Optional equipment
7. Front or rear levelling bar
HR4004D: Kit no. 1238680
HR4504D: Kit no. 1238690
The levelling bar can be fitted to the front or rear of the
machine.
Fitting and adjusting the levelling bars.
Front position
The front levelling bar levels irregular grounds and helps
brake up dry clods.
Rear position
The rear levelling bar increases the crumbling degree in
dry soils and the roller efficiency in sandy soils.
- Remove lock pin (2).
- Use crank (1) to adjust levelling bar height.
Adjust levelling bar according to:
• The soil conditions.
• The working depth.
- Reinstall lock pin (2).
Fit levelling bars so that their angled edges
face towards the machine front (direction of
travel).
The rear levelling bar is not recommended in wet
and sticky soils, and when there are a lot of
stones.
The rear levelling bar increases the machine
horsepower requirement. Remove levelling
bar if it is not required at work.
The height adjustment is correct when the soil
flow hits the rear levelling bar. Make sure there is
enough clearance between the lower edge and
the ground to allow soil to move towards the
roller.
Adjust both sides to the same setting.
