Self Propelled Mower wont propel

The problem I had was that the wheel mounting plate was not parallel with the mower body. The plate was "toed in" on both sides. This caused the wheel gear teeth to only catch the edge of the metal gear. The solution is to the make the plates parallel. I accomplished this in about 5 seconds using a correct thickness nut. I simply pried (flexed) out the wheel mounting plate from the mower body using a large screwdriver. Where the wheel mounting bolt comes through the plate you should see a couple of treads. I used an oversized nut to cover the threads and released the tension on the screwdriver. The nut is now pinned between the plate and the mower body. Make sure the wheel looks straight. If not change to a thicker or thinner nut. Because the nut covers the threads when you go to move the height adjuster the nut will move with the plate. It may be a little stiffer to move but it will move. I did this to my lawn boy mower a couple of months ago and it has worked perfectly since. I think Toro and Lawn Boy have the same mounting system. Good luck . Here is the link to my solution. Read the comment with each photo. Wheel Grinding Fix and Cable Repair For Self Propelled Mower
