Merk Pullax
3 models in this series
Merk Pullax – the P20, P 30 and P 40 models with two- to four-cylinder diesel engines, 15.7 to 30 kW and a type designation based on approximate horsepower
The Pullax range comprises the Pullax P20, Pullax P 30 and Pullax P 40 models. The type designation follows the practice common among small tractors of the period of carrying the approximate engine output directly in the model name: the P20 is close to 21 hp, the P 40 close to 42 hp.

The register lists 3 versions with 15.7 to 30 kW (21.4 to 42 hp) from two- to four-cylinders of 1,145 to 2,290 cc displacement at rated speeds between 2,500 and 2,700 rpm. Operating weight ranges from 1,430 to 4,200 kg, length from 4,400 to 5,900 mm, width from 1,690 to 1,800 mm and height from 1,420 to 1,600 mm. All three models run on diesel.
The wide span of weight and length across the three models shows that the Pullax range covered a broad output spectrum, from a light small tractor to a markedly larger, heavier version, rather than being confined to a single vehicle class. The consistent diesel fitment across all three models sets the range apart from many contemporary petrol or dual-fuel tractors from smaller makers.
On a used purchase of these historic diesel tractors, points to check include the condition of the injection pump and nozzles, the tightness of the radiator and fuel lines, wear on the clutch and gearbox, and corrosion on the chassis and sheet-metal parts. Spare parts for this little-known brand are found mainly through collector markets for farm machinery.
