Help! I took a risk and purchased an old john deere loader backhoe that is not running but the engine turns. I"m trying to identify the model number, but can't find any plate or serial numbers. I think it might be a 60's 2010, or 3010 model, maybe even a 400. I could not find the serial number plate on the frame, or on the right side of the engine housing I did locate on the right side of the engine housing where the serial number plate might have been, but no longer is. The backhoe has a model number 93; which I think is mid 60's vintage; so that gives a few clues. Once I get the model number, and approximate year trying to purchase a service manual so that I can tear it down and rebuild. Any help on identifying the model would be greatly appreciated! Thanks, Jared
