Ursus 2812-6514






The cooperation agreement between Ursus and MF was signed in 1974. The first tractors were brought to market in 1984 and exported a couple of years later. The very old small 300-series Ursus tractors were still manufactured alongside the MF-based models until the early 1990s.
The Ursus 2812 corresponded to the MF model 235, and the 3512 corresponded to the MF 255. Both had the familiar 3-cylinder Perkins engine and an 8+2 transmission. The 3512 model with 47 horsepower was imported to Finland. The little Ursus’s cab was quite basic. Alongside these models, there were narrow, cabless models 2802, 3502, and 4502 designed for fruit cultivation in production.
In 1988, the 4-cylinder 4512 was introduced. Its four-wheel-drive version, the 4514, was also imported to Finland as a 66-horsepower base model and as a 72-horsepower DL model, which was known elsewhere as the 5514. The four-wheel-drive model had a front axle made under Landini’s license. The middle picture shows a return in Ursus design to the MF styling in Finland due to a change of importer. In 1992, the turbocharged 6514 (85 hp) was introduced, and in 1997, the models 6012 and 6014 (83 hp).
In 2004, the models in production were 2812, 3512, 4514, 5314 (71 hp), and 5714 (81 hp). Additionally, the cabless models 3502 and 4502 were available. At least the 3512 model remained in production until Ursus went bankrupt in 2011.
