John Deere L : Parts, Manuals, Diagrams, Specs

John Deere L

The John Deere L was a utility tractor produced from 1941 to 1946 in Moline, Illinois, USA. It featured a 1.3L 2-cylinder gasoline engine with a fuel tank capacity of 8 gallons. The tractor offered a drawbar power of 10.46 hp and a belt power of 12.93 hp, with tested figures slightly higher at 13.10 hp and 14.34 hp, respectively.

This compact tractor measured 91 inches long, 49 inches wide, and 57 inches tall, with a lightweight design of 1515 lb. It was equipped with a 3-speed unsynchronized gear transmission and two-wheel drive. The front tires were 5.00-15, while the rear tires were 8.00-24.

The John Deere L had a manual steering system and an open operator station with a steel pan seat. Its electrical system featured a positive ground and a 6-volt battery. The tractor was capable of pulling a single 16-inch plow.

In terms of performance, the John Deere L’s power output and operating weight were considered below average compared to similar utility tractors of its time. Its engine displacement and rated RPM were also on the lower end of the spectrum.

Despite its modest specifications, the John Deere L played a significant role in the company’s Two-Cylinder Letter Series. It was designed as a larger version of the model L, featuring a bigger engine with increased RPMs to provide more power for various agricultural tasks.

The John Deere L represented an important step in the evolution of the company’s tractor lineup, bridging the gap between smaller models and more powerful machines. Its compact size and relatively light weight made it suitable for a range of farm operations, particularly on smaller properties or for tasks requiring maneuverability.
