Introduction
Lanz D2531 Eil Bulldog
The Lanz D2531, produced between 1937 and 1954 in Mannheim, Germany, is a specialized tractor model within the Lanz Bulldog range. Known as the Eil Bulldog, this machine was purpose-built for logistics and transportation tasks rather than traditional agricultural field operations.
Engine and Performance
The tractor is powered by a liquid-cooled, single-cylinder diesel engine with a displacement of 10.3 liters (628.5 cubic inches). It produces a rated power output of 53.9 horsepower (40.2 kW) at a governed engine speed of 750 RPM. The engine features a bore and stroke configuration of 225 x 260 mm, a hallmark of the period's heavy-duty engineering.
Transmission and Drivetrain
The D2531 utilizes a gear-type transmission providing five forward speeds and one reverse gear. Power is delivered to the ground via a 2WD drivetrain, which is optimized for the tractor's intended role in towing and road transport applications.
Conclusion
The Lanz D2531 Eil Bulldog remains a significant historical example of specialized industrial machinery. Its robust design and focus on transport efficiency distinguish it from the standard agricultural tractors of the late 1930s to early 1950s, making it a notable subject for collectors of vintage German engineering.
