Technology | Fendt 900 Vario MT

Reliably converts every drop of fuel into efficient power.

Fendt iD low engine speed concept

A powerful and highly efficient 7-cylinder AGCO Power engine sits under the bonnet of the Fendt 900 Vario MT. With its cubic capacity of 9 litres, the engine generates up to 317 kW/431 hp at a rated speed of just 1700 rpm. Two in-line turbochargers with fixed geometry provide constant power generation. The max. torque of 1.921 Nm is already reached at just 1,450 rpm thanks to the Fendt iD low-speed concept. The speed range of the engine is between 1,000 and 1,700 rpm. The engine idle speed is just 800 rpm. Experience unbridled power and extremely efficient work during every use thanks to Fendt iD.

Economical, low-emission, environmentally friendly

The Fendt 900 Vario MT fulfils the strict emission regulations Stage V/Tier 5. With the injection pressure of 2,000 bar, combustion is extremely clean. With a low particlate volume. The electronically controlled and cooled exhaust gas recirculation recirculates a small part of the exhaust gases back to combustion. Part of the exhaust aftertreatment is a new 'all-in-one' exhaust system, which includes a diesel oxidation catalyst and a diesel particulate filter. The pressure drop on the filter measures the amount of particles that pass through the system. This is followed by the SCR catalyst, which is located in the upper part of the exhaust. The exhaust is located on the right side of the vehicle, so the view to the front is not obstructed.

Unique cooling system

Efficient cooling is ensured by the unique Fendt Fan and Concentric Air System (CAS) cooling concept. Here, a forced-draft high-performance fan is positioned in front of the cooler unit, where it sucks in cool dense air, accelerates it via the concentric hood and pushes it through the cooler. The CAS has its own hydrostatic drive, so it can always deliver ideal cooling power to each component according to need, independent of the engine speed. The fan is tilted upwards, which prevents harvesting residue from being sucked up from the ground.

Easy maintenance for long operating times

Do not waste time on extensive maintenance. Take advantage of the long maintenance intervals and perfect accessibility. Fresh air is sucked in at the front. The Venturi system of the air filter prevents many dirt particles from getting sucked in. In addition, a dust extraction system, which is driven by the vacuum of the CAS, ensures that the air filter remains efficient for longer periods. A contamination sensor constantly monitors the status of the filter and reports upcoming maintenance if required. The constant further development of AGCO Power engines along with the low maintenance effort makes Fendt 900 Vario MT a totally reliable workhorse.

Two turbo chargers with fixed geometry and electronic wastegate control provide enormous torque across the entire speed range.

The fuel filter is very easy to reach for routine maintenance.
A large intercooler with a heat exchanger as an intermediate intercooler ensures perfectly temperature-controlled inlet air.
Two turbo chargers with fixed geometry and electronic wastegate control provide enormous torque across the entire speed range.

The Concentric Air System offers a large cooling capacity with maximum efficiency along with an unparalleled high efficiency.

The air filter is easy to replace and has a dirt sensor, which provides information on the filter effect.

Fendt VarioDrive: Drive of a new generation.

Vario gearboxes of the latest generation

The revolutionary Fendt VarioDrive drivetrain from the standard tractor Fendt 1000 Vario has been extensively and optimally adapted for the Fendt 900 Vario MT. The result was the innovative and efficient continuouslyvariable drive for tracked tractors, which fulfil all the practical requirements. As a result, you can drive in a continuously-variable power-split way in a speed range from 20 m/h to 40 km/h and without having to manually change between the speed ranges. You can therefore always work within an optimal speed range with minimum slippage when operating the Fendt 900 Vario MT. What you experience is huge power transmission and the best jerk-free ride comfort.

High-performance hydrostatic devices

The heart of VarioDrive drivetrain is formed by the extremely large and powerful hydrostatic devices. They each boast a capacity of 370 cm3. The hydro-motors can swivel independent of each other. This way, the VarioDrive drivetrain achieves maximum efficiency in every situation. To further increase the efficiency, a hydro motor is decoupled at higher speeds (more than approx. 20 km/h) as soon as it swivels back.

Automatic in optimal range

Thanks to the Fendt VarioDrive drive, you can always drive automatically within the most efficient range. The Fendt 900 Vario MT achieves a transport speed of 40 km/h at a low 1,550 rpm. The renowned Tractor Management System TMS along with the automatic maximum load control ensures that the Fendt 900 Vario MT delivers the most efficient results every time, without you having to make any elaborate settings. Together with Fendt iD low engine speed concept, experience sheer power with lowest possible consumption.

Everything under one roof

It was never easier to control a tracked tractor to perfection. For Fendt 900 Vario MT, the motto is: Sit down and set off. Select your preferred driving strategy in the armrest: Drive the Fendt 900 Vario MT using either the joystick or the accelerator pedal. In the process, the TMS maintains an optimal ratio of the rpm and driving speed. You can also set the rpm with the accelerator pedal and the speed using the joystick. If the TMS is deactivated, you can control the speed and the engine speed absolutely independent of each other.

High-performance hydrostatic devices in the Fendt VarioDrive ensure smooth acceleration and efficient jerk-free propulsion.

Attachments under complete control

Matching the power and performance of Fendt 900 Vario MT, the hydraulic system has also been developed for maximum performance. Select either 220 l/min or 440 l/min pump capacity. The bigger version has two separate circuits with 220 l/min capacity each. Both the versions deliver their maximum performance at 1,700 rpm. The highest extractable oil quantity is 100 litres. And the hydraulic oil supply is separate from the transmission oil. This avoids mixing the oil and causing system problems. The steering system has its own separate system. This means that there is enough oil at your disposal for the attachments.

Interfaces at the rear

Both hydraulic pumps share the work perfectly; one of the pumps is directly coupled to the left valve block and supplies to valves 1-3 and the Power Beyond connection. The second supplies to the right valve block with valves 4-6 and the powerful linkage. All in all, maximum six valves are possible in the rear. Stay flexible with cartridge applications: the 1/2" couplings offer a flow rate of up to 140 l/min. The 3/4" coupling and easy Flat Face Coupler (FFC) allow up to 170 l/min. All the valves at the rear can be coupled under pressure on both sides (DUDK)

Complete lifting unit

You can couple three-point attachments onto the Fendt 900 Vario MT just as comfortably as onto a standard tractor. The rear linkage has a 11,500 daN lift capacity. In addition to power, enjoy the greatest comfort: the rear linkage can be operated at both the rear mudguards. shock load stabilisingdamping when driving on road contributes to high ride comfort and road safety. Gearbox pressure sensors are used for controlling the linkage. You can control the attachments perfectly via the comfortable power lift module in the armrest.

Direct power transmission

In order to transmit power of the AGCO Power engine to the PTO-operated attachments efficiently, the PTO is almost directly connected to the crankshaft. Only one gear level lies in between. This facilitates high effectiveness. Two speeds are at your disposal: The 1000 at 1,650 rpm or the 1000E at a favourable 1,255 rpm. The speed is pre-selected simply and without complication at the touch of a button in the cab. The PTO is similarly activated. Alternately, it can also be activated at both the rear mudguards.

The hydraulic connections are marked in colour. This way, you can couple devices quickly and safely.
