I cannot get the tire/ wheel off the mower. I undid the C-clip and removed the washer. The wheel will come off the axle, but instead of the wheel coming off, it seems there are quite a few components that are connected to the wheel. I have the exploded parts diagram, bit it really is not helpful in understanding what has to be removed to free the wheel.
Here is the parts diagram. The wheel assembly is on page 11. It seems the wheel / tire should come off easily!
