I took off the deck on my craftsman 20hp 42in lawn tractor to replace my blades. blades are replaced and good to go, hooked everything back up and how only the right blade works. Any thoughts? I thought I put it back the same way but having trouble with the troubleshooting. Thanks! - Jason Torres
I will look over the pulley tonight. I have a couple follow-up questions if you don't mind: - The belt goes with the smaller thickness side against the pulleys? - Is there a way to tighten the belt or is it suppose to be a little loose?

Ends up the spring mechanism for the left blade system was not hooked up correctly. Did a little test run of cutting the lawn with just the left blade and worked like a charm. Joys of homeownership...

the cam plate that the tensioner pulley is mounted on that rotates back around to tighten the belt as the cable or rod is engaged is likely rusted and worn, there is a bushing in this pivot that can be removed and cleaned fairly easily with a abrasive wheel or pad and lubricated upon reassembly.
Backfiring is a sign of too rich on gas and not enough air. Not enough gas will cause the mower to bog down when blades are engaged as it isn't powerful enough to run the motor AND turn the blades. Check your carb and see if you need to clean it and replace diaphgram. Sounds a lot like a carb problem.
OK. You have one of two problems, or maybe a combination of the two.lol. Either the clutch cable that runs from the lever to the deck is frozen, or most likely, the pivot point on the idler arm on the deck is rusted up and is not disengaging. Spray some penatrating oil at the base of the bracket the idler pulley is mounted on (pivot point) while working it back an forth until is loosens up. There is also a spring that is hooked to the idler arm and to a slot in the middle toward the front of the deck to pull the arm forward when the blades are disengaged. Make sure that is in place also.
It is a 46in deck, sorry!
