I have a 5 year old Craftsman 29", 9.5 HP Briggs OHV snowblower. Immaculate condition (looks it anyway!).
Runs great, last year it began to loose it's drive. Regardless of drive speed selector position, it would stop or go to a crawl when moving into deeper snow fwd or rev. Lifting the back wheels, it would seem to regain it's pull when put back down. Kind of random.
In the fall of this year, I jacked it up, pulled off the bottom cover to inspect. There was a narrow black line on the friction disc at the low gear position. The rubber fiction wheel looked to be in good shape. The drive lever cable was a little loose, I re-adjusted that, carefully lubed the chains, hex shaft and cleaned the friction disc ensuring no oil contamination. Started it up and it pulled like an ox. Couldn't hold it back, it would drag you! Fine, great! It was fixed. I was happy.
Wrong. It stopped pulling again this last storm right away. With a little nudge it got by, but barely. It has little or no reverse.
Is it a worn friction wheel happening here, or oil contamination? Or drive belt?
I don't get it?
Anyone familar with this?
Cheers, Mark
