WARNING
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.
It is highly recommended to perform a Catch Test, Crush Strength Test and SGN Scale Test prior to each season,
before using a new product, or if a significant visible change has occurred with a product. Testing will define
granular characteristics and help determine proper spinner settings for optimal product spread.
Conduct a G4 Spread Pattern test to check settings based on test results. Refer to
G4 Spreader Installation
Instructions
and
G4 Spread Pattern Manual
for installation and adjustment instructions.
CRUSHING STRENGTH
Crushing strength is the minimum pressure needed to crush individual particles.
Testing and knowing the crushing strength of a particular product will help determine maximum spinner RPM. For
example: Any granule with less than three (<3) crush strength should not be broadcast with spinner speeds over
700RPM. Verify granules are not pulverized before increasing spinner speed. Refer to
Product Setup Guidelines
for additional spinner speed settings with different crush strength.
SGN
SGN (Size Grade Number) is the measurement of granule size in millimeters multiplied by 100. A product’s SGN
will affect spread width.
Materials with poor uniformity (a significant percentage in 3 or more colums of scale device) may be difficult
to spread accurately. Spread Pattern testing should ALWAYS be performed on any new or different material to
determine actual spread width.
