I can tell you the best that ive noticed on hills between a exmark, dixie chopper, and huster. I have hundreds of hours on all 3 with a 60" for each one. Dixie makes a great mower, but not for hills, they sit up to high which is great for a better field of view when mowing but not for hills. Exmark isn't bad but their controls are a bit jerky which can make all the difference when on a steep hill. Hustler I must say I liked the most for hills out of the 3, simply because it had much smoother hydros and would allow for minor turns or adjustments on hills that the exmark would simply jerk and loose traction. As many others said on here 72" decks are better (and they are) but that should be obvious because of the added weight and wider center of gravity however, they certainly do tear up turf like crazy when on steep slopes. I may add a stander to the collection next because I like the idea of a lighter more versatile machine.
