Row to chest and lawnmower to waist or lawnmower to chest and row to waist?
Lawnmower to waist...probably. At least, that's how I start my lawnmower.
My lawnmower starts with a switch.
You have to get the push-mowers and use it for gpp. Do it for time or distance.
I have no idea how my lawn service starts their mowers.
