Ursus

In the 90…100 horsepower class, Ursus had offered the H-series of Turkish origin. In 2015, newly developed models were introduced, which were slightly cheaper and more lightly equipped than the H-series. The engine was a 3.4-liter Perkins, compliant with Euro IIIB standards. The powertrain in this series also came from Hattat, and the front axle from Carraro. There were 12+12 gears. The mechanical direction reverser was positioned beneath the steering wheel. The power lift was standard, as were the electrically hydraulically operated four-wheel drive, differential lock, and four-wheel drive engagement. The lifting capacity was 4,400 kg. Four hydraulic blocks were standard. Air conditioning was an optional extra. In Poland, Ursus offered a warranty of 4 years or 4,000 hours.

At the end of 2016, the 110-horsepower C-3110 equipped with a 4.4-liter Perkins engine was introduced. It had a 24+24 gearbox. The cab roof was made lower at the request of the domestic market by rearranging the ventilation components. The series also included the C-3120 HL equipped with a 3.6-liter Deutz engine, but possibly its production remained limited to prototypes.

The C-3105 introduced in 2017 corresponded in some respects to models of the smaller series, such as the C-380 K. The series also included the C-3120 equipped with a 3.6-liter Deutz engine and later the slightly more powerful C-3130. These had stage IV emission level engines and a ZF 16+16 gearbox.

Tractors

Ursus C-392 – C-3120

In the 75…90 horsepower class, Ursus used both Perkins' 4.4-liter engine and the less common 3.4-liter engine found in other brands. The transmission was Carraro's 12+12 without a creeper gear or alternatively 24+12 with a creeper gear and a hydraulic shuttle. The version with a creeper gear also featured hydraulic engagement for four-wheel drive, differential lock, and PTO. The cab was four-post and equipped with a glass roof hatch. Starting from 2017, the rims were black, following Zetor's example.

Ursus C-380 – C-395

The first 150-horsepower model, the 15014, from the new Ursus factory entered production in the autumn of 2013. It was equipped with a 6-cylinder Sisu engine and a ZF 40+40 transmission. The front axle was manufactured by Carraro. The lifting device was electrically operated and had a lifting capacity of 7200 kg. There were four hydraulic blocks as standard, with a flow rate of 90 l/min. The 250 cm wheelbase was short for its class. The cab was quite basic for a tractor in this category.

A year later, the model designation was changed to U-4150 and the engine was replaced with a 4-cylinder Deutz.

In 2016, it was decided that the correct model designation for this tractor would be C-3150. The engine was now a 6-cylinder Deutz and the appearance was updated.

In 2018, Ursus introduced its own Vigus transmission, featuring 32+32 gears and a four-speed power shift. The hydraulic output was increased to 100 liters per minute. However, in the final phase, only the ZF transmission was available, paired with a Stage IV-compliant 6-cylinder Deutz engine boosted to 163 horsepower.

Ursus 15014/U-4150/C-3150

In the renewed Ursus models, the color was still yellow, but the grille, striping, and the yellow cab roof distinguished the appearance from earlier models. Production of the new models began already in 1981, but they only reached Finland in 1983.

The updated models had a greater hydraulic output than before, and the 6-cylinder versions had higher lifting capacity thanks to two auxiliary cylinders. The engines were a new, more economical generation, with updates including nozzles, the injection pump regulator, and the crank mechanism. The rear axle and drive axles were reinforced. The turning circle of the Romanian front axle was slightly reduced. As an optional extra, Transporter transmissions were still available, which increased the road speed to 38 km/h. The model range was short-lived in Finland, as the Finn-Ursus models were introduced at the beginning of 1985. The range also included a more powerful 1604 with a 12+6 transmission, which was not imported to Finland.

Ursus 902-1214

The small 2-cylinder models C-330 (1967-93) and C-335 (1966-) were Ursus's own developments. The last part of the model number indicates the power in SAE horsepower. The technology was extremely simple, and compared to previous models, the changes were mainly limited to a renewed appearance and a stronger front axle. The 1986 C-330M had an even longer wheelbase.

The tractor in the picture is from a German brochure from the early 1970s. The most common color was orange-red. Green ones were also produced in the 1970s.

Ursus C-330 – C-335

The 2-cylinder Ursus C-325 was introduced as a prototype in 1957, and production began in 1959. The engine was a water-cooled 1.8-liter direct injection diesel with a power output of 25 hp. It had 6+2 gears, all controlled by a single lever. The tractor was equipped with, among other things, an oil pressure and temperature gauge, foot throttle, steering brakes, work light, sprung and cushioned seat, differential lock, and weight transfer system.

In 1963, updates were made and the power was increased to 28 horsepower. The C-328 was produced until 1967, when it was replaced by the C-330.

Ursus C-325 – C-328

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.
