I suppose there are a variety of reasons for not wanting a cab. My 1170 came without air conditioning so the enclosed cab was hot in the summer.
For summer, it is somewhat easy to remove the door so I do that. I removed the double links from the back window and made light angle iron links long enough to hold the rear window open 90 degrees. I open the right side window and no more hot cab.
Just finished 3 days of planting wheat and there was a nasty windchill. I put the door back on and closed the windows. Cozy cab for fall and winter.
