Our acre of lawn is mostly bumpy, with slopes of 20 deg. (one in five)
on two sides of the house and even steeper on a third. I have never
seen a riding mower that would be safe enough from tipping (track
too narrow and wheels too small.) Just once, 30 years ago, I saw
a mini tractor with wheels at least 50 inches apart, that might do
(except that we would prefer cutters underneath, rather than a
separate tool pulled behind.

Is there on the N.American market any riding mower or mini-tractor
that can turn safely on slopes of one in five?
