Operation
7.
Place the rate dial and linkage to a setting lower
than the maximum open position.
8.
Allow the spreader to completely dry before the
next use.
9.
Lightly oil spreader components to help reduce
corrosion.
Spreader Calibration
The spreader should be calibrated each time a new
material is used. The spread width ranges from 3-25
ft (0.9-7.6 m) and depends on the material particle
size, volume/density, and rate of travel.
Refer to the spreading charts along with
Determining the Distribution Pattern,
Determining the Effective Spreading Width,
and
Calculating the Application Rate
sections to
calibrate the machine.
Determining the Distribution Pattern
Important:
The tines are rotating when the
tines are lowered and the motion control lever
is moved out of the neutral position. Make sure
the tines are raised all the way up before starting
this procedure.
Operator supplied equipment:
15 shallow
collection pans and 15 graduated measuring cylinders
The most accurate method to measure the
distribution is to use shallow collection pans and
graduated measuring cylinders. In the example below,
15 shallow collection pans approximately 30 cm (12
inches) wide, 91 cm (36 inches) long, and 5 cm (2
inches) tall are used.
1.
Make sure to allow ample driving distance before
setting up the pans to ensure the machine is
traveling at the desired spreading speed before
reaching the pans.
2.
Place one pan in the center of the drive path.
Arrange the next two pans, one on each side,
far enough apart to allow ample room for the
spreader drive tires to pass over the center pan.
3.
Place the remaining pans in a straight line as
shown in Figure 18 or Figure 19.
•
For larger granule materials:
Space six additional pans, on each side, 12
inches (30 cm) apart (see Figure 19).

Place six additional pans, on each side, with
no gap in between each pan (Figure 19).
