One of the most important tractor parts is a drive belt. If you have a belt or gear transmission in your tractor or combine, you know belt maintenance is critical to keep your farm equipment running smoothly. Over time drive belts can loosen, crack, fray or break so it’s important to continually check your belt for wear and tear.

Watch and Listen When Inspecting Your Tractor Belt

Inspect the drive and watch it run when evaluating the condition of your tractor belt. Here are a few things to look and listen for when inspecting your tractor belt during routine maintenance:

• Oil and grease: liquids will increase the chance a belt will fail prematurely
• Dirt or other foreign objects: impairs traction and increases chance of belt wear or breakage
• Added loads: shortens belt life
• Vibration: also referred to as “whipping” which is caused by not enough tension
• Belt turnover: indicates misalignment, worn sheaves or excessive vibration
• Change in rideout: a sign of uneven belt wear or worn sheaves
• Lateral vibration: also referred to as “snaking” which is caused by not enough tension
• Belt wear: wear on belt side-walls is a sign of constant slippage, excessive dust or rough sheaves
• Squeal: usually indicates insufficient belt tension or overloading
• Chirp or squeak: a sign of a dry bearing

Through routine maintenance and simply listening and watching for these signs, you can help prevent belt failures from happening while you’re out in the field.
