Not sure about the meditative part but I am more comfortable with the quiet and dependability of a manual mower. No gas, no oil, no "why is the thing running so ratty THIS time?", no overpriced batteries to replace, no cord to cut by mistake. The price was right as it was free at the dump and it works any time I want it to.
Family down the way has a Sears model and it cut badly. No grease in the drive wheels-what there was had dried out. The main problem was the cutter bar-it was set for another universe and if the cutter bar is off a push mower will not cut well at all.
Enjoy the meditation.
