Fendt VarioDrive refers to a completely new generation of continuously variable transmission technology. The foundation is the single-stage drive train with independent control of the front and rear axles. The transmission continuously measures the slip on all four wheels and sensitively regulates the power output. For the first time, Fendt VarioDrive combines the four key functions of maximum tractive force, simultaneous ground protection with minimum wear and ground-breaking manoeuvrability. Dynamic control prevents wheel slip, with maximum traction regardless of the surface. The drive train eliminates the need for manual switching when changing between field and road operations. In this way, VarioDrive automatically combines maximum tractive force, high ground protection on any surface without distortion, loss of performance or tyre wear.
The so-called pull-in-turn effect pulls the machine into the curve during turns due to the axle-independent control. The result: a particularly small turning circle of just 10.2 meters with 540/65 R30 tyres. The previous contradiction of maximum tractive force, maximum ground protection and lead in the drive train is resolved and sets a new standard in drive technology. This means that black wheel marks on front loader work are a thing of the past and the turf is protected on grassland.
The innovative low-speed Fendt iD concept is available for the first time in this compact performance class. All components, such as the engine, transmission, hydraulics and cooling system, were designed according to the so-called "high torque – low engine speed" principle. In this way, the Fendt 600 Vario achieves high torque even at low engine speeds and saves fuel. The rated engine speed is only 1,900 rpm. In the main working range, the speed is a quiet 1,350 to 1,800 rpm. The top model Fendt 620 Vario can reach a top speed of up to 50 km/h at just 1,250 rpm. The maximum torque of 950 Nm is available on the top model Fendt 620 Vario from just 1,200 rpm to 1,600 rpm and ensures high tractive power and acceleration strength with minimal specific fuel consumption.
