Frequently Asked Questions

What John Deere forestry models do these transmission and differential parts fit?

Broken Tractor carries drivetrain parts for John Deere skidders (540, 548, 640, 648, 748, 848), feller bunchers (643, 843, 953, 959), forwarders (1010, 1210, 1510), and knuckleboom loaders (335, 435, 437). Because gear ratios can vary within a model line, verify fitment by serial number before ordering. If you are unsure, our parts team can help match the correct part number.

How do I know which transmission gear ratio is correct for my John Deere skidder?

Gear ratios can differ within the same model line, so fitment should be confirmed by serial number rather than model alone. Match the part number on your existing component when possible, or confirm with the Broken Tractor parts team so you get the correct ratio. This avoids installing a differential or transmission gear that does not match your axle setup.

Do the pivot pins come with bushings?

Yes, we carry center pivot, boom, and linkage pins with bushings for John Deere forestry machines. These support pivot articulation on skidders, feller bunchers, and forwarders. Confirm the pin and bushing part numbers against your machine's serial number to ensure a correct fit.

Can I buy used transmission and differential assemblies instead of new?

Broken Tractor offers both new aftermarket and inspected used drivetrain assemblies for John Deere forestry machines. This gives you options for different budgets on transmission gears, differential housings, and pins. Used assemblies are inspected before sale.
