Frequently Asked Questions

Which John Deere skidders does the AT79955 heater core fit?

The AT79955 heater core fits John Deere skidder models including the 540E, 540G, 540G-II, 548E, 548G, 548G-II, 640E, 648E, 648G, 648G-II, 740E, 748E, 748G, and 748G-II. It also covers several other John Deere machine lines. Match the part number to your machine or confirm fitment with our parts team before ordering.

What is the difference between a heater core and an evaporator core for a John Deere forestry cab?

A heater core carries hot coolant to warm the cab, while an evaporator core is part of the A/C circuit that cools and dehumidifies incoming air. Broken Tractor carries both as copper tube-and-fin cores built to OE fitment. Choose the core that matches the HVAC circuit you are servicing on your machine.

Does the RE327083 evaporator core fit John Deere feller bunchers?

Yes, the RE327083 copper tube and fin evaporator core covers John Deere feller buncher models in the 803M through 959M range, along with 803MH through 959MH, 953ML, and 959ML machines. It also fits the 670G through 872GP tracked harvester series. Confirm the part number against your machine to be sure of the correct application.

Which heater core fits a John Deere 872G forwarder-class machine?

The AT362078 heater core fits John Deere HVAC systems including the 620G, 622G, 670G, 672G, 770G, 772G, 870G, and 872G. It also covers 803M through 959M feller bunchers and several other models. Match the AT362078 part number to your cab HVAC system before ordering.

Should I replace or repair a leaking John Deere A/C condenser?

A leaking or corroded A/C condenser is usually replaced rather than repaired, since a new unit restores proper heat transfer and system pressure. Broken Tractor offers new aftermarket condensers such as the AT184522 vapor condenser and the AT83363 condenser built to OE fitment. Match the part number to your model, or call (800) 909-7060 for help confirming the right condenser.
