1990 Toro 26622, rear self-propelled with blade brake. Self propelled mechanism went out about 4-5 weeks ago, been pushing as the season is winding down. Gave it a good cleaning today as this might have been the last cut / vacuum of the year. Anyway, when raising the bale the transmission belt turns the pulley fine, can't see or hear any binding. I do see the transmission lift or rotate about the shaft so the cable seems to be doing what it is supposed to do. Does this mean the transmission is okay and I need to look at the output shaft or gears in the wheels? Guess I'm looking for a troubleshooting checklist. Thanks folks.

Take the wheels off and see if they are wore out. If not start the engine and engage the drive to see if the gears that turn the wheels are activated.
Also the drive engage cable may have came loose and out of adjustment, belt will turn but axles are not turning.

Thanks for the comments, the link was great. I'm going to study that before I start digging in. Plus there may still be one or two more cuts, actually leaf vacuuming, this year, I don't want to start pulling parts off when I still need the mower. New rear wheels were installed this spring.

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?

Looks like spring is here. Pulled out the Toro's and getting the snowblower prepared for hibernation. Washed the tandem and snapped a photo. The nearest one is my weekly mower for 20+ years now. The one behind (no bag) is the mower I picked up last year as the "organ donor". First pull on the GTS and it started! The Suzuki engine continues to amaze me, put it away for 4 months, one pull and it starts. Happy cutting everyone.
