The slide rule
The slide rule that has been supplied with your spreader is used for
determining the flowrate in lbs per minute (step 1-4).
You use it for:
•
finding the setting of the regulating rod on the spreading chart
decal (steps 5 and 6).
•
and for performing a calibration test.
(step 7 is for the disc spreaders)
Metric and Imperial
On the front of the slide rule are metric units and on the back imperial
units.
The slide rule consists of three parts:
•
Transparent ruler with hairline; can slide along outer case.
•
Outer case with 6 steps to determine the setting.
•
Sliding ruler with the values lbs/acre and lbs/min on the imperial
side; can slide to the left or right.
