IMPORTANT

Do not over-bend the flat spring!

The flat spring tension must securely retain the main and extension vanes on the spreading disc. If the flat spring is over-bent it loses its necessary tension for securing the spreader vanes.

If the spring tension is too low the locking pin disengages and can cause severe material damage.

When adjusting the spreader vane position, push the locking pin care-

fully into one of the position holes.

Check the spring tension at regular intervals. See

8.2.3: Check the flat areas of the spreader discs, page 84 .

If the spring tension is too low replace the flat spring immediately.

Information on the hopper height

Maximum approved hopper height at front (F) and rear (R)

The maximum approved hopper height (F + R) is measured from the

ground to the bottom edge of the frame.

Hopper heights A and B as per the fertiliser chart

The hopper heights in the fertiliser chart (A and B) are always measured in the field from the top of the plant stand to the bottom edge of the frame.

NOTE

The values of A and B are taken from the spreading charts.

CAUTION

Setting hopper height

Risk of injury by rotating spreading discs!

Contact with the broadcast equipment (spreading discs, vanes) may injure, crush or cut off body parts. Body parts or objects may be caught and pulled in.

X

Never exceed the maximum approved hopper heights at the front (F) and rear (R).

Proceed as follows when determining the hopper height (in normal dressing):

1 Set the hopper heights A and B (above crop) from the calibration charts.

2 Compare the hopper heights A and B (plus the plant stand) with the maximum approved hopper heights at the front (F) and rear (R).

The following applies: A + plant stand

≤

F

B + plant stand

≤

R

3 If the maximum approved hopper height of the solid fertiliser broadcaster for normal dressing is exceeded or hopper height A and B can no longer be reached, the solid fertiliser broadcaster must be set up with the values for late top dressing.
