Hydro-pneumatic chassis – high-performance in the field and on the road

The hydro-pneumatic suspended chassis, in combination with the sprung drawbar, provide perfect driver comfort. The BPW axle assemblies, with standard fill level regulation, continuously adapt to the load conditions. The sprung drawbar has a high support load of 3 t and, in combination with the ball coupling (K80), facilitates strong traction by the tractor and smooth running of the machine. The machine has high rolling stability since the suspension cylinders are connected crosswise. The enclosed hydraulic system always ensures an equal load distribution to all 4 wheels. Possible track widths range between 2.00 and 2.25 m, and the wheel diameter can be up to 1.95 m.

Traction control

The UX 11201 Super excels in difficult hilly terrain: traction control of the hydro-pneumatic axle suspension facilitates a temporary increase of the support load on the drawbar from 3 to 4 t when the machine is full. If the machine is partially full, the support load is increased by up to 30 %.

SingleTrail passive steering

The chassis of the UX 11201 Super has passive rear axle steering as standard for good handling and reduced track damage. The SingleTrail passive steering has a rigid front axle and a steered, passively trailing second axle, which results in good handling without skidding the wheels.

When reversing, the second axle has to be locked. In road transport it should also be locked as well. In tight turns and slow travel, the axle can be unlocked.

DoubleTrail - fully automatic axle pivot steering

The UX 11201 Super can also be equipped with the electronically-controlled DoubleTrail axle steering system as an option. This electronic positive steering of both axles is particularly important for row crops, such as potatoes, beet and small field sizes, in order to avoid track damage.

The first axle now runs consistently in the tracks of the tractor rear wheels and the second axle follows the tracks of the tractor front wheels. A high level of directional stability with respect to the tractor is achieved and, more importantly, the sprayer boom is not negatively affected by the steering movements. During road transport, the first axle is locked and the second axle is actively steered by the system.
