I was looking for a decent tractor with a rear tiller attachment, to get one I ended up buying a lot of tractors at an auction.
One of the tractors in the lot is a 312 Variable speed which has issues with the variable belt drive or BGB. During the auction a few guys had looked over the machine, and all seemed to think the BGB was shot, but what gets me is that the tractor runs and cuts fine? It does slip when the variable lever is moved all the way down though. If I grab the BGB pulley, the outer sheave turns about half way before the shaft moves, the inner is fixed tight to the BGB shaft.
I really haven't figured out how this thing works, the belt is super loose all the time, I can turn the belt by hand without moving either pulley, yet it moves fine and mows grass well.
Is the drive pulley supposed to be two piece?
Along with this machine, I got a rough but functionally perfect 3410S with a rear tiller and deck, plus two older AC's, a B110, and a B1. The B1 looks decent but is missing its muffler and has no spark. The motor cranks and has strong compression. The B110 is complete, runs a bit rough but cuts grass and has a deck.
I'll probably sell off the two older AC's and keep the 312 and the 3410S.
I'd really like to set the 312 up as a snow plow only machine, I don't need the variable drive and would like to just toss it and convert it to a straight three speed if possible. I'm open to suggestions on this matter.
I like the B1 but I'm too big for it, and I really don't have room to store a tractor I can't use.
