I have my eye on a 40" 12hp Murray riding mower, it's maybe 10 years
old or so, regular front-engine standard tractor mower. My house is
built on a hill, and I'm wondering if the slope is too great. Due to
the shape of my yard, I can't really go up and down the hill, I have
to go across the hill. I'd guess the hill is a bout 20 degrees, and
I'm nervous that the mower with me sitting on it will be too top-heavy
and flip. Or is the center of gravity pretty low in these things?

Thanks,
