The UTOS-45 E is powered by a four-cylinder diesel engine of 4,180 cm³ displacement, delivering 33.1 kW (45 hp) at 1,500 rpm. At an unladen weight of 2,870 kg, a wheelbase of 2,470 mm and a top speed of 23 km/h, the tractor is a solid representative of the mid-power class of its era, at a ratio of just over 86 kg of weight per kW.
Standard tractors of this type from Romanian production handled basic field work in the 1950s and 1960s: ploughing, harrowing, and driving implements through the power take-off, at a moderate rated speed typical for the period and geared toward longevity rather than specific output.
On a used UTOS-45 E from this early series, the condition of the engine and fuel system after decades of use matters most, since parts for this specific engine are only available to a limited extent today, mainly through specialised collectors and enthusiast clubs. The brakes and steering should also be thoroughly checked, along with possible corrosion on sheet-metal parts and the frame after so many years spent standing outdoors in the open.
