I'm trying to remove the gearbox on an old Bush Hog RB60S. I'm able to remove all but two bolts, both on the backside of the gearbox. They run up from the mounting plate into the gearbox. Problem is there is not enough vertical clearance for a socket and not enough horizontal clearance for a wrench. And my box-end ratchet won't fit around the bolt head. The only thing that I can think to do is to cut off the tail wheel bracket to get the horizontal clearance that I need. I REALLY don't want to do that! Any other suggestion?
