MTD Riding mower belt gets hot
I purchased a MTD riding mower with a 20HP Tecumseh engine and a 46 inch cutting deck. It runs great as far as the engine goes. However, I was using it about a week ago, on some tall grass, and some smoke started coming out from under it. Ever since then when I use it the belt gets hot and smoke comes out from underneath it. Also, if I throttle up the belt will pop off. It is easy to put back on, but I'm not sure what the underlying problem is. Any Ideas?
Also, there is a spring that i hanging off the back of the cutting deck. It is attached to a lever that presses up against a belt. I assume the spring puts pressure on it. I don't know where this is supposed to be attached to.There is a bolt hanging off the back of the transmission where another spring is attached, I placed it there, and it was tight as long as the deck was disengaged, but would pop back off when I engage the deck.
