Rate Charts - Continued
Rate Chart Use
The rate chart applies to all spacings listed below.
The spacing sprocket must be matched to the seeding
tool trip spacing see
“Spacing Sprocket” .
The charts should only be used as a guide. Specific
rates can be achieved by using the rate check method
as outlined under
“Rate Calibration” .
To determine a seed/fertilizer rate from the chart:
• Go to the desired rate along the line marked
“Standard” of a specific graph. (i.e. 95 lbs/acre of
wheat)
• Go straight up from that point to where that line is
intersected by the graph. This will give the sprocket
size required to give the particular rate chosen.
• At this intersection go straight across to the vertical
line of the graph. This will give the sprocket size
required to give the particular rate chosen. (i.e. 95
lbs/acre of wheat requires a 29 tooth sprocket)
• Change the Quick Change Sprocket see “Metering
Rate Adjustment” .
• Perform a rate check to confirm the seed rate see “Rate
Calibration” .
• Repeat the above
procedure for the
other tank.
• For very low or
very high rates,
see next page
“ E x t r a L o w
Rates”
and “Extra
High Rates” .
Note: The rate charts should only be used as a
guide. Variation in seed size, density, shape,
tire pressure and wheel sinkage are all
factors that can influence the seed rate.
