Slide Ruler Calibration
(Metric System)
Refer to Figure 8-6:
The quantity of product being spread is controlled by the
regulation bar, effective spread width and ground speed.
It is necessary to use the Slide Ruler when effective
spread width or kgs/hectare is different than what is found
in the “Metric Spreader Chart” . The Slide Ruler is
developed to calibrate discharge rates under the
following conditions:
•
Tractor power take-off speed is 540 rpm.
•
The standard pendulum spout is attached.
•
The spout is parallel to ground surface.
•
The distance between the spout discharge end and
ground is 75 cm.
1. Make sure “m” marking is in the upper right corner of
the inner slide is showing when Slide Ruler is
oriented as shown with Metric System facing up.
2. Locate on the Slide Ruler effective spread width in
meters.
Example: Say 12 meters is the effective spread width
in the test run. Locate 12 on the Slide Ruler.
IMPORTANT:
Before using the Slide Ruler, make
sure the inner slide is oriented correctly. When the
Slide Ruler is held with Metric System facing up and
the inner slide is pulled part-way out to the right, you
should be able to read
m
in the upper right corner of
the inner slide. If not, pull inner slid out and reinsert
with
m
marking in the upper right corner.
3. Determine amount of product (kg/hectare) to be
distributed and adjust Slide Ruler until that amount is
aligned with the effective spread width.
Example:
Say 128 kg/ha is the distribution rate. Adjust inner
slide until 128 lbs/acre is aligned with 12 meters.
4. Locate on the Slide Ruler tractor travel speed in
km/h (kilometers per hour). Read and record
discharge rate given below travel speed in kg/min.
Example:
Say the tractor will travel 10 km/h. Locate 10 km/h on
the Slide Ruler and read the given 25 kg/min. under
the travel speed.
Refer to
Metric Spreader Chart on page 45:
5. Locate 25 kg/min for the particular product to be
spread in the “Metric Spreader Chart” .
Example:
Say product is Granular Fertilizer Fine at 25 kg/min.
Find for Granular Fertilizer Fine that 25 kg/min
requires that the regulation bar be set at 33.
Refer to Figure 8-5 on page 43:
6. Set adjusting nut to 33.
Example:
Adjust regulation adjusting nut until front edge of nut
is even with the number 33 on the bar.

1. Verify inner slide is oriented with “m” facing up.
4. Locate tractor traveling speed in km/h.
5. Read & record kg/min.
6. Locate kg/min for the particular product being spread in the “Metric Spreader Chart” on page 45.
7. Read and record regulation bar setting provided in "Metric Spreader Chart".
