Tractor Info


Variously rated as an 18-30, and later as an 18-35, the
Square Turn tractor remained basically unchanged during
its entire production. The Square Turn used a unique
system of fibre-faced driving cones which enabled one
drivewheel to travel forward and one to travel backward
in making a sharp turn. In 1920, the tractor had an 18-35
horsepower rating and used a 5 x 6 1/2 inch four-cylinder
Climax engine. The builders claimed it to have a 3,200
pound drawbar pull. Total weight was 7,400 pounds, and
the 1920 price was $1,875. After a meteoric rise, the Square
Turn interests were sold at a sheriff’s sale in 1925.
