Precise depth control

The ground needs to be tracked with precision to ensure optimum depth control, so that the TERRADISC can maintain a consistent working depth. The TERRADISC does this using jockey wheels mounted in front of the discs, the chassis wheels, and the wide support surface of the rear roller.

1 Chassis for central depth control

2 Dual jockey wheels on the frame sections

3 Wide ground tracking using the rear roller

The working depth is adjusted hydraulically. This enables the depth to be set with precision between 5 cm and 15 cm to optimally fulfil the different requirements of each processing step.


Large jockey wheels

Together with the chassis, the leading jockey wheels help maintain a consistent working depth by tracking undulations in the ground in front of the TERRADISC. These dual jockey wheels are fitted with 340/55-16 tyres to provide a sufficient area of contact for ground tracking. The jockey wheels are fitted as standard starting from a working width of 10 m.


Transport chassis

The transport chassis is the first stage of ground tracking, guiding the central height of the TERRADISC. In addition to the single axle, the TERRADISC HT 12000 is also available with a tandem floating axle, which can compensate for small bumps in the ground more precisely.


Rear roller damping system

The TERRADISC rear rollers are equipped with damping cylinders to ensure smooth running and prevent the TERRADISC from jolting. The damping system reduces vibrations and jolts caused by bumps so that the TERRADISC runs smoothly over the soil without bouncing, making it easier to maintain a consistent working depth. The damping cylinders can be controlled hydraulically to match the soil conditions.


Working depth adjustment

On the standard version, the depth is set using the hydraulic cylinders with swing clips. This ensures simple and reliable adjustment of the working depth. By rotating the clips in or out on the cylinders of the jockey wheels and the rear rollers, the working depth can be finely adjusted in 9 mm steps between 5 cm and 15 cm.

Using the Profiline comfort control system, which is available as an option, infinitely-variable working depth can be conveniently controlled from the cab using ISOBUS.

Because the rear rollers are in a straight line, all frame sections can be set in the same way.
