I think he was referring to the channel iron uprights.
Jenkisph, I had the dealer install cab. Cab came off of X485 I had which I put on and it's not an easy task and there is a lot involved in installing heater.
I like the cab and loader setup for moving snow and I bet that is a real handy thing to own for winter in your locale. I use a 5' rearblade with my x749 and it does a decent job with a 12" snow fall.
Wish Deere had a quick and easy way to add and remove a winter cab on these machines. If they did I would have one for winter use. Most of the year I wouldn't want any of the cab remnants in the way.
That is a nice setup you have with the cab and 45 loader.:thumbsup:
