Fertilizer Feed Shaft Speed
Speed is determined by sprocket combinations.
There are three (3) different speeds available in
the fertilizer gear box along with six (6) speeds on
the drive ends of the drill. See pages 60 and 61.
Use a slow speed combination whenever
possible for maximum efficiency and to
minimize wear.
Use a fast speed combination for drilling larger
quantities.
Fertilizer Drive Settings
The different types of fertilizer you apply will all
have different delivery rates. Samples need to be
caught to determine your particular material's
delivery rate per rotor revolution in ounces per
revolution.
To determine your rate, see page 61 and use
example with your delivered ounces per 10
revolutions to find your rate column.
Determine how many pounds per acre you wish to
apply and then find it on the chart page. Move
over to the sprockets A through F on the same
line to find the sprockets you need to apply the
poundage you have selected. Locations of these
sprockets can be found on page 60.
NOTE: When you are not distributing fertilizer,
remove the chain between the 14 tooth
sprocket A and the 40 tooth sprocket B.
Cleaning Fertilizer Box

doors B as shown.

IMPORTANT:
If drill is not used for several days, empty and
