Quick Reference Card

Use great caution while working around the spreader. Contact with spinners and other moving parts is very dangerous. Do not adjust while machinery is moving, wear eye protection and avoid discharge from spinners. Do not ride on moving spreader.

NOTE: Spinner assembly has NOT been adjusted at the factory. Before spreading material, spread pattern tests must be conducted to properly adjust the spread pattern. A Spread Pattern Test Kit is available for this purpose. THE MANUFACTURER OF THIS SPREADER WILL NOT BE LIABLE FOR MISAPPLIED MATERIAL DUE TO AN IMPROPERLY ADJUSTED SPREADER.

A quick reference card is provided with your machine for testing spread pattern, and adjusting spreader to achieve proper pattern. This card is only for quick reference. Refer to this manual for detailed information.

It is recommended that spread pattern tests be conducted prior to each spreading season, after any spreader maintenance, and periodically during the spreading season. Spread pattern tests must be performed for each product and application rate.

    Spread pattern is affected by many factors. Among the more significant of these are:

  1. Spinner speed.
  2. Material density
  3. Material granule size.
  4. Material flow characteristics.
  5. Rate of delivery of material.
  6. Point of delivery of material on spinner discs.
  7. Balance between deliveries to both spinner discs.
  8. Angle of the distributor fins on the spinner discs.
  9. Cleanliness of the spinner fins and discs.
  10. Level of spreader.
  11. Wind and humidity.
  12. Spacing of swaths.
  13. Wear on spinner fins.

Since many of these factors will vary for each job, trial and experience must be used to determine the adjustments which must be made to obtain the spread width and spread pattern desired. The following instructions are given to cover the adjustments available and the effect that each will have on the spread pattern.
