I am more worried about time and effort to cut the grass, I am not as young as I was 20 years ago, I am 60 and my body is already broken down. I am looking at the Toro 30" walk behind mower. If I can get it past the wife then I will be able to cut the grass with less effort which is my goal. Up and down with the new mower would be like up and down and up again.
Those are bad ass. Very expensive, but well built and will last forever with residential use.
