Spread rate check (determining the calibration factor)
AmaSpread+ BAG0126.4 09.17
8.1 Performing a spread rate check with the fertiliser chute
• For the spread rate check, the calibration factor for the spread
material is determined for
ο the implement coupled to the tractor,
ο dismounted spreading discs,
ο driven universal joint shaft,
ο stationary tractor.
DANGER
Risk of injury from rotating spreading discs!
Dismount both spreading discs before determining the calibration
factor.
1. See operating manual for the implement. →continue.
→ The spreading quantity applied during the rate check must be
completely collected.
2. Add a sufficient quantity of spreading material to the hopper.
3. Remove both spreading discs.
4. Check the calibration factor from the setting chart in the Settings
menu and correct if necessary. →continue.
5. Switch on spreading disc drive. →continue.
6. Open the left shutter.
→continue.
7. When the bucket is full, close the left shutter.
→continue.
8. Switch off the spreading discs.
9. Weigh the collected fertiliser quantity.
• The scale used must have the
corresponding weighing accura-
cy. Large inaccuracies may
cause deviations in the actually
applied spread rate.
• Take account of the weight of the
bucket.
10. Enter the value for the collected fertiliser quantity in kg.
The calculated applied fertiliser quantity will be displayed.
→continue.
11. The calibration factor will be calculated and displayed.
12. Save calibration factor, or
discard calibration factor.
