I had to laugh when I saw this photograph on Gab:
I can just see some poor tractor driver deciding that he’s going to keep the rain and dust out, no matter what! I’m not sure about tight turns, though. That cab’s got to be delicately balanced in position. Turn too sharply, and a support might shear, and dump the occupants and the cab in the dirt. As for practicality . . . well, one can’t have it all!
