John Deere 420C
The John Deere 420C is a compact crawler tractor built from 1956 to 1958. It's designed for agricultural work and features a unique tracked chassis for better traction in tough conditions. This small but mighty machine has a 2-cylinder gasoline engine that's liquid-cooled and naturally aspirated. The engine size is below average compared to other tractors, but it's well-suited for the 420C's compact frame. At 4,700 pounds, the 420C is a lightweight crawler that can navigate tight spaces with its 102-inch length and 60-inch width. It has a simple 5-forward, 1-reverse gear transmission and uses manual steering with mechanical disc clutches. The tractor comes with a live PTO running at 560 rpm and an optional Category 1 rear hitch for attaching implements. Farmers will appreciate the open operator station for easy access and the electric starter for quick engine starts. The 420C's mechanical band brakes and liquid cooling system with an 11-quart capacity add to its reliability in the field.
