This company started out with their 12-24 “Automotive” in 1919. This rig was one of the last line-drive tractors but used three lines instead of the usual pair. Two lines were used for controlling speed, operating the clutch, and steering the machine, while the third was used for gear shifting. Automotive Corp redesigned their tractor for 1920, increasing the weight from 2,800 pounds to 3,400 pounds.
