If you have a John Deere riding lawn mower, you know that keeping the deck belt in good repair is essential to the function of the mower. But if you find that your deck belt keeps breaking, there are a few possible reasons why.
One reason why your John Deere deck belt may keep breaking is because the idler pulley is not working properly. The idler pulley is responsible for tensioning the deck belt, so if it's not functioning correctly, the belt will be loose and can easily break. Another possibility is that the blades on your mower are dull or damaged. Sharp blades are necessary to provide a clean cut and prevent damage to the grass; however, dull or damaged blades can cause undue stress on the deck belt, causing it to break.
If you're having trouble with your John Deere deck belt keep breaking, it's important to troubleshoot the problem so you can fix it and get back to mowing your lawn!
