That one has the IH fast-hitch too.. Very handy, that - and quite frankly I'm surprised it's asking price is that cheap..
The field being worked in the video looks to be pretty good sized - those boys are gonna be out there a while with those rigs..
I didn't look at the picture until now. That is a pretty nice tractor.
What it seems like is there really is a wealth of 50's era semi-restored tractors in the 30hp +/- range that can be had for about $3500. You just have to find the one you want.
I think I'd be looking for someone who is bundling implements into the mix as a package deal. Spend $4500, get a bushhog, blade, box grader - kind of the tractor starter kit
