Massey 4700 Width Options

[CoolMtnTrails]

I am interested in possibly purchasing a Massey 4700 series tractor in the future. I use my current Ford 3930 2wd on some very steep hills while bush hogging. I have the Ford widened out to over 80" wide. It feels decently stable on the hills even when very steep side ways. I am concerned that a cab 4700 might not get wide enough to feel as stable or be as safe on the hills. How wide can you get theses tractors, and if I was to opt for the widest tire selection, can the tractor go even wider? Anyone use these tractors with a cab on very very steep terrain?

Sorry for rambling on, I am new here and have a lot of questions before ultimately purchasing a new machine.
