BELT TENSIONERS
John Deere engines use two types of belt tensioners: manual and automatic. Adjust the belt using the manual
tensioner according to the manufacturer’s specifications. The automatic tensioner cannot be adjusted or repaired
and is designed to maintain proper tension over the belt’s life. Units with the automatic belt tensioner must be inspected
according to the manufacturer’s specifications.
