Tractor Info

1919-1930

The Allis-Chalmers 20-35 was the lowest priced 4-plow tractor. The operators seat was moved froward and raised to give the driver a clear view. Its motor was fully sealed from dirt and it exceeded heavy work expectations. It also offered a short turning radius which made it usuable in many situations.
