my dad and i picked up a ('62 i think) 4010 diesel for a good price to fix up and maybe sell, its more or less all original, but well used. my dad thinks this one is rare because it has from the factory, no rockshaft unit(no 3 point hich). it has dual remotes, oil bath filter, originally wide front end, (but currently narrow, with original wide front end assembly ready to be put back on over the winter). my thought was that as a base model w/out 3 point hitch, its not worth as much, he thinks its rare-ish and a collector piece when restored and might be of interest the way it is. so, what is a 4010 like this worth? and would it be worth more if it had a functional rockshaft unit? thanks for the help!
