Slide Ruler Calibration
(English
System)
Refer to Figure 8-3:
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 lbs/acre is different than what is found in
the “English Spreader Chart” on page 41. 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 29 1/2".
1. Make sure “ft” marking is in the upper right corner of
the inner slide is showing when Slide Ruler is
oriented as shown with English System facing up.
2. Locate on the Slide Ruler effective spread width in
feet.
Example:
Say 40 feet is the effective spread width in the test
run. Locate 40 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 English System facing up
and the inner slide is pulled part-way out to the right,
you should be able to read
ft
in the upper right
corner of the inner slide. If not, pull inner slid out and
reinsert with
ft
marking in the upper right corner.
3. Determine amount of product (lbs/acre) to be
distributed and adjust Slide Ruler until that amount is
aligned with the effective spread width.
Example:
Say 110 lbs/acre is the distribution rate. Adjust inner
slide until 110 lbs/acre is aligned with 40 feet.
4. Locate on the Slide Ruler tractor travel speed in mph
(miles per hour). Read and record discharge rate
given below travel speed in lbs/min.
Example:
Say the tractor will travel 4 mph. Locate 4 mph on the
Slide Ruler and read the given 35 lbs/min under the
travel speed.
Refer to
English Spreader Chart on page 41:
5. Locate lbs/min for the particular product to be spread
in the “English Spreader Chart” on page 41.
Example:
Say product is Prills at 35 lbs/min Find for Prills that
35 lbs/min requires the regulation bar be set a 18.
Refer to Figure 8-2 on page 39:
6. Set adjusting nut to 18.
Example:
Adjust regulation adjusting nut until front edge of nut
is even with the number 18 on the regulation bar.
