Re: safe slope angle for hills
One other thing to consider, especially for extended use on side slopes, is that some engines can suffer from oil starvation when held at too severe an angle. It's been a while since I had to spec out an OEM diesel engine, but I recall that the "same" base engine could have radically different slope capability, I believe primarily based on the oil pan configuration. It may be hard to get this info for CUT engines ( I was dealing with 4 and 6 cylinder diesels 80-200 Hp) but keep this in mind when looking at your equipment.
You may want to look into adding duals to your mowing machine for side slope use, as this can have a great effect on the sideways stability of the machine. There are also some tractors, primarily configured as golf-course or mowing tractors, with lower clearance and wider machines. I know I've seen Fords like this, and THINK I've seen a Kubota like this, but I could be wrong.
