Introduction
J.I. Case LA: A Standard-Tread Agricultural Tractor
The J.I. Case LA is a standard-tread agricultural tractor produced in Racine, Wisconsin, between 1940 and 1953. Serving as a durable workhorse in the mid-20th century, the model is recognized for its robust construction and adaptability in various farming operations.
Engine and Performance
The tractor is powered by a 403.2 cubic-inch (6.6 L) liquid-cooled, 4-cylinder engine designed for LPG fuel. It operates at a rated speed of 1150 RPM and delivers 64 hp. Air intake is managed by an oil bath air cleaner, and the engine configuration features a 1-3-2-4 firing order.
Transmission and Drivetrain
Power is transferred through an unsynchronized gear transmission offering four forward speeds and one reverse speed. The system utilizes a mechanical wet disc clutch. The tractor is configured as a two-wheel-drive unit, relying on manual steering and differential mechanical disc brakes for maneuverability and control.
Dimensions and Capacity
With a wheelbase of 82 inches (208 cm) and a total length of 140 inches (355 cm), the Case LA provides a stable platform for field work. The operating weight is 3,408 kg (7,515 lbs), which can be increased to 4,926 kg (10,860 lbs) when ballasted. The machine is equipped with an open operator station.
Conclusion
The J.I. Case LA represents a significant period in mid-century agricultural engineering. With 35,493 units produced, its design was sufficiently robust to support aftermarket modifications, such as the frequent installation of Detroit Diesel 3-71 engines, confirming its utility for heavy-duty field applications.
