    Operation 11.18 Depth wheel and depth and transport wheel The plough can be supplied with a depth wheel (1) or depth and transport wheel. The depth and transport wheel must al- ways be used if the front axle - particularly during road transport - is relieved too much and this results in inadequate steerability of the tractor.

  • Page 121 Overload safety devices Once the adjusting valve unit has been connected to a tractor spool valve, the sys- tem is ready for operation with the factory- set maximum and minimum operating pressure. These operating pressures can be adjusted to meet individual require- ments using the rotary knobs (2 and 3).

  • Page 122: Operation

    Overload safety devices 12.3.3 Operation To protect the hydraulic system, the plough and the tractor itself, always work at the lowest possible operating pressure. The maximum operating pressure is set by applying pressure to connection A on the valve adjusting unit for several seconds. The minimum operating pressure is set by applying pressure to connection B on the valve adjusting unit for several seconds.
