Measure AND RECORD the amount of time it takes to
spread 1,000 ft
2
(93 m
2
) of area. NOTE: The machine is
designed to operate at a full throttle engine speed of 3450
RPM while in NEUTRAL. Check engine speed with the
tachometer and adjust to 3450 RPM if needed (see
Adjusting Engine speed to 3450 RPM in the Service
Manual section). Keeping the engine speed constant,
helps insure that the application rate remains constant.
Create a test course based on the effective Spread Width
from the table above. EXAMPLE:
Triumph comes set from the factory to an effective
spread and spray width of 7 FEET, which can be
accomplished by making 7 FOOT center-to-center
parallel passes overlapping approximately 50
PERCENT of the last pass. Measure a distance
equal to the of 143 FEET (44 meters) over turf. This will
provide a spread area of approximately 1,000 ft
2
(93
m
2
). The effective material spread width for many
products is 7 FEET; therefore, 7 x 143 = 1,001 ft
2
(93
m
2
). NOTE: If your calibr ated effective spread width
is 8 feet, you will use 8 x 125 = 1000 ft
2
as the basis for
making the following calculations.
With the machine traveling in HIGH GEAR at full
throttle, use a stopwatch or wristwatch to measure AND
RECORD the time required to travel the 143-FOOT
(44 meter) turf course. The normal time is approximately
20 seconds ± 1 seconds.
With the machine operating in LOW GEAR at full
throttle, RECORD THE TIME required to cover the 143-
FOOT (44 meter) turf course. The normal time is
approximately 28 SECONDS ± 1 SECOND.
Measure and adjust the output of the spreader to deliver 3
POUNDS (1.36 Kg.) per 1,000 ft
2
(93 m
2
).
Place a ground cloth on a paved area.
Place enough product in the Hopper to conduct several
delivery rate checks.
Drape a drop cloth over the Hopper to contain and deposit
the product spread onto the Ground cloth.
With the machine in NEUTRAL, accelerate the engine to full
speed and open the Hopper for the actual time you
recorded for the HIGH GEAR time test above (from our
example we will use 20 SECONDS).
Move machine off Ground cloth and weigh the product
collected.
If the product collected weighs less that 3 POUNDS (1.36
Kg), reposition the Rate Adjustment Knob to a higher setting
on the Rate Scale to increase the opening in the Hopper.
Repeat the collection test and readjust as required.
Once the proper rate has been established RECORD the
Rate Adjustment Knob and Calibration Gage settings for
future use.
Repeat the procedure for the LOW GEAR time (for our
example we will use 28 SECONDS).
