Fendt 309-312 Vario

At the end of 2005, Fendt introduced the 312 Vario, and the following year the 309, 310, and 311 models followed. This way, Vario technology was brought into a smaller size class than before. The model numbers were clearly shifted upward: the 309 Ci had a rated power of 105 hp, but the 309 Vario only 80 hp. The engines were basically the same 4.0-liter water-cooled Deutz units as in the predecessors. However, the technology had been updated: the engines now featured common rail injection, 4-valve technology, and exhaust gas recirculation. Transmission functions were controlled by a single lever; unlike the larger Vario models, the ML 75 transmission in the 300 series did not have separate field and road ranges. There was also no Vario terminal. A front PTO was available as an optional extra.

The open hydraulic flow from combined pumps and lifting capacity had only slightly increased to 78 liters and 5.3 tons. The hydraulic valves were mechanical. The brakes had been changed to oil-immersed (wet) brakes. No information on cab noise level was provided. Air conditioning was standard equipment in Finland. Front axle and cab suspension were available as options, but the 50 km/h top speed was not. The TMS system, which adjusts engine speed according to load, was an optional extra starting autumn 2007, and in Finland standard equipment from 2010 onward. Also in autumn 2007, differential lock automation and four-wheel drive automation were introduced, as well as a button clutch function for the reverse shuttle in connection with the TMS system.
