5.9.2 Extra coverage following harrow pressure
The pressure of the extra coverage following harrow
depends on the kind of soil. On lighter soils, operate
with less extra coverage following harrow pressure
than on heavier soils.
The two pins (Fig. 117/2) in the setting segment
function as a stop for the lever (Fig. 117/1) and limit the
swivelling range of the lever.
The higher you insert a pin in the hole segment, the
higher the harrow pressure will get.
The normal harrow pressure is adjusted via the lower
pin.
The increased harrow pressure is adjusted via the
upper pin.
Carry out equal adjustments on
- 1 Setting segment (Cirrus 3000)
- 3 Setting segments (Cirrus 4000)
- 3 Setting segments (Cirrus 6000).

5.9.2.1 Setting the normal harrow pressure
Setting the normal harrow pressure:
- Select harrow pressure key in and by actuating the control
valve 1 pressurise the hydraulic ram.
- Stop the tractor engine, apply the parking brake and remove the ignition key.
- Insert the pin into a hole in the setting segment below the lever and secure using a
linch pin.
- Actuate the harrow pressure key in and switch the control
valve 1 into its floating position.
5.9.2.2 Setting the increased extra coverage following harrow pressure
Setting the increased harrow pressure:
- Select harrow pressure key in and switch control valve 1 into
the floating position (hydraulic ram without pressure).
- Stop the tractor engine, apply the parking brake and remove the ignition key.
- Insert the pin in a hole in the setting segment above the lever and secure using a
linch pin.
Hint!
Drive approx. 30 m and recheck the operational performance of the normal and
increased extra coverage following harrow. Readjust if necessary.
