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.
WARNING
Unexpected movement of the coulter and exact following harrow
The hydraulic cylinders for the coulter pressure adjustment and the exact following harrow pressure adjustment are actuated simultaneously.

Before you actuate the tractor control unit,

direct people out of the danger area.
  1. 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 implement shows the set coulter pressure.

  1. To check the setting:

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