Excerpt from a contributor to the H.A.M.B. forum:
"That's it. That is the Comfortractor. It was designed to work in the fields Monday through Friday and then be driven to town like a car on Saturday.An all weather cab. Driving postion lowered, one door in the rear, full dashboard and gauges, heater-defroster, glovebox, cigarette lighter, a jumpseat for the Missus.
When operated as a tractor it did about 25 mph. Operated as a car it would do about 45 mph.
Cost $1900 in 1938. M-M made about 150, sold about 100 and converted the remainder to cabless, conventional style tractors when they failed to sell. The conventional model U sold for about $1000."
Picture yourself in one at 45mph on the highway...
