Gleaner F fit in a 11 foot door.
Gleaner F2 needed a couple inches of modification to the footing and the top header to fit in.
Gleaner F3 only fit in by letting the air out of the tires quite a bit.
Had to be real careful I never moved the combine with snow/ ice on the ground, that was enough to make it scrape....
Can't go 100% by the manual, as different tires will give you different heights, and we are right on the edge here.....
4 row wide header fit in the 17 foot width well. The 13 foot header fit in fine, but had to watch what you were doing. The 15 foot header was a couple inches too wide to fit in.
