Frequently Asked Questions

How do I know which fan belt fits my John Deere tractor?

Match the part number stamped on your original belt or tensioner, since drive belt lengths and rib counts vary by model and serial number. Some belts ship as sets of two, such as the AR57266 and AR43219 fan belt sets. If you are unsure, confirm fitment with our parts team.

What is the difference between a belt tensioner and an idler pulley?

A belt tensioner applies spring pressure to keep the drive belt tight, while an idler pulley routes and guides the belt without adjusting tension. We carry both, along with fan drive hubs like the RE505621 that support the belt path.

Are these tensioners mechanical or automatic?

We carry both types. Parts like the AL110621 are mechanical belt tensioners, while others such as the RE68715 and RE582500 are spring loaded automatic tensioners. Choose the one that matches your engine configuration.

Do you offer belts for 6000 and 7000 series John Deere tractors?

Yes, we carry tensioners and belts covering 6100 through 6910S and 7200R through 7310R tractors, among others. Match the part number to confirm the correct component for your machine.
