Introduction
La Crosse Happy Farmer M 7-12
The La Crosse M 7-12 is an early 20th-century agricultural tractor produced by Happy Farmer, a division of the La Crosse Tractor Company in Wisconsin, USA. This machine was designed for basic field operations and light traction tasks during a period of transition in agricultural mechanization.
Engine and Fuel System
The tractor is powered by a 2-cylinder, liquid-cooled engine with a displacement of 151 cubic inches (2.5 liters). It features a bore and stroke of 4.00 by 6.00 inches. The engine utilizes a Kingston carburetor and is engineered to operate using kerosene as its primary fuel source.
Transmission and Mechanical Layout
The M 7-12 employs a gear-driven transmission providing one forward gear and one reverse gear. It is configured with a two-wheel drive system and uses a manual line-steer mechanism. The operator controls the tractor from an open-station platform, typical of the design constraints and ergonomics of its time.
Performance and Capacity
The tractor provides a claimed drawbar power of 7 hp (5.2 kW) and a belt power of 12 hp (8.9 kW). These output ratings define its functional capacity, specifically allowing it to operate a single 14-inch plow for primary tillage tasks.
Conclusion
The La Crosse M 7-12 serves as a representative example of early American tractor design. With its modest power output and simple mechanical architecture, it was intended for small-scale farming operations requiring basic traction and stationary belt-driven work.
