Answer
The most common problems with your mower's drive system is the wheels wearing out and the drive pawl sticking.  The only fix for the wheels is to replace them.  As for the drive pawl, a small pin, you can remove the drive pinion gear and make sure the pin moves freely.  If it is dirty or rusted you should be able to remove the pin and clean with sandpaper or steal wool.  Don't forget to clean the axle hole where the drive pawl goes through as well.

Let me know if this helps.
