They are not that valuable. I see them all the time. I wouldn't pay more than 20 bucks for one. Why? They are limited to a certain weight class -like 150 pounds. Go to the 'other site' and look up the original sales brochure. For us guys who peg the scales at 250 or so need the later Rest-O-Ride seats that were standard on the Hundred Series tractors. Those utilize the original pan seat. By the way, no need to use the Lord's name in vain.
