Huber B

Last Updated: July 2024

Overview

The Huber Model B is a classic row-crop tractor, well-suited for various farming tasks of its era. As a 2WD tractor, it offers the maneuverability necessary for row-crop work, with manual steering guiding its path. Powered by a 4-cylinder Buda gasoline engine with a displacement of 206 cubic inches, it maintains a steady 1300 RPM, catering to operations requiring a steady, reliable power output. The cooling system is liquid-cooled, maintaining engine temperature under workload. This tractor comes with a simple 4-speed gear transmission system, with four forward gears and one reverse, supporting fundamental agricultural needs. The engine features an American Bosch magneto and a Zenith TU4VP carburetor with a 1-inch size. The operating weight varies between 3745 pounds with steel wheels and 4650 pounds with rubber tires. Detailed tire and wheel specifications, including dimensions and air pressure values, are now included. Fuel consumption and economy statistics under different load conditions have also been added based on the test results.
