Jim, they are execellent machines! The TJ360 is the same thing as a JD540/548GIII The TJ460 matches the JD640/648GIII's. They are owned by Deere and for the most part are the same thing just a different color but Timber Jack gives you more options in specing out their machines than Deere does. Personally if it were my money I would buy a TJ360 cable.
