The Ursus 300 range – Polish twin-cylinder tractors C-325 and C-328 from Warsaw: 18.4 to 20.6 kW (25 to 28 hp), 1,654 kg unladen weight
In Ursus's type logic the 300 range follows the early C models and here brings together the closely related C-325 and C-328 – two twin-cylinder diesels from the Polish maker Ursus near Warsaw, which differ mainly in output and track width but otherwise share largely the same basic design. Both types targeted smaller and medium farms that needed a simple, robust general-purpose tractor.

The register lists 2 versions with 18.4 to 20.6 kW (25 to 28 hp) from twin-cylinder engines of 1,810 to 1,961 cm³, torque of 93 to 100 Nm, an unladen weight of 1,654 kg, a length of 3,030 mm, widths of 1,250 to 1,680 mm, a height of 1,500 mm and rated speeds of 2,000 to 2,200 rpm.
The 300s were among the common smaller tractors of Polish farming and served as general-purpose tractors for smaller and medium holdings, where manoeuvrability and low fuel consumption mattered more than high drawbar pull; within the Ursus range they thus sat a step below the larger, more powerful lines.
On used examples, the condition of the injection pump, the tightness of the cylinder head and cooling system, the state of clutch and gearbox, and rust on mudguards and bonnet all count; spare parts run through Polish farm-machinery dealers and the used market, and aftermarket reproductions for wear parts, since factory-original stock is largely exhausted after so many decades.
