Introduction
John Deere D Tractor
The John Deere D is a standard-tread tractor manufactured in Waterloo, Iowa, between 1923 and 1953. It holds the record for the longest production run of any John Deere tractor model, serving as a primary workhorse throughout several decades of agricultural development.
Engine Specifications
The tractor is powered by a 2-cylinder, liquid-cooled all-fuel engine with a displacement of 501 cubic inches (8.2 L). It operates at a rated speed of 900 RPM. The engine features a 6.75x7.00 inch bore and stroke, with a compression ratio of 3.91:1. Cooling capacity ranges from 49.2 liters in early models to 53.0 liters in later units, while the oil capacity is 12.3 liters.
Transmission and Drivetrain
The drivetrain utilizes a two-wheel drive system managed by a manual steering setup. The transmission consists of unsynchronized gears. Initially, the tractor was offered with a 2-forward and 1-reverse gear configuration. A 3-speed transmission, also with a single reverse gear, was introduced in 1935 to provide greater operational flexibility.
Dimensions and Operator Environment
The machine features an open operator station equipped with a steel pan seat. Over its long production history, dimensions evolved; the length increased from 109 inches (276 cm) to 130 inches (330 cm) after 1930. The tractor's weight also varied, ranging from 4,090 lbs (1,855 kg) for early versions to 5,880 lbs (2,667 kg) for later, heavier iterations. The width remains constant at 56 inches (142 cm).
Power Take-Off
An optional rear Power Take-Off (PTO) was available for the John Deere D, utilizing a 525-type specification to drive auxiliary equipment.
Conclusion
With over 160,000 units produced, the John Deere D is a historically significant machine. Its robust, simple mechanical design and long-term reliability made it a standard solution for heavy-duty agricultural traction and field work throughout the mid-20th century.
