I need gash power because my old electric mower always showed much less power than most equivalent gas-burning models. I am happy with this push-mover since it's lightweight, even though I have arthritis, I can operate it w/o problems. To start the gas mower, I push the prime bulb for a while to feel the gas filling the bulb. then it can be started with easy. By just strictly following the instruction, I learned how to operate this machine. the Push mover is easier than a self-propelled one as is lightweight and easier to push.
