Spreading on slopes has a major impact on the spreading pattern. This is partly caused by the spreader tilting.
The following issues require attention when spreading on slopes:

  • When spreading a field containing slopes, do not choose a large working width. Do not spread too wide on steep slopes.
  • In the case of boundary spreading, it is often the case that if you spread at an angle to the hill, you will spread further downhill than uphill. You can prevent this by using a hydraulic spreader to adjust the speed of the discs;
  • With some spreaders, spreading on slopes has an adverse effect on the spreading pattern. This is caused by the fertiliser ending up in a different place on the spreader disc;
  • If you use a weighing spreader on slopes, the weighing system may no longer work accurately as the weighing cells of the spreader are affected when you spread at an angle to the hill. The reason for this is that the fertiliser is unevenly distributed in the hopper. This can be prevented by means of an inclination sensor. This sensor then makes a correction;
  • When you are spreading on hills, it is advantageous to use a speed-dependent dosing system, as it allows slip to be detected when you drive uphill.
