Model #917272961 Craftsman lawn, tractor

Question and Answers


I have a craftsman 48inch 20hp garden tractor, that keeps burring up ground drive belts


The most common cause for belts smoking on riding mowers and tractors is the bearing in an idler pulley seizing. I suspect this is what is happening to you.

Sometimes the idler bracket gets bent if it hits something. Using the clutch to make the tractor move forward or backward instead of the motion drive lever will also bend the idler bracket sometimes. You should only use the clutch to engage the transaxle after starting the engine. The motion drive lever should be used after that to stop and start the tractor motion.

You would probably be better off to replace the idler pulleys and the bracket.
