Postage stamps: industry and technology - Germany / Federal Republic of Germany 1975 - 80 Pfennig

A new postage stamp continuous series with representations from industry and technology replaces the postage stamp continuous series "Federal President Heinemann". The postage stamps to 80 Pfennig, 120 Pfennig and 160 Pfennig appear as further values ​​of this series with the inscription Deutsche Bundespost (at the same time and same motives the stamps come out also with the inscription Deutsche Bundespost Berlin, the first three values ​​are on 15 May 1975, further three values ​​have been issued on 14 August 1975) carry the following motifs: 80 Pf: tractor The stamp shows the Massey Ferguson tractor MF 1200. Farm tractors over 100 hp are equipped in the Federal Republic of Germany to a high percentage with all-wheel drive, in order to optimally make large part of the engine power available as traction. A new construction principle for the construction of large tractors leads to a further improvement in efficiency: four-wheel drive via four large wheels. An example of this is the tug MF 1200 with 108 hp. In its shape, this machine differs significantly from the known type of agricultural tractors. The driven front wheels have the same size as the rear wheels to transmit high tractive effort. The hydraulic articulated steering makes the machine very agile. It is therefore not steered over hammered front wheels, but by moving a joint between the front and rear axles. As a result, the large machine has the astonishingly small turning radius of only 3.7 m. The engine, a six-cylinder Perkins diesel engine, lies in front of the front axle. Extensive hydraulic control aids make it easy to steer and operate the mounted or attached agricultural implements.
