Introduction
Dutra D4K-A: Technical Overview
The Dutra D4K-A is a four-wheel-drive agricultural tractor manufactured in Budapest, Hungary, between 1960 and 1965. It belongs to a series of robust machines designed for heavy-duty field operations, later succeeded by the D4K-B series.
Engine Specifications
The tractor is powered by a Csepel DT-414.5 four-cylinder diesel engine. With a displacement of 5.5 liters (336.7 cubic inches) and a bore-to-stroke ratio of 112 x 140 mm, it delivers a rated power of 65 horsepower (48.5 kW) at 1650 engine RPM. The engine features a compression ratio of 20:1 and utilizes an electric starting system.
Drivetrain and Transmission
The D4K-A utilizes a 4x4 four-wheel-drive system to enhance traction in challenging terrain. Power is managed through a gear-type transmission providing 6 forward speeds and 2 reverse speeds, allowing the operator to select the appropriate gear for specific agricultural implements and soil conditions.
PTO and Equipment
Equipped with a standard rear power take-off (PTO) unit, the tractor operates at 540 RPM. This configuration ensures compatibility with a wide range of period-correct trailed and mounted implements. The machine is fitted with 13.00-30 agricultural tires on both the front and rear axles.
Conclusion
The Dutra D4K-A is a durable, utility-focused tractor designed for mid-range power requirements. Its combination of a 4WD chassis and a reliable Csepel diesel engine makes it a representative example of mid-20th-century Hungarian agricultural engineering, suitable for general field work and traction tasks.
