Adjusting the coulter pressure hydraulically

On a field with light (sand) and heavy (clay/loam) soils, the coulter pressure can be adjusted during operation. Two pins in an adjuster segment act as the stop for the hydraulic cylinder.

The scale 1 serves as orientation for adjusting the pins.

  1. To define the maximum coulter pressure:

    Insert the pin 2 in the top row in the desired position.

  2. To define the minimum coulter pressure:

    Insert the pin 1 in the bottom row in the desired position.

  3. To increase coulter pressure:

    Actuate the green 1 tractor control unit

or

To reduce the coulter pressure:

put the green tractor control unit into float position.

The mechanical coulter pressure display on the machine shows the set coulter pressure.

  1. To check the setting:

    Seed for 30m at working speed and then check the work pattern.
