How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
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.
If a belt is not tensioned properly, it will ride too loose or too tight on the pulley. A belt that`s too loose on a pulley will cause slippage, which leads to heat build up from friction. This heat will damage your rubber belts and cause the belts to crack and break.
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.
The Craftsman primary drive belt is compatible with many 42″ deck tractors. Lightweight, this replacement drive belt is designed to fit on riding mowers and serves as the engine to deck primary drive belt. Make your mower run like new with a quick belt replacement.
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.
There is no specific time length that mower belts need to be replaced. Some belts may last longer than others due to different operating conditions. One thing is for certain though, the more the mower is used, the sooner you will need to consider replacing the mower belt.
Usually there are two belts. One goes around two pulleys, a front pulley under the motor and one on the mower deck.
Place your hand on the belt and push the belt down and toward the pulleys. 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.
