Help, I need to come up with a reasonable price for this machine. It has been stored in a warehouse unused for years. The undercarrage shows little use. It pushes great forward in all gears. It is slow with little power in reverse gears 2 and 3. first works great. The machine has no damage and runs and operates great. The front blade is very tight with no damage. The machine is 20 years old but is in great shape. What is it worth? Was this a good year for these machines? The owner doesnt want to part with it cheap. Will I be better off with a newer machine with more hours?
