The 150-200hp performance class is one of the biggest in Europe, with machines used in arable farming, grassland, transport, and with front loaders. With the completely newly developed Fendt 600 Vario series, Fendt, for the first time in this performance class, says it is presenting a ‘compact and manoeuvrable four-cylinder tractor with high performance and payload at a low power-to-weight ratio’.
With four models – the Fendt 614 Vario, 616 Vario, 618 Vario and 620 Vario – this new series occupies the 149-209hp (110-154 kW) power range according to ECE R120. For the first time, Fendt DynamicPerformance (DP) added-performance concept is available for all models in the 600 series. DP releases up to 15hp of additional performance on each model via demand-based control exactly when it is needed. For example, the top model Fendt 620 Vario achieves a maximum output of up to 224hp thanks to DP. The extra power concept is not tied to driving speed or special operating tasks. It functions purely dynamically – even when carrying out stationary PTO work or, depending on the operating conditions, during tillage.
All rounder
Designed for global requirements, the development of the Fendt 600 Vario focused on a flexible, manoeuvrable and powerful overall package. It is characterised by a low power-to-weight ratio with a high power range, pioneering manoeuvrability as well as a high payload and a drive concept that seamlessly combines permanent traction, soil protection and low wear for the first time. In addition, there is the optional 60-inch track width for row-crop use and optimum conditions for front loader use.
Exclusively for Fendt, the completely newly developed four-cylinder 5L AGCO Power CORE50 engine enters the market with the Fendt 600 Vario series. Exhaust gas after-treatment takes place via a diesel oxidation catalytic converter (DOC) and diesel particulate filter (DPF) and with selective catalytic reduction (SCR) without exhaust gas recirculation. It meets all required emission standards worldwide. In Europe, this is the Stage V emissions standard. The CORE50 engine is also prepared for alternative fuels, such as HVO, to operate with lower CO2 emissions in future. There are also maintenance-free hydraulic tappets built into the engine. The first engine oil service occurs at 500 hours, so the initial 50-hour interval has been omitted. The newly developed, single-stage Fendt VarioDrive transmission is made up of the engine and the matching VarioDrive drive train.
Transmission tech
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 and simultaneous ground protection with minimum wear and ground-breaking manoeuvrability.
Traction in action
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 and 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 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 1,900rpm. In the main working range, the speed is a quiet 1,350-1,800rpm. The top model Fendt 620 Vario can reach a top speed of up to 50km/h at just 1,250rpm. The maximum torque of 950Nm is available on the top model Fendt 620 Vario from just 1,200-1,600rpm and ensures high tractive power and acceleration strength with minimal specific fuel consumption.
