dalt1 - let me know if you have an oil plug leak. I have the same mower as you (2010) model and the oil plug leaked. It appears to be the wrong plug because the o-ring does not touch the seat. I had to purchase a gasket that it is not designed to use to get it to stop leaking. Toro dealer wouldn't do anything even though I showed them two Kaw FX engines on their showroom floor that were also seeping oil. Hopefully Kaw has fixed this obvious defect.
Other than that I like the mower. Agree the brochure was wrong on the tires.
