Spread patterns can also be adjusted by moving the point of delivery toward the outer edge of the
spinner or into the center. Placement of fertilizer near the outer edge of the spinner will increase
the amount of fertilizer deposited behind the spreader. Shifting the point of delivery to the center
of the spinner will increase the amount of material thrown to the sides.
Spinner Blades or Fins
The purpose of the spinner blades is to catch the material deposited
on the spinner and guide it so the fertilizer is thrown off at the
proper angle.
Spinner blades, or fins, are formed in a manner to give an effective
loft and trajectory of material. However, in time, they will wear
and disfigure from the abrasiveness of the materials. Excessive
wear can cause an uneven spread pattern. Worn fins should be
replaced before they affect the spread pattern. They can be
purchased from your nearest dealer or by calling our BBI parts department.
Spinner Speed
Predicting how an increase or decrease in spinner speed will affect the pattern of distribution is
difficult. This adjustment should be made only after other methods of adjustment fail to give a
satisfactory pattern. Increasing spinner speed may increase or decrease the material directly
behind the spreader, depending on the material being spread, the original spinner RPM, and type
of blade setting. Adjustments with spinner speed will be by trial and error and is less predictable
than other means of adjustment.
ACCURATE METERING OF FERTILIZER MATERIALS
Once an adequate spread pattern has been obtained, the spreader should be calibrated to deliver
the desired rate per acre.
Tables for determining the gate setting can be found on the spreader decal on the side of the
hopper. Many times an operator will set the gate according to the rate chart and be disappointed
when he comes up short or has product left over at the end of the field. This discrepancy is
usually caused by the miscalculation of the bulk density or weight per cubic foot. The
guesswork of estimating the weight per cubic foot of a blend can be eliminated with the use of
the weigh scale or weighing 7.5 gallons as previously discussed.
After the spreader has been successfully calibrated and tested, it is ready for use.
Remember to USE EXTREME CAUTION and FOLLOW ALL SAFETY
INSTRUCTIONS while operating this machinery.
