I know I've bought gears for my 49 Single Stage that's on a 318! Maybe the gear-box housing is unavailable without all the 'guts & bearings'. We've got some small tractor repair places around. I'd be happy to nose around for a used one if you have more details. Model #, and where your located, if you'd like me to look around.............Welcome to GTT! ~ScottyI have a 47" 2-stage snow blower that needs a gear box housing. I've been told by my local dealer that you can't get the parts seperatly. If anyone could help me with info on locating parts new or used i would be greatfull. Thank you.
