All advantages in one vehicle: The track system on the new Fendt 900 Vario MT is the result of more than 30 years of experience with track tractors. The wheelbase has been extended to 101 inches; 5 inches longer than previous versions. The total ground contact area is 35 ft² on 25" wide tracks, 42 ft² with 30" and a hefty 47.6 ft² on 34" tracks. This means: more traction, less soil pressure and an optimal weight distribution across the entire contact area even in the case of a heavy load. And, of course, optimized driving comfort.
You have the perfect setup thanks to our experience.
The widest choice
The tracks establish contact between the tractor and the ground. They are the key to power transfer to the ground. A wide range of tracks are available for the Fendt 900 Vario MT. There are three tracks, two which are specially designed for agricultural use, and one which is enhanced for extreme applications.
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 coil springs, shock absorbers and silent rubber blocks. With a considerable spring stroke of 8.5 inches, the hard-bar can oscillate by 11° for best ground following. A coupling rod (track bar) prevents any movement to the side and stabilizes the tracks lengthways.
Full contact for best grip
The three mid-rollers of the undercarriage play a decisive role when it comes to permanent power transmission. On Fendt 900 Vario MT, they are suspended from the roller frame in a unique boogie-in-boogie system. This way they achieve an enormous swing distance and 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 3,500 lb.
Smoothly driving the MTS, the rear drive wheels transfer the power perfectly.
The durable rear axle is built for the longest service life. The internal oil level can be easily checked through the sight glass.
Constantly under tension
The tracks run smoothly, without any friction. Perfect traction between the drive wheels and the rolling track ensures that the Fendt 900 Vario MT converts its power into permanent propulsion. A hydraulic cylinder mounted on the undercarriage 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 hydraulic accumulator automatically sets the right pressure. This is clearly displayed on the 10.4" Varioterminal.
Always running in line: Idler wheel
The front idler wheel keeps the Fendt 900 Vario MT running in line. It measures 37.4 inches in diameter. The idler wheel is also offered in two different widths for different track widths. The correct width supports self-centering of the tracks. The rubber coating of the idlers provides reliable contact with the belt.
Unique design: Rollers made from polyurethane
Another unique feature that will let you experience the leading edge of the tracks is the oscillating rollers. The three rollers are 15 inches in diameter and are attached to the roller frame via a unique boogie-in-boogie suspension system called ConstantGrip. 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.
Ensures your progress: Drive wheel
The drive wheel has once again been improved in the latest evolution stage of the track drive. It measures 61 inches in diameter and has a rubber coating with a chevron pattern. The surface offers good self-cleaning properties and thus prevents accumulation of dirt. This results in reliable traction. The optional debris ejector on the inside prevents buildup in the rim after every turn.
The mid-rollers, drive wheels and idlers are fitted with different widths for perfect tracking depending on the width of the track.
Even on headlands, the track tractor shows its strength and does not create deep tracks.
