DR JANE it is just a regular gas push mower....20" cut, I think.
DR RODZINSKI - my house is on a corner....my yard measured by the houses across the street is as wide as a driveway, a front yard, and second driveway, another front yard, a THIRD driveway and about 1/4 of that front yard.....and then a side yard - to say nothing of the back yard which is average size.
It is not hilly but there is an incline toward the house from the street.....
I have to say that my brother in law almost always mows the front/side with his riding mower. I only do it myself once or twice a year and the backyard has a small storage barn and clothesline poles and a rock garden and a deck and flowers and the Pet Semetary.....so I am not sure that a self propelled mower would be easy to use around all of those obstacles.
