Take the deck off so you can get under there easier. Pay attention to the fact that as you shift the drive gears it moves the drive assy. in and out on top of the drive pulley. There SHOULD be enough slop at.. I want to say the fastest speed that you can tilt the drive assy. (the portion that sits on top of the pulley) up away from the trans pulley enough to slip the belt through.mark_the_psycho said:I have a 1980-something Snapper rear engine riding mower and I need to get the belt off. I can't see any easy way of doing it without removing engine. Please help.
