John Deere LA

Last Updated: July 2024

Overview

The John Deere LA is a vintage utility tractor that was part of Deere's early foray into tractor manufacturing. Known for its simple yet effective design, it features a 4x2 2WD chassis and is powered by a 2-cylinder, 77 cubic-inch, liquid-cooled gasoline engine with a rated RPM of 1850. It utilizes a manual steering system and a 3-speed unsynchronized gear transmission that includes 3 forward gears and 1 reverse. With a total weight of 2,200 pounds, key measurements of the John Deere LA include a length of 93 inches, a width of 47 inches, and a height of 60 inches. It rides on 15-inch front and 24-inch rear agricultural tires, supporting traditional farming applications of the time. The absence of certain modern amenities speaks to the period of its manufacture, and the LA's specifications reveal its role as a reliable workhorse of its era.
