Ursus C-45 – C-451

The Ursus C-45 was a copy of the 1940s Lanz Bulldog. The single-cylinder hot-bulb engine could run on almost any oil product as fuel. The starting operation lasted about 20 minutes. The engine parts are interchangeable with those of the Lanz. A special feature of the tractor was its spring-suspended front axle. The maximum driving speed was initially 6.2 km/h. In the C-451 introduced in 1954, which was equipped with rubber tires, the speed was already 16.7 km/h. The newer model also came standard with a mechanical lift, steering brakes, an electrical system, and gasoline starting.
The importer of Ursus in Finland was Oy Atkinson Ab, but sales remained limited to individual units.
