I own a lawn care company and have loved the walkers. in fact thats all i use. the cut on well manicured lawns is phenomenal. a good chunck of my accounts are the "ok" lawn as you mentioned and the cut is basically the same. i also mow some 1/2-1 acre areas of native grass that is tall and thick. the mower handles the incredably rough native grass areas, me, not so much but i deal with it. the only thing i could ask for is a better seat but im not going to pay for it.
. i would recomend nothing but walker. it is definatly a heavy duty machine
. hope this helped
