I had a Kozy Kab on my Cadet 126. It worked very nicely--oftentimes, I didn't even wear gloves. I kept the back window slid open just a bit to keep the rest of the windows from fogging up. With the cab, weights, chains, and me, that tractor was almost unstoppable. My stepson called it "The Zamboni."
I predict you'll love your cab. Suggestion: electric wiper!
