The new Fendt 900 Vario MT tracked tractors are available in three output levels: Fendt 938 Vario MT with 380 HP, Fendt 940 Vario MT with 405 HP and Fendt 943 Vario MT with 431 HP (ECE R120).
The tracked tractors in the Fendt 900 Vario MT series (Mobile Trac) are especially efficient in covering large areas, and feature a whole new level of ride comfort, based on a completely new innovative suspension concept.
A unique tracked suspension concept
Vastly improved handling on the road and in the fields was a key objective of the development work on the Fendt 900 Vario MT. The new suspension concept consists of four elements; an air-sprung operator's seat, 2-point cab suspension, the new SmartRide primary suspension, and the reworked drive with ConstantGrip suspension.
ConstantGrip: The three middle track rollers are fitted in the track frame via the pendulum suspension (bogie in bogie). This allows the track rollers to be adjusted to follow the ground contours in the fields and on the roads. Other benefits include an even weight distribution over the entire treadbar surface and maximisation of the contact area in the fields.
SmartRide: The main beam for the drives is connected to the chassis by the newly developed suspension. The suspension consists of:
• Sturdy helical springs with integrated pressure surge dampers
• Additional hydraulic shock absorbers for damping if bouncing occurs
• Hydraulic shock absorbers and spring pads guarantee optimal suspension behaviour when bouncing occurs, and limit the spring travel
• The torque rod stabiliser bar provides the chassis with lateral stability.
This results in a significant longer spring travel of 260 mm in total (measured on the front guide wheel). The suspension allows a swing angle of 11° on each drive, and is therefore comparable with the front axle suspension of a wheeled tractor.
The Fendt 900 Vario MT is the first conventional tracked tractor with a 2-point cab suspension, consisting of two dampers with rubber buffer on the front and helical springs with integrated shock absorber on the back.The total spring travel on the cab rear is 98 mm and provides ver...
