Optional equipment
4. Front and rear levelling bar
Kit no. 1238370
Levelling bars can be fitted to the front or rear of the
corresponding half-harrow.
Fitting and adjusting the levelling bars.
Front position
The front levelling bars level irregular grounds and help
break up dry clods.
Rear position
The rear levelling bars increase the degree of crumbling
in dry soils and the roller efficiency in sandy soils.
Adjust levelling bars using pins (1).
Adjust levelling bars according to:
- The soil conditions.
- The working depth.
Fit levelling bars so that their angled edges
face towards the machine front (direction of
travel).
The rear levelling bars are not recommended in
wet and sticky soils, and when there are a lot of
stones.
Rear levelling bars increase the machine
horsepower requirement. Remove levelling
bars if they are not required in 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
rollers.
Both half-harrow levelling bars must be set in
the same position.
