I was looking at a GC2410TLB today that was rotting away on a dealer's lot. This thing has been weathering probably since day one. Some of the letters are completely bleached off on some controls. The red plastic is very dull in appearance and no longer has a gloss to it. The backhoe is missing from the machine. Given that the 2400 series hasn't been out that many years, this can only be so old. How can I tell when it was built, by the serial number? I already checked tractordata.com, but they have no info for this model.
