Question Toro self propel problem

I have a Toro recycler model 20448 and the self-propel isn't working correctly. I replaced the drive belt (32") thinking it was stretched out. When I lift up the rear wheels they spin like crazy, but when I set them down they don't move. It looks like the belt is slipping a bit, but I've already tightened the cable as much as it will go. When I manually pulled the drive cable tighter, the machine will self-propel. It there a way to adjust the belt tension?

Thanks for any ideas!

Some mowers have an adjustable cable. If yours is, it would have a nut on one of the ends of the cable housing, or a thumbwheel on the control handle housing to tighten it. Sometimes there is a clamp that holds the cable at the tranny and you can loosen the clamp and tighten the cable, and some cables have a spring on the end that you can turn to adjust tension. You might just need a new cable.

If you didn't replace the belt with a genuine Toro belt, I would. I have this exact model mower and have hundreds of belts at my disposal and none of them worked right...use the Toro belt. The cable, too, may need replacing although this is unlikely and I don't know your storage practices. In other words, you may have rust/corrosion issues with the cable.

I've already replaced the cable and tightened it as far as it will go. Wondering if there are any other ways to tighten the belt? Thanks for the suggestions!
