can whlvr 994 #1 Posted September 9, 2012 so today i was working the 312-h real hard ripping the driveway up with my grader blade with teeth,then i lost all hydro and i s--t my pants thinking the tranny just died,then all of a sudden the belt blew off,so i looked on parts tree and toro and the 312-h uses the same belt as all of my 8 speeds ??is this really true,or am i reading the parts breakdowns wrong,i have several uaed 7473 so im gonna try it,but i thought i would ask anyone that has this model if its true Share this post Link to post Share on other sites
TT-(Moderator) 1,162 #2 Posted September 9, 2012 This is what I see: Hydro: 108501 @ 81.5" / 0.625" ~ HB/5L Gear drive: 7473 @ 81.95" / 0.656" ~ HB/5L You might get away with a 7473 temporarily, but I highly doubt it. Share this post Link to post Share on other sites
Forest Road 594 #3 Posted September 11, 2012 Look at the 314h in my avatar. That's a home made 1/2" 3 braid rope custom belt that limped the tractor and blower into the garage. Where there's a will there's a way! I ended up at a NAPA store a few days later. $20 or so and I was back to normal. Share this post Link to post Share on other sites
