Your riding mower belt keeps coming off because of several possible causes such as a damaged, dirty, or incorrectly installed belt. This problem can also be due to an oil leak, damaged mower pulleys, damaged bearings, or a misaligned or stretched out belt.
Belt slipping off tensioner pulley is a common issue that can occur with any type of belt-driven system. The most likely cause is that the tensioner pulley itself is worn out or damaged. In some cases, the problem may also be caused by a misaligned pulley or by a loose belt.
A common cause of belt breakage is excessive grass clippings on the deck. Grass clippings can work their way under pulleys and deck covers, causing series problems. Make sure to clean off your deck after every mower use and follow manufacturer recommendations.
It`s quite simple, really: your car cannot run at all without a timing belt. If the belt breaks while you are on the road, the car will break down immediately – and your engine can experience severe damage.
A: Your mower has two belts. Both play a role in making the blades turn. The “Deck Belt” goes around the pulleys right above the blades on the deck and then to a double pulley. The “Drive Belt” on your mower goes from the transmission, around an Idler pulley then over to the double pulley I mentioned before.
Wander Due to Faults with Splices or the Belt
Improper belt splicing is a significant cause of mistracking. If the belt is not spliced squarely, the belt will wander back and forth on the conveyor structure. This can usually be seen at the tail pulley.

Belt for self popelled mower keeps breaking? Cannot keep a new belt on pulley
Check that the pulley isn’t seizing up and causing the belt to snap, also be sure you loosen up the self propelled mechanismn by spraying down with WD 40, too much belt tension can cause this, but it rather seems like the belt pulley seizes and the engines drive pulley keeps turning causing the belt to overheat and break or stretch and come flying off.

ROUTING OF BELT – Mtd Drive Belt 42"
Diagram is on the mowing deckBest regardsCk
I cant replace the deck belt on my husqvarna ct151 lawn mower. the old one snapped and i have no idea what way the new one goes on around the pulley wheels.
The manual shows how the belts are put on, if you do not have one they may be purchased through dealers or small engine repair shops or online. On mine there is also a little diagram on the top of the mower deck. Another way to check is find an identical one that is functional and look at its belt. There are only so many ways it could fit and these are all made by just one or two manufacturers so there is not much variance.
