Fendt 900 Vario – Technology
Engine technology
The latest technology – the best solution.
Fuel filter for a sure start
When the temperatures outside are icy, the fuel pre-filter guides the pre-heated fuel directly back for injection and not to the tank, until the diesel has reached an adequate temperature. The injection process therefore always runs reliably.
High-capacity reversible fan
The reversible fan on the 900 Vario cleans only as much as is required, and as little as possible. The 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.
Six-cylinder engine with twin-charging
The 900 Vario is equipped with a six-cylinder Deutz engine. The main factor behind the lively and economic engine behaviour is the twin-charging. The set-up consists of a first turbocharger, a charge-air intercooler, a second turbocharger and another intercooler. That ensures that the engine receives plenty of oxygen. And the more oxygen, the more efficient the combustion process.
Three high-pressure injection pumps
Fendt has increased the number of injection pumps from two to three so that 50 percent more power is available. The lower load on the individual pumps ensures a longer lifetime.
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. Exhaust after-treatment is a combination of SCR technology, the passive diesel particulate filter and the 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.
Passive diesel particulate filter with regeneration
New in the 900 Vario is the passive diesel particulate filter, the coated soot filter (CSF), which has been designed for a long working life. Passive means that the filter is regenerated while driving and does not require additional, or active, injection of fuel into the exhaust line. Fendt chose this system to achieve maximum fuel efficiency. The integrated regeneration management guarantees intelligent control of the regeneration cycles.
Efficient SCR technology
The SCR technology is an extremely fuel-efficient solution and has proven itself on the market. Here AdBlue urea solution is injected into the exhaust line and nitrogen oxides are reduced to a minimum. To optimise the AdBlue consumption, it is injected through a 6-fold injector nozzle, which is map-controlled and achieves very fine atomisation. With this technology, operations with the Fendt Vario are highly efficient and environmentally friendly.
Fendt Vario transmission
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
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.
Automatically at the optimum
Important automated functions are included with the stepless drive, ones that further optimise the coordination of the engine and transmission and reduce the operator’s workload. This most important function for this is the fully automatic maximum load control. It regulates the engine speed (engine load) dependent on the power requirement, so that the engine works in the optimal range in terms of fuel consumption and the preset driving speed. There are different optimum values that can be set as the load limit for different operations, for example transport, heavy-duty draft work or for work with PTO-driven implements. The tractor sets the ideal load limit automatically. Operators therefore do not need to set the automatic maximum output control when entering or leaving the field. And the interplay between the engine and transmission is just right for every operation. Alternately, operators can also set the maximum output control manually.
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 multi-function 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 accelerator pedal with two acceleration rates or the joystick with four acceleration rates.
Does it safer.
VarioActive superimposed steering system
With the VarioActive superimposed steering system, a stronger steering ratio can be activated. It adapts itself to the steering movement and ground speed. This is especially convenient at the headlands.
Self-levelling front axle suspension
The hydropneumatic individual wheel suspension is fitted with a double wishbone axle, which optimises the steering angle. The fully automatic levelling control ensures that both sides have the same suspension travel (up to eight tonnes front axle load). Moreover, the entire suspension range can be run through manually. The joints and bearings do not have any lubrication points and are therefore maintenance-free.
Stability control (FSC)
At speeds above 20 km/h, Fendt Stability Control (FSC) locks the compensation between the right and left sides and takes steering precision, driving stability and braking safety to a completely new level. 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.
Driving dynamics with safety and comfort
VarioGrip
The tyre pressure regulation system allows pressure to be controlled while driving. This is accomplished via the integral rotary union, which is designed to last the lifetime of the tractor. Air is supplied via a modified vehicle compressor as well as the vehicle’s own valve equipment. The tyre pressure can be increased by one bar within ten minutes. Reducing pressure by one bar takes only two minutes.

The lighting design concept on the Fendt 900 Vario has been perfected and is state-of-the-art. The dipped and main beams have the newest Bi-LED lamps with headlamp levelling. The work lights and corner lights are also fitted with LED lamps. This permits precise control of the illumination and the visibility to the implements and the wheel arches is outstanding, even in the dark. The LED lamps consume very little electricity and have a very long lifetime.
Coming home light and entry step light
Get back home safely: The light range of the LED headlights can be adapted to the situation at hand, for example for driving on the road. The integrated coming home light permits operators to climb down from the tractor safely, even in the dark. The headlights continue to shine a while longer after the tractor is switched off.
The entry steps on the 900 Vario have practical lights. They are positioned on the tank so that the steps are perfectly illuminated and drivers can climb in and out safely.
Easy and clear operation
The lighting is easily set and adjusted thanks to its straightforward layout. With the smart one-button system, all previously set work lights can be switched on easily and quickly with just one touch of a button in the membrane keypad.
