Farmall BN

The Farmall BN is a row crop tractor made from 1939 to 1947. It's a small, basic tractor with a 2-wheel drive system and manual steering. The BN has a simple gearbox with 4 forward gears and 1 reverse gear.

This tractor is powered by an International Harvester C113 engine. It's a gasoline engine with 4 cylinders lined up in a row. The engine is cooled by liquid and doesn't use any special methods to push air into it. The BN is light, weighing only 1,799 pounds, which is much less than most tractors. It's also compact, measuring 107.5 inches long and 65 inches wide. The tractor has a power take-off (PTO) that spins at 540 rpm, which is good for running farm tools.

The Farmall BN is an open tractor, meaning it doesn't have a cab to protect the driver. It uses old-style brakes that work by squeezing a band around a drum. The tractor has farm-type tires on both the front and back. While the engine is quite small compared to other tractors, it's designed to be simple and easy to use for basic farm tasks.
