MF, all depends on the grass you are cutting, if you are just mowing a lawn you set the revs you need and that is all you need to do,long grass/jungle rev it up, push it in and back the revs off when you don't need them, not rocket science, and that was how Victa tamed the Australian back yards with the toe cutters. You drive a car, come to a hill you put your foot down, go over the top and you lift your foot back off.
