I know it makes a difference that it was only a M with a feild lp conversion, but at an auction 2 Saturdays ago in Phx Az, a running, driving, fair tires (13.6-38), 3 wheel, PTO and belly hydraulics, no 3 pt, new paint but not the greatest quality, brought $1200. And it also came with a lp tank from a forklift.
Beside it was a 1953 super M gas, running, driving, new but weather cracking 12.4-36 tires, 3wheeler that was once a cotton picker that had been converted to a tractor only, with belly hydraulics and PTO, no 3 pt, and an equal paint job, brought $2000. And I sort of think it had a M block in it.
And the 3pt that would fit ither tractor, sold for $200.
Maybe the auction ment prices were a little softer than if they had sold privetly, but at any rate, the LP DID not bring as much as gas, and NEVER seams to.
Why? No one seams to know what to do to get them filled!!!
Sure, if you have a lp tank for your home, and the fittings to fill from it, you can do it yourself. BUT if you don't?!?!?
