Treatment Rate (Option)
This section covers application of granular dry
treatments using the optional on-row treatment hoppers.
Treatments may include insecticide, herbicide and other
small granular or pelletized materials.
Agricultural Chemical Hazard:
Follow all chemical supplier precautions for handling
treatments. Wear protective equipment prescribed for the
current material, and for all previous materials used since
last thorough hopper clean-out. Read and follow material
label directions. Obtain and retain MSDS
a
information for the
present and recent materials. Many treatments are extremely
hazardous and can cause disabling or fatal injury.
Refer to Figure 13 and Refer to Figure 14 on page 27
Treatment application rate is determined by a
combination of:
• meter dial setting
(which controls the meter gate opening), and
• field speed
(application rate is inversely proportional to field
speed).
The system may be uncoupled at the clutch if no
treatment is being applied.
The treatment meter has an agitator powered by the
seed meter drive, but treatment application rate is
relatively
b
insensitive to agitator rpm.
There are four steps to obtaining the target treatment
weight in kg per hectare (or pounds per acre):
1. Find your target rate, for your planned field speed, in
the charts beginning on page 30.
2. Perform a Gate Calibration (see Operator manual) at
the start of each season, or if one or more rows is
metering at unexpected rates.
3. Perform a Rate Calibration (page 28).
a. MSDS - Material Safety Data Sheet
b. Finer materials with low cohesion may flow when the planter is stopped. Set meters to “00” to prevent material loss.
