Wanted to give you an update on my self-propelled mechanism. Really more of a non-action update. Other than reading the on-line manual, cleaning the mower and putting away for winter, I did nothing else to troubleshoot. Well pulled it out last weekend and unfortunately the lawnmower fairy did not stop by and fix. Did pull off the above-deck cover (exposing the belts) and I see the transmission input pulley is turning, just no output to the wheels. I assume Mark may have hit on a broken gear key.
Well about 4 weeks ago I was looking on Craigslist and saw a 26622 for sale locally with another 26622 for parts. Went and looked at them, the running mower was within 80 units of my serial number, probably built in the same week! It ran okay, not as well as my engine, but the self-propelled mechanism worked fine. I purchased the running 26622 and passed on the parts mower (figured this new one or my original would end up as a parts mower). I changed oil on both mowers last Sunday and proceeded with the first cut of the year with my newest mower. Blade brake might need adjustment as the blade seemed to slow down much more than my original unit. But the self propelled worked well.
So there is my current situation, two functional 26622's that need blended into one good one. Guess I can pull the tranny off my original unit and not worry about having no mower if I screw it up.
Wife came outside last Sunday, followed by the boys, and the looks on their faces was priceless. That dazed and confused look as they peer at two identical mowers................ And the expected why don't you just buy a new one?
