8.10.1
Exact harrow – spring tine position
Set the spring tines of the exact harrow in such a
way, that they
•
are placed parallel on the ground and
•
can move 5 - 8 cm downwards.
The distance between the exact harrow and the
soil is then from 230 to 280 mm (Fig. 92).

The setting is achieved by lengthening or short-
ening the upper harrow suspension (Fig. 93/1):
1. Putting the machine into operation in the
field.
2. Stop tractor engine, apply parking brake,
remove ignition key.
3. Slacken the counter nut (Fig. 93/2).
4. Adjust the upper harrow suspension on all
fixing points (Fig. 93/1) to an equal measure
of length. For this turn all bolts (Fig. 93/3)
equally.
5. After setting, retighten the counter nut (Fig.
93/2) firmly.
6. Check the working result of the exact har-
row.

Exact harrow pressure
Warning!
Actuate the control valves only from inside the tractor cab!
When actuating the control valves several hydraulic rams may
start functioning, depending on the switching position!
Advise people to leave the danger area!
Danger of injury from moving parts!
The exact harrow pressure is set with the aid of pins. The higher the
pin will be inserted in the setting segment, the higher the harrow pres-
sure will be.
Exact following harrows with hydraulic pressure adjustment are pro-
vided with two pins for different kinds of soil.
Carry out the same setting on all setting segments.
