they are superior on hills if you know how to operate a stand on mower. i have experience with most of them. used standers for many years, the GS is way better hands down on comfort, hills and cut.
i never get pics, but a couple of guys on here have seen and contest to the hills i mow with them and treat with zsprays. that however requires much more skill to do
all is fair in love and grass!
Man, it smells like sheet, do you smell that!!
