Spread Pattern

Spinners

Spinner discs and fins must be kept clean and polished. Even a small build-up on a spinner
NOTICE!
fin can significantly affect the spread pattern. Rusty, rough, bent or worn fins 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 fins 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 reflects 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 following chart�
