Both. Rider for the wide open areas, push mower for around some trees and bushes, and some weed whacking along the ditch between our property and the road. About 1 and a half acres of the 2 and a half acre lot is lawn. The remaining acre is wooded and adjoins many more acres of woods and wetlands.
Ok. I have a four wheel drive push mower - hilly lawn but too small for a rider.
I have neighbors where the most exercise they get is emptying the grass clippings from their rider.
