Introduction
Dutra D4K-B: Technical Overview
Produced in Budapest, Hungary, between 1964 and 1972, the Dutra D4K-B is a four-wheel-drive agricultural tractor designed for heavy-duty field operations. This model succeeds the D4K-A series and represents a significant period in European tractor manufacturing, specifically integrating the Perkins 6.354 engine to meet the requirements of Western export markets.
Engine and Performance
The D4K-B is powered by a Perkins 6.354 diesel engine, a 6-cylinder unit with a displacement of 354 cubic inches (5.8 liters). It produces 100 horsepower (74.6 kW) at a rated speed of 1850 RPM. Featuring a compression ratio of 21:1, this power plant is configured for consistent torque delivery in demanding agricultural environments.
Transmission and Drivetrain
The tractor utilizes a gear-type transmission providing 6 forward speeds and 2 reverse speeds. Power is delivered to all four wheels via a 4x4 drivetrain, which enhances traction and stability on uneven or soft ground. This configuration allows operators to match ground speed to various implement requirements.
Hydraulics and Implements
Equipped with a rear Power Take-Off (PTO) system capable of operating at both 540 and 1000 RPM, the D4K-B accommodates a wide range of powered implements. It features a Type II rear hitch, providing the necessary lifting capacity for standard agricultural equipment of its era.
Dimensions and Chassis
The machine has a wheelbase of 76.8 inches (195 cm) and a total operating weight of 11,240 lbs (5,098 kg). It stands 99.6 inches (252 cm) high with the standard factory cab. The tractor is fitted with 15.00-30 tires on both the front and rear axles, supporting its overall weight distribution and ground contact.
Conclusion
The Dutra D4K-B is a robust, mid-range 4WD tractor engineered for durability. Its combination of a high-displacement Perkins engine, versatile PTO speeds, and substantial weight makes it suitable for heavy cultivation and traction tasks, reflecting the industrial standards of its production era.
