Calibrate your Spreader easily, fastly and exactly.
Your spreader doesn´t, what you want to do? Then it´s time to use Cali Calc:
First you select or create your spreader. Set the working speed and fertilizer dosage in kg/ha.
Then you set the spreaders output like described in its manual.
Check the expected output of the spreader (only one side) with the built in stopwatch. If necessary tune the spreader and you are ready to go.
