Introduction

John Deere 40 Utility Tractor

The John Deere 40 was a utility tractor manufactured in Dubuque, Iowa, between 1953 and 1955. Serving as the successor to the John Deere M, this model was produced in various configurations, including standard (40S), utility, high-crop, and crawler (40C) variants, with a total production run of 18,000 units.

Engine and Performance

The tractor is powered by a liquid-cooled, 2-cylinder, 4-valve all-fuel engine with a displacement of 100.5 cubic inches (1.6 liters). It operates at a rated speed of 1850 RPM and features a compression ratio of 6.5:1. The engine design incorporates an oil bath air cleaner for durability in dusty agricultural conditions.

Transmission and Drivetrain

The drivetrain utilizes a two-wheel drive configuration paired with a manual gear-type transmission. It offers four forward gears and one reverse gear, controlled by a dry disc clutch. This setup provides the necessary mechanical leverage for standard utility tasks of the era.

Operating Systems and PTO

The machine features manual steering and an open operator station. Power take-off (PTO) is provided via a transmission-driven rear shaft operating at a standard 540 RPM, allowing for the operation of various mounted and trailed implements. The tractor utilizes a 6-volt electrical system with a positive ground.

Dimensions and Adjustability

The John Deere 40 offers significant adjustability for row-crop applications. The front tread is adjustable from 39.125 to 54 inches, while the rear tread can be varied between 47.25 and 96 inches depending on the specific model variant. The tractor has an overall length of 130.625 inches and a width of 89.75 inches.

Conclusion

"The John Deere 40 remains a notable utility tractor of the mid-1950s, valued for its versatility across different agricultural and light industrial applications. Its combination of a simple 2-cylinder engine and adjustable tread widths made it a practical choice for farmers during its production years."
