I have never used a snow blower so I have no input there. After having a non cabbed tractor for 12 years and now a cabbed tractor for 1.5 years I will share that experience.
At first when I went from no cab to a cab, I felt out of touch with the tractor. Over time this changed and now it’s second nature. The cab does deaden sound but I can still hear when something is amiss. My tractor does not deaden sound like a car or truck. Probably because of all the glass. I would no let that concern stop you from getting a cab if you want one.
As to working around trees, the cab is tougher than I anticipated. As a matter of fact I kept my non cabbed tractor for a while to work in the woods but ended up selling it because with care I could use the cab where I needed to.
After owning both no cab and cab, I am happy with a cab for my uses.
buck12 why is the cab tougher to use around trees? Just the height difference, or something else?
