I have a 22" self propelled front wheel drive toro variable speed mower purchased in 2003 (Model 20016). Worked fine when I mowed last week and today, there was no front wheel drive and the front wheels do no turn in reverse motion at all. I had a new belt installed and the there is no problem with the cable. Can you tell me what else I should look for to fix this problem?

Thank you,
Diane
