Planting recommendations
To get the best planting results, follow these
recommendations:
•
Plant at 5 mph
•
Add 1 teaspoon of graphite to each seed hopper.
•
Maintain tire pressure in the gauge tires.
•
Replace worn meter parts.
Adjusting Granular Chemical Rates
The optional chemical applicators are adjusted by
varying the opening on the chemical meter housing. The
field check is very important because temperature, hu-
midity, speed, ground conditions, flow ability of
chemicals, and obstructions affect the application rate.
!
WARNING!
Agricultural chemicals can be dangerous if not selected and
handled with care. Always read and follow directions sup-
plied by the chemical manufacturer.
To adjust the chemical rate do as follows:
1. Select a setting from the "Granular Chemical Rate
Chart" on pages 16 through 24, as a starting point.
2. Slide the handle on the meter to the setting,
see Figure 4-2 and Granular Chemical Rate Chart
on pages 23 and 24.
3. If the meter has a knob, turn until the display shows
the appropriate number, see Figure 4-2 and Granu-
lar Chemical Rate Chart on pages 16 through 20.
4. Fill the hoppers with chemical.
5. Attach a plastic bag to each chemical
diffuser.
6. Drive 1320’ at a normal planting speed.
7. Weigh the contents of the bag in ounces.
8. Multiply ounces by.83 to determine the pounds
per acre.
9. If required, adjust the meter setting and repeat steps
4 through 7 until the desired rate is reached.
