The International Harvester 645 is a diesel-powered tractor equipped with a 4-cylinder International Harvester D-206 engine. It showcases a liquid-cooling system to maintain optimum operating temperatures and has a 206.4 cubic inch displacement. The engine's bore and stroke measure 3.875 inches and 4.38 inches, respectively, and it operates at a rated RPM of 2180, delivering a power output of 66 horsepower. The tractor's robust build is reflected in its operating weight of 8160 pounds. Dimensionally, it extends to 138.6 inches in length, 75.6 inches in width, and 88.6 inches in height. The tractor hooks up to implements via a Category II hitch system but it is not clear what type of steering, transmission, or tire configurations it uses, as those details were not provided. This model would be appreciated for its substantial power and solid construction, which suggest it might be well-suited for a variety of heavy-duty applications on farms and fields.
