I am not positive, but I'd bet a grand (your money) that I have seen complete enclosures for sale at places like SkidSteerSolutions.com, etc. I am sure that if you do a Google search, you will find them. I'm just playing devil's advocate, but I would not own an enclosed cab, at least not the front door part. Too often I have to get out of the machine w/ the arms up a tad, and a door would not open then. It is just constant; you're lifting something and have to get out to adjust a chain, move a pallet, etc. I prefer to get dressed for the cold and stay that way. Maybe I'm just cheap and rationalizing, but if you are dressed to be in a heated cab, how are you going to go out and work 10 minutes at zero degrees? I don't spend tons of time on the loader when it is cold, but I just plowed my driveway at -15, and it is a cake walk, if you are dressed for it. Even in the fall when it's 40 degrees, I'd prefer to hop in and out. Just my thoughts. Good luck.
