3.9.1 Product meter adjustment

The product meters send the seed or fertilizer
from the product bins to the air stream through a
fluted roller. The amount of the roller being used
determines the rate at which products are applied.
There are two moveable components in the meter
that determine the rate setting:
• Flow plate
• Meter shut off slide
The flow plate (1) controls how much of the meter
roller will be used. The meter shut off slide (2)
opens to the stop on the pointer for any rate
setting. When making large rate reductions, close

the slide and empty the meter to let the flow plate
move to the lower setting. After the flow plate is
moved, open the meter shut off slide until contact
is made with the stop on the pointer.
The primary setting is a flow plate adjusted by a
rod connected to a pointer. When a rate setting is
selected, the pointer is put at the number shown
on the rate decal. A lock bolt on the pointer rod
holds the setting.
The second part of the adjustment is the meter
shut off slide. For any rate setting the correct
location for meter shut off slide is against the stop
on the pointer. This opens the bottom of the tank
compartment the correct amount for the rate
setting. A 12.5 mm (0.5 inch) drive ratchet is
supplied in the toolbox for adjusting the meter
shut off slide.
Any time a new rate is set, calibrate the meter. A
scale and a catch bag are supplied in the tool box
for use during the calibration procedure.
Once a rate setting is determined from the rate
charts and the meter is set to the correct setting,
do the calibration procedures.
When using both tanks for one product, determine
the rate for each meter by splitting the desired rate
by the ratio of the tanks (60/40). This will result in
both tanks being empty at the same time.
Examples:
To seed 135 kg per hectare of wheat using both
meters, split the desired rate to the ratio of the
size of the tanks. For a 60/40 split, set one meter
to 81 kg (135 kg x .60) and the other meter to 54
kg (135 kg x .40)
To seed 120 lbs per acre of wheat using both
meters, split the desired rate to the ratio of the
size of the tanks. For a 60/40 split, set one meter
