profi 10/2003 Star athlete with anideal weight “the chassis on the 818 Vario TMS leaves no wishes open” “its driving comfort is unbeatable compared to many other standard tractors.” 6 6 7 1 Frame and suspension concept All suspension elements are mounted on the frame construction (1). Front axle suspension: swing arm (2), swing axle (3), hydraulic cylinder (4), nitro- gen reservoir (5). Cab suspension: hydraulic supports (6) at the front, helical springs (7) and shock absorbers (8) at the rear (sprung struts) control the movement of the cab and elimi- nate vibrations and shockloads originating from the tractor body. Result: quiet and relaxed working conditions. 2 3 4 NEW:
Pneumatic cab suspension Oil-filled hydraulic supports in the front stabilize the cab in the front-to-rear direction and absorb noise. The new pneumatic cab suspension features air springs that support the load at the rear. These feature automatic levelling, which automatically adapts the suspension to varying loads. Setting different suspension levels is no longer necessary. Your benefit: advanced, permanently relaxed driving comfort in the field and on the road. 3 Front axle suspension The swing axle centrally located in the swing arm detects uneven surfaces and transmits these findings to the swing arm.
The plungers on the two cylinders displace oil, activating three nitrogen reservoirs which absorb all shocks. Speed-dependent shock load stabilizing system This system acts like a hydraulic shock absorber. Activation can be controlled via the Vario terminal. Even with a rear-mounted implement, the operator enjoys a comfortable and safe ride without a reduction in speed, and most importantly, without stress- ful bounce, on the road or in the field. Mudguards on the front wheels can be swung out to maximise steering angle. 23 4 5 1 2
