Pulls more. Does it more efficiently.

Fundamental innovations have found their way into the Fendt 900 Vario, ones that further improve the efficiency of the tractor series. The primary innovation is the combination of new engine technologies with the optimised continuously variable Vario transmission – here the best of the best come together. Lively handling through greater dynamics, higher torque and improved power availability. At the same time, intelligent solutions, such as the tractor management system TMS, ensure low consumption of both fuel and AdBlue.

Constantly achieve more.

Can do more with twin intercooler

The air that has been pre-compressed in the low pressure turbocharger is cooled down by an additional charge-air intercooler, before it is further compressed in the high-pressure turbocharger. Thus the engine can take in a larger air mass with the same volume, which also means more oxygen. This results in more efficient fuel combustion and improved performance.

Fuel efficiency thanks to low rated speed

The engine performance allows the rated speed to be reduced to 2,100 rpm. This not only further improves fuel efficiency, but also provides for a pleasantly low noise level.

More dynamics thanks to twin turbocharger

Fendt 900 Vario provides enormous power and dynamic acceleration with a maximum power of up to 396 hp. With two turbo loaders and Common Rail high-pressure injection the 7.8-litre Deutz engine provides immense tractive power. A high injection pressure of 2,000 bar ensures fine atomisation and therefore the best combustion in the engine.

The reversible fan can reverse the air stream automatically, so the cooler elements are effectively blown clean. What's special: Depending on the cooling requirements, the position of the fan blades is adjusted to increase the cooling efficiency. This has a positive effect on fuel efficiency.

The high-grade solution for extremely low operating costs: the combination of external exhaust gas recirculation (AGRex), passive diesel particulate filter (CSF) and SCR technology.

Engine characteristics – Fendt 939 Vario

Through the well-rounded torque curve, more power is already available in the lower speed range. Furthermore, the constant power range provides a broader engine speed band over which the maximum power can be called up. In this range, the rated speed is equivalent to the maximum power.

Exhaust technology

Optimal solution for Tier 4 final

The intelligent solution for compliance with the new Tier 4 final emissions standard is decisive for the economy of the drive train. That is why Fendt has equipped the engine with an exhaust after-treatment that enables the lowest fuel and AdBlue consumption. This exhaust after-treatment features a combination of SCR technology, a maintenance-free, self-regenerating passive diesel particulate filter and AGRex exhaust gas recirculation.

AGRex external exhaust gas recirculation

In the first step, exhaust gas recirculation reduces nitrogen oxides before they enter the exhaust line. Therefore only a small injection of AdBlue is required to reduce nitrogen oxide emission to 0.4 g/kWh. The lower AdBlue consumption has a positive effect on the profitability and efficiency of the tractor.

AGRex external exhaust gas recirculation

The external exhaust gas recirculation ensures that the nitrogen oxides NOx are already reduced before they reach the exhaust line. That is more economical, because less AdBlue is required in the exhaust line to further reduce the nitrogen oxides.

Steplessly efficient.

For years now, continuously variable transmissions have proven their leading efficiency and performance and have become the first choice. Operators are always in the position to work at the optimal speed, which means considerable savings potential. You save valuable working time in different operations through higher area coverage and also profit from low fuel consumption.

Perfect settings and driving strategies

Thanks to intelligent pre-settings, it is easy to perform work. For example, engine speed and cruise control speeds can be pre-programmed in the Varioterminal and easily activated during operation using the multifunction joystick – especially practical for PTO work, for example. The different driving strategies are also adapted to operations and individual preferences. Drivers can control the speed with either the joystick with four acceleration rates or the foot pedal.

Automatically at the optimum

Important automated functions are included with the stepless drive, to further optimise the coordination of the engine and transmission and reduce the operator's workload. The most important function for this is the fully automatic maximum output control 2.0. It regulates the transmission ratio dependent on the preset speed and the power demand, so that the engine speed is lowered into the range of optimal fuel consumption. There are different optimum values that can be set as the load limit for different types of work, such as transport, heavy-duty pulling or for work with PTO-driven implements. The tractor sets the ideal load limit automatically. Operators therefore do not need to actively adjust the maximum output control to each operation. And the interplay between the engine and transmission is just right for every operation. Alternately, operators can also set the maximum output control manually.

The Fendt Vario transmission is a hydrostatic-mechanical power split drive. With increasing speed, the share of the mechanical power transmitted through the planetary set increases. The hydrostats can be swung 45 degrees and have a high operating pressure of max. 550 bar – this ensures exceptional efficiency.

Continuously variable Vario transmission ML 260

The transmission on the top models over 330 hp have been designed for the highest loads. It has a set of four planetary gears, which optimises power transfer and results in high robustness.

Can do it faster. Does more.

Maximum on-road and in-field driving safety

With the unique Fendt Stability Control FSC you always have a safe feeling when driving, even in curves. At the same time, the practically maintenance-free braking system, comprising wet multi-disc brakes for the front and rear wheels, provides high driving safety and excellent deceleration. The intelligent brake light control activates the brake lights and warns the traffic behind you that you are decelerating, even when the brake pedal is not pressed.

Does it safely

Speed is a must for transport work – exactly the right thing for the new Fendt 900 Vario. It is optionally available with a top speed of 40, 50 or 60 km/h. And with this high-horsepower tractor, you will reach your destination safely: equipped with the latest safety systems for tractors, such as ABS or the automated steering axle for the trailer with self-steering axle, driving the 900 Vario is now even safer.

ABS – for the highest level of braking safety

The ABS module measures the speed on each individual wheel using four speed sensors and compares these in the control unit. If the speed on one wheel is too slow when braking, e.g. due to different surfaces, the ABS automatically opens the corresponding brake to prevent the wheel from locking. Since the wheels on a tractor have different sizes on the front and rear axles and they have high torque of inertia through their weight, the ABS module also communicates with the tractor control unit.

Haul 37 tonnes more a day

The Fendt 900 Vario convinces with up to 16% higher transport capacity* through a top speed of up to 60 km/h at a fuel-saving 1,750 rpm. Those are advantages that make the difference at the end of the day: for example, a Fendt 900 Vario with a transport capacity of a total of 230 tonnes in ten hours moves 37 tonnes more thanks to the higher speed. And when the Fendt 900 Vario is driven at 50 km/h and an engine speed of 1,450 rpm, it saves even more fuel.


* in-house measurement

Driving dynamics with safety and comfort

The hydropneumatic independent wheel suspension is fitted with a double wishbone axle, so each wheel is suspended individually, which ensures maximum comfort and the best traction. This prevents power-hopping during heavy draft work. The fully automatic levelling control ensures that both sides have the same suspension travel with up to eight tonnes front axle load. Furthermore, the 300-mm suspension travel can be run through manually when standing still, e.g. for picking up a front weight without front linkage.

In relation to the standard setting, with VarioActive one only needs approx. 60% fewer turns of the steering wheel for the same wheel angle. With VarioActive, you profit through the faster reaction of the steering during tight turning manoeuvres at the headlands. For reasons of safety, it can only be used from 0 – 25 km/h.

The Fendt 900 Vario is equipped with an ABS anti-lock braking system. The tractor can be steered and controlled better, even when braking sharply on wet or loose surfaces.

Fendt Stability Control (FSC)

Fendt Stability Control (FSC) provides additional stability and steering precision when driving above 20 km/h on the road. When the driving speed drops below 15 km/h, compensation between the left and right side is possible again, which guarantees the best ground contact.
