Spread Pattern
Spinners
NOTICE!
Spinner discs and
fi
ns must be kept clean and polished. Even a small build-up on a spinner
fi
n can signi
fi
cantly affect the spread pattern. Rusty, rough, bent or worn
fi
ns will produce
poor spread patterns.
In general, critical spinner speed will fall somewhere between 600 and 900 RPM. Spinner speed is adjusted
by changing the settings in the controller. Proper spinner speed adjustment is critical in obtaining optimal
spread patterns. The best spinner speed to use will depend entirely on the material being spread, and
must be determined by testing.
Spreader Preparation
The spreader to be tested must be in good mechanical condition and properly adjusted. Refer to operator’s
manual for details .
All damaged and worn parts must be replaced. Spinner discs and
fi
ns must be free of any material build-
up, rust or paint.
Fill the hopper with the material to be spread. Run the material out to the end of the conveyor.
Set the feedgate and the in-cab controller to deliver the required rate per acre. Make sure the feedgate
is level and the indicator re
fl
ects the actual gate opening measured by standing a tape measure vertically
in the material.
NOTE:
Do not match slope of endgate when making this measurement. Measurement must be
perpendicular to conveyor.
Adjust the spinner assembly by turning the crank or, if an actuator is installed, change the setting in the
controller. To begin testing, position the spinner according to the chart below.
