In 1987 I purchased a new Wheel Horse 312-8 with a 37” side discharge mower deck. Two weeks ago the mower deck belt broke (belt was 5 years old). After I replaced it, I noticed (for the first time) the belt comes off the inside adjustable “V” idler pulley at an odd angle to the inside groove of the PTO clutch pulley. I cannot see a way to adjust the alignment of the belt. Belt life has been good – maybe 4 or 5 years between belt breakages. Could it have been manufactured like this and run this way all of these years? With the pulley support cover in place, the misalignment is impossible to see. I happened to notice it before I installed the cover. It gets a little better as I remove the slack, but not much. Any suggestions? Is this normal? Full disclosure – I had replaced the PTO clutch about 8 operating hours before this belt broke.
