Selection
Choosing this part
The tall rear wheel that gives the 20339 its "High Wheel" name. Toro describes it as designed for walk-behind push and front-wheel-drive mowers — which is a statement about intent, not an exclusion, so we do not record it as incompatible with anything. If your machine drives its rear wheels, check what Toro lists for your own model and serial range rather than reading across from this one.
