Spreading rate calculation
Four parameters are needed to determine a spreading rate: the volume of
manure, the time needed to spread the manure, the tractor speed and the
spreading width.
Determine which type of measurement unit (imperial or metric) you prefer and
follow the instructions.
Warning!
Do not tow this product at a speed exceeding 40 km/h.
Before calculating the spreading rate, test the product and note the parameters
described below:
● Fill the spreader tank with liquid manure.
● Note the volume of manure inside the spreader tank.
● Move to a spreading area.
● Position the tool bar to spread.
● Move the spreader at a constant speed.
● Spread the manure and monitor the time it takes for the spreader to be
empty.
● Note time and speed.
● Measure and note the width of the spreading pattern.
