How to Identify and Fix Common Gardening Problems ?

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.
Slipping can be the result of a loss of belt tension (or a weak automatic tensioner) or pulley misalignment. When the belt slips off the track, the friction between the belt and accessory drive pulleys causes the belt to overheat. If you hear a high pitched squealing noise, it`s probably time for a switch.
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.
A perfectly tight mower belt can rotate without slipping off but not cause the engine to over-exert and overheat. If the belt does not slip off while working and is not producing unfavorable sounds that indicate wearing off of the belt, then that is the perfect tightness for it.
Improper belt tension is the most common and obvious cause of slip, which generates unwanted heat. The friction that occurs when a V-belt slips in a pulley causes belt sidewalls to become glazed, and decreases gripping ability.
Unexpected noise: A squealing noise often indicates slippage between the belts and the pulleys. A chirping sound could stem from misalignment of a pulley or drive belt, as well as a host of other issues. Tensile failure: A common indicator of misalignment, tensile failure may be due to uneven cord loading.
Check on how the belt gives way to your pressure; it should not be loose enough to give way more than a few inches. For mower belts that give way more than two inches, you need to tighten them according to the model`s manual.

Belt for self popelled mower keeps breaking? Cannot keep a new belt on pulley
ANSWER : 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.

Deck belt keeps tearing up then falling off
ANSWER : If it’s an idler pulley, where the belt changes direction from the engine – yes it should turn freely. If it’s a double pulley where the drive pulley from the engine connects with the deck/blade pulley, then it it’s not going to turn totally free because of the blade pulleys connected to it. But in all cases, none of the pulleys should be seized. Try using WD40 or PB Blaster on the pulley bearing surface to loosen it up – or a new pulley…
