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 signifi cant visible change has occurred with a product. Tes ng will defi ne
granular characteris cs and help determine proper spinner se ngs for op mal product spread.
Conduct a G4 Spread Pa ern test to check se ngs based on test results. Refer to
G4 Spreader Installa on
Instruc ons
and
G4 Spread Pa ern Manual
for installa on and adjustment instruc ons.
CRUSHING STRENGTH
Crushing strength is the minimum pressure needed to crush individual par cles.
Tes ng and knowing the crushing strength of a par cular 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
addi onal spinner speed se ngs with diff erent crush strength.
SGN
SGN (Size Grade Number) is the measurement of granule size in millimeters mul plied by 100. A product’s SGN will
aff ect spread width.
Materials with poor uniformity (a signifi cant percentage in 3 or more colums of scale device) may be diffi
cult
to spread accurately. Spread Pa ern tes ng should ALWAYS be performed on any new or diff erent material to
determine actual spread width.
