All advantages in one vehicle: The track tractor system of the new Fendt 900 Vario MT is the result of more than 30 years of experience with track tractors. The wheelbase has been extended by 13 cm to 2,565 mm as compared to the previous versions. The total ground contact area is 3.25 m2 with 25" wide tracks, 3.90 m2 with 30", and a powerful 4.42 m2 with 34". This means: more traction, less soil pressure; an optimal weight distribution across the entire contact area even in the case of a heavy load. And, of course, optimised driving comfort.
You have the perfect setup thanks to our experience.
The widest choice
The rolling tracks establish contact between the tractor and the ground. They are the key to power transmission. A wide range of rolling tracks is available for Fendt 900 Vario MT. There are two rolling tracks, which are specially design for agricultural use, where one version is enhanced for special uses.
Unique suspension system
The Fendt 900 Vario MT offers unprecedented driving comfort for a tracked tractor, which can be experienced during field work as well as on road. This is mainly due to the innovative SmartRide suspension system. Here the hard-bar is mounted on the frame using helical springs, shock absorbers and silent rubber blocks, and has a considerable spring stroke of 217 mm in total. The central carrier can oscillate by 11° for best groundhugging. A coupling rod (Panhard rod) reliably prevents sideways movement, and stabilises the tracks longitudinally.
Full contact for best grip
The three mid-wheels of the track tractor play a decisive role when it comes to permanent power transmission. In the Fendt 900 Vario MT, they are attached to the chassis frame in a unique bogie design. This way they ensure enormous freedom of movement, and make it possible to flexibly adapt the track to the ground contour. Hence the weight is always distributed across a maximum contact area and the entire track is always in contact with the ground. Power can therefore also be permanently transmitted.
The idlers can be weighted down with up to 1580 kg.
Optimal power transmission is ensured by the rear drive wheels, which drive the rolling tracks.
Robust rear axle is built for a very long service life. The internal oil balance can be easily checked through the inspection glasses.
Constantly under tension
The track tractor works through friction-locked power transmission. Perfect traction between the drive sprocket and the treadbar ensures that Fendt 900 Vario MT converts its power into permanent propulsion. A hydraulic cylinder mounted on the chassis frame pushes the idlers forward and thus creates tension so that traction is never lost. Since the tensioning system works in one direction, the bearings are reliably protected thanks to the symmetrically acting forces. The right pressure is set automatically; it is comfortably controlled via the Varioterminal 10.4".
Always clean on the track: Guide wheel
The front guide wheel keeps the Fendt 900 Vario MT clean on the track. It is 950 mm in diameter. The guide wheel is also offered in two different widths for different rolling track widths. The correct width supports selfcentring of the rolling tracks. The rubber coating of the idlers provides reliable contact with the treadbar.
Unique design: Mid-wheels
Another unique feature that will let you experience the huge benefit of a track tractor is the oscillating rollers. The three rollers are 355.6 mm in diameter and are attached to the chassis via a unique bogie in bogie suspension system called Constant Grip. The special polyurethane coating of the snap-in ring inside the rollers reliably prevents heat generation even during continuous operation at high speeds. It also protects guide blocks inside the rolling tracks.
Keep moving forward: Traction wheel
The traction wheel has once again been improved in the latest evolution stage of the track tractor. It is 1550 mm in diameter and has a special coating with a chevron pattern. The surface offers good self-cleaning properties and thus prevents accumulation of dirt. This results in reliable traction. There is a debris ejector on the inside, which prevents contamination in the rim after every turn.
Thanks to the innovative SmartRide suspension concept, Fendt 900 Vario MT offers unparalleled ride comfort for a track tractor.
Even on headlands, the track system shows its strength and does not create deep tracks.
