It is the Curtis cab with heater. I picked it up Thursday, but went camping right after dropping it off at the house. I am a few hours away from home so I'm not able to upload images now. I will post one later tonight when I get home.
After picking it up I did notice it appears the doors will come out easily so I may not need to remove the cab. My biggest concern was cooking in there in the summer.
Lucky, I paid $5k for the hard cab and heater from curtis!! If it fits, keep it on the tractor! It's one the the best cabs. And if you use it in the winter its great with the heater. I have to put my heater on low or else I cook inside. So i am blowing snow with a tshirt on most times!
For the summer, I take off the back hard door for the backhoe, I take both hard doors off. They are just like the jeep doors. You unclick the top hydro bars and the doors slide right up and off. I also remove the windshield. If they did it right the windshield wiper will have a quick disconnect for the power. Them you can unclick the two bottom latches and unbolt the top two latches off the windshield. and they flip up and out of the way.
Just be very careful if you take off the windshield. On drop and the glass will crack or break. I ratchet strap moving blankets on the windshield, doors and back and store them in my basement all summer long. It's been so warm lately that I haven't put the kubota in winter mode yet (snow blower on, doors and cab all put back together and front loader and backhoe off, and salt spread hooked up). Maybe next week.
You don't HAVE to take the windshield off. but I like it being really open in the summer. plus I'm always afraid when digging or doing some ofther summer activity that I might crack the front windshield. Some rock or branch hitting it.
