I save my change all winter and then use it to pay the person who mows my lawn in the summer. I've been thinking of taking my change this Spring and purchasing a rotary mower, ( meaning, no gas or elec. Just push it), and mow my own yard. My yard is small so wouldn't take long to mow. Also, since the mower is a rotary, it would be friendly to the environment. Does anyone have any experience with this type of mower and what are your thoughts?
