center graduated cylinder.
3. Go to the two corresponding pans. Starting from
the outer edge, measure the distance between
left pan, across the center pan, to the outer edge
of the right pan, and record the measurement.

Preparing the Calibration Course for
Calculating the Application Rate
1. Determine a course length by dividing 93 m
(1,000 ft 2 ) by the effective spread width that
you determined in
Spreading Width (page
length formula. Record the course length
here:
Calibration Course Length Formula
93 m
/ Effective width
Formula measurement
Example 93 m
/ 1.8 m (6 ft)
Note:
In this example the effective width
measures 1.8 m (6 ft).
2. Measure and visibly mark the course length.
Ensure that you allow enough distance before
the starting marker so that the spreader moving
forward at full speed when crossing the first
mark of the course.
Calculating the Application Rate
1. Determine the area and amount of material that
you are applying to the job site and record those
amounts in the area and materials worksheet.
Record the job site area here:
Record the amount of job site material here:
2. Initially, use the recommended application rate
indicated in the Spreading Charts (page 31)
section or use the rate recommended listed on
the product manufacturer's label as a guide to
help determine the amount of material that you
would spread over a 93 m
Note:
In this example the calibration course is
1.8 m (6 ft) by 51m (167 ft).
3. Set the appropriate drop-rate cam setting; refer
to the Spreading Charts (page 31)
point.
4. Add material to the hopper.

Note:
In this example we added 11.3 kg (25

5. Drive the spreader over the calibration course
while applying the material.
6. Empty the remaining material of the hopper into
a clean bucket.
7. Weigh the bucket containing the material and
record the weight. Pour the contents back
into the hopper and then weigh the empty
bucket. Calculate the remaining material weight
using the remaining material weight formula.

Note:
In this example, 9 kg (20 lb) of material
remain in the hopper after applying the material
to the test course.
8. Calculate applies material weigh using
the applied material formula that follows.
Record the applied material weight here:

Note:
This calculation means that at the
selected motor-rotation speed, 2.3 kg (5 lb) of
material was applied to the 93 m
course.
9. If necessary, adjust the drop-rate cam to achieve
the recommended application rate. Once you
achieve the correct application rate, repeat
this procedure an additional time to verify your
results.
Important:
course each time, so that the turf is not
damaged by excessive application of
