Compare Tractor

Overview

The Lanz Bulldog HL is a German-manufactured farm tractor produced between 1921 and 1927 in Mannheim. This 2WD machine features a high-displacement 6.3L single-cylinder oil engine that delivers 12 hp at a rated 420 RPM through a simple one-speed gear transmission.

Ideal Applications

Low-Speed Agricultural Work: The engine's low rated 420 RPM and 12 hp output are designed for farm tasks requiring slow, consistent power delivery.
Basic Field Maneuvering: A 1-speed gear transmission with reverse capability provides the fundamental mechanical drive needed for 2WD farm operations.
Liquid-Cooled Operations: The hopper-cooled 6.3L engine is designed to manage heat during operation, making it suitable for sustained use in early 20th-century agricultural settings.
