B. Determine a course length by dividing 93 m
(1,000 ft
2
) by the effective spread width.
Note: For example, if the effective width is 1.8
meters (6 feet), then the calibration course length
equals 51 m (167 ft).

C. The calibration course is 1.8 m (6 ft) by 51m (167

D. 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.
3. Set the appropriate drop-rate cam setting; refer to the
Spreading Charts (page 29)
4. Add material to the hopper (for example, add 11.3 kg
(25 lb) add of material).
5. Drive the spreader over the calibration course while
applying the material.
6. Empty the remaining material of the hopper into a
clean bucket; refer to
7. Weigh the bucket containing the material and record
the weight. Pour the contents back into the hopper
and then weigh the empty bucket. Subtract these
two amounts to determine the amount of material
remaining in the hopper—for example, 9 kg (20 lb) of
material is remained in the hopper after applying the
material to the test course.
8. Subtract the amount remaining in the hopper (step 7)
from the amount originally added (step 4); the result is
the amount applied to the course.
Amount Applied
11.3 kg (25 lb) – 9 kg (20 lb) = 2.3 kg (5 lb)
For this example, 2.3 kg (5 lb) of material was applied
to the 93 m

9. If necessary, adjust the drop-rate cam to achieve the
recommended application rate. Once the correct
application rate is achieved, repeat this procedure an
additional time to verify your results.
Important: Designate a new calibration course
each time, so the turf is not damaged by excessive
application of material.

5. Remove the cover from the hopper, add the material
to be spread, and install the cover onto the hopper
(Figure

Note: Do not overload the hopper; the maximum
weight capacity of the hopper is 79 kg (175 lb).
Note: One extra bag of granular product may be
placed on top of the sprayer tank; however, this is not
recommended if the operator is heavy.
