Calibration; Magnesium Oxide - C-Dax C-DIT400GT Owner's Manual

1. Ensure the control handle is fully back (clutch disengaged, shutter closed).
2. To calibrate your spreader, place a measured amount of product (10 Kg) in the hopper.
3. Set the Shutter Stop Lever to the position (1-9) indicated in the Calibration Guides below.
4. Tow the spreader at the desired speed and pull the control handle forward to engage the clutch and
open the shutter.
5. When the product has been exhausted, measure the distance covered and band width in metres. It is
recommended that this be done over an area where the product can be seen on the ground so that the
spread width can be measured.
6. Check the application rate using the following formula:
Rate (Kg/ha) =
7. Adjust either the Shutter Stop Lever or the speed of travel until the desired application rate is achieved.
Because of variations in product characteristics, speedometer calibration and driving speed, the information
in the calibration guide should be regarded as a starting point only. It is recommended that the spreader be

Magnesium Oxide

Magnesium Oxide powder is applied at a rate determined by the number of cows to be treated. When
spreading this product, calculate the weight of powder to be applied and apply this amount using shutter
setting 4 or 5. Because this product may set hard if left exposed to air, it must not be stored in the machine
even for a short time. Load the spreader only with the amount required to be spread and clean all traces of
product from the machine after use.
