Introduction
Chamberlain 55DA: Standard-Tread Agricultural Tractor
The Chamberlain 55DA is a standard-tread agricultural tractor produced between 1954 and 1957 in Welshpool, Australia. With a total production run of 341 units, this machine was designed for heavy-duty field operations during the mid-1950s.
Engine and Cooling
The tractor is powered by a Chamberlain 6.6-liter (400 cubic inch) two-cylinder diesel engine. This liquid-cooled, horizontally-opposed unit features a 13:1 compression ratio and operates at a rated speed of 1200 RPM. The cooling system utilizes a thermosiphon design, which relies on natural convection to maintain operating temperatures.
Transmission and Drivetrain
The 55DA utilizes a gear-type transmission providing nine forward speeds and three reverse speeds. Power is delivered to the rear wheels via bull gear final drives, supporting a two-wheel drive configuration. Control systems consist of manual steering and mechanical brakes.
Dimensions and Hydraulics
With a wheelbase of 83 inches (210 cm) and a total operating weight of 9,000 lbs (4,082 kg), the tractor is built for stability. It is equipped with 8.25x20 front agricultural tires and 18x26 rear agricultural tires. A rear power take-off (PTO) shaft, operating at 540 RPM with a 1.375-inch diameter, allows the tractor to power various implements.
Conclusion
With its robust design, high-displacement engine, and heavy-duty drivetrain, the Chamberlain 55DA is suited for primary cultivation and general agricultural tasks requiring consistent, low-RPM torque.
