The MAN 2F1 was a light carrier tractor with rear-axle drive and air-cooled engine, which was produced by MAN between 1957 and 1961 . In the Ackerdiesel program , the tractor held a special position because it differed from the other MAN models in size and concept. Otherwise, MAN mainly relied on large models with all-wheel drive and water-cooled engines.
The 2F1 was intended for cost-covering mechanization of small farms or for maintenance work on larger farms. From 1959 to 1960 the tractor could also be purchased as a narrow-gauge model 2F1S (S = narrow-gauge).
MAN actually launched the 2F1 too late on the market, as the demand for tractors in this performance class was already declining at the end of the 1950s. Nevertheless, the 2F1 sold very well and in the end it was one of MAN's most successful models with a total of 6091 (2F1 and 2F1S) units produced.
With the exception of the sheet metal parts (fenders and bonnet), the 2F1 was identical to the Güldner AK , Ritscher 613 and Fahr D 88 tractor models .
Technology and equipment
The 2-cylinder diesel engine of the 2F1 had a displacement of 885 cm³ and came from Güldner (Type 2 LKN). It originally developed 13 hp (9.6 kW). From 1959 MAN increased the output by increasing the engine speed to 14 hp (10.3 kW). The injection was carried out by a mechanical pump from Bosch , the injection pressure was approx. 170 bar. A special feature was the M process with which the engine works. This so-called center ball combustion process was retrofitted to the Güldner engine at MAN. The machine is forcibly cooled by a fan wheel attached to the flywheel . In contrast to most diesel engines, this engine does not have a pre-glow system in the classic sense. The compression is high enough to start the engine by cranking the engine even at temperatures below 10 ° C. For the winter there is a filament in the intake pipe between the air filter and intake bridge to preheat the combustion air, which can be activated via a switch on the dashboard.
The claw gear was a design by ZF (type A4). It had a countershaft for reducing the three forward gears and one reverse gear, so that a total of 6 + 2 speed levels were available. In addition, a manual differential lock and switchable drives for the mower and PTO were integrated.
The brake acted on the drive train and the rear wheels via the drive shafts. The front axle was designed as a swing axle . Apart from the pneumatic tires, the tractor had no suspension whatsoever.
The electrical equipment included a starter, a direct current generator, a horn and lighting with dipped beam and headlights as standard. The remote thermometer, available as an option, is used to monitor the engine temperature and was connected to the horn. It activated this when the critical temperature of the engine block was exceeded. An operating hours counter could also be ordered.
