wires that run under the seat? I need help The smoke and burn smell were not done prior to it going in for maintenance.
