Adjust Application Depth
Depth of material placement can vary
depending on the type of application. Check
with the fertilizer or chemical manufacturer
for information regarding application depth.
Set toolbar, coulter/disc, or nozzle to
required depth.
Once the desired field location of the
application is reached, the center section
and main wing kick may be lowered by
pushing SCV I forward.
Even after coulters are in ground, SCV I must
be constantly engaged to provide oil supply
to and drain from down pressure circuit.
Failure to keep SCV I engaged and constant
supply of oil flow to the down pressure
system may result in coulters riding out of the
ground and could result in structural failure of
the toolbar and/or hydraulic cylinder
components.
IMPORTANT: DO NOT exceed SCV I
flow setting of 90%.
A. Spacer
Install spacers (A) on the toolbar lift cylinders’
ram to give the required machine depth. The
toolbar can then be fully lowered and always
return to the same depth.
Adjust Gauge Wheels
A. Pin
Each inner-wing and outer-wing is equipped
with a gauge wheel that helps to maintain the
application depth. Lower the gauge wheels if
soil conditions are soft and raise if they are
hard to obtain the same application depth.
1. Remove pin (A) and adjust gauge
wheel height as desired.
2. Install pin and lock pin.
3. Repeat for the other side.
