Adjusting the coulter pressure hydraulically

The coulter pressure can be adapted to the soil during operation when changing to heavy or soft soil. 2 pins in an adjuster segment act as the stop for the hydraulic cylinder.

  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.

NOTE

The adjustment of the coulter pressure must be adapted to the respective operating conditions. The optimum adjustment can only be determined during field operation.

  1. To check the setting:

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