Introduction

Chamberlain 55KA Standard-Tread Tractor

The Chamberlain 55KA is a classic agricultural tractor produced between 1954 and 1956 in Welshpool, Australia. Designed as a standard-tread machine, it represents a specific era of Australian agricultural engineering with a total production run of 265 units.

Engine and Cooling System

The tractor is powered by a 2-cylinder engine with a displacement of 430 cubic inches (7.0 liters). It operates at a rated speed of 1200 RPM with a compression ratio of 4:1. The engine utilizes a liquid-cooled system supported by a thermosiphon circulation method, which relies on natural convection to regulate operating temperatures.

Transmission and Drivetrain

The 55KA features a gear-type transmission providing 9 forward speeds and 3 reverse speeds, allowing for a range of operational work speeds. The tractor is configured as a two-wheel drive model and utilizes a mechanical recirculating ball steering system to assist the operator in maneuvering the machine.

Weighing 9,150 lbs (4150 kg), the tractor is built for stability during fieldwork. Its physical footprint includes a wheelbase of 83 inches (210 cm), an overall length of 135 inches (342 cm), and a width of 68 inches (172 cm). The machine is equipped with 7.50x18 front agricultural tires and 15.00x30 rear agricultural tires.

Operator Station and Implements

The operator station is an open design, common for the period, prioritizing visibility. For the connection of external equipment, the tractor includes a rear power take-off (PTO) shaft operating at 540 RPM with a 1.375-inch shaft diameter.

Conclusion

The Chamberlain 55KA is a robust, low-production, two-wheel drive tractor suited for traditional agricultural tasks. Its significant weight and specific engine architecture make it a notable subject for vintage machinery enthusiasts and collectors of Australian-built equipment.
