Quick Tips
Note: Read the Operator’s Manual for detailed
operating and adjustment instructions.
Shank Trip Force
Shank trip force (lbs) is calculated by dividing the display
pressure by 1.5 (ex. 750 psi display pressure = 500 lbs
shank trip force). Shank trip out pressure is generally
set at the minimum pressure that keeps the shanks
solid in the vertical position and prevents them from
repeatedly “tripping out”, while still providing adequate
packing. Maximum recommended shank trip out
pressure is 1200 psi.
Packing Force
Packing force is proportional to shank trip out force
and is roughly 1/3 of the shank trip force (ex. 500 lbs
shank trip force would give approximately 167 lbs of
packing force).
Hydraulic System
The Quantum Air Drill uses an active hydraulic system
meaning that approximately 3-4 GPM will be consumed
by the system during operation. A reducing/relieving
valve (S2) sets the pressure value and is controlled
from the cab. Operating pressure range is normally
anywhere from 500 to 1500 psi depending on soil
conditions, opener selection and ground speed. Opener
pressure can be reduced on the go for soft spots or tilled
areas in the eld or increased for hard packed areas.
Float position (equal pressure on both sides of opener
cylinder) is also possible using the Topcon system and
can be effective at walking the drill through low spots.
Lifting and Lowering the Openers
Openers will travel all the way up or all the way to
working position based on the controller selection; there
is no middle operating position. Ensure the openers are
fully lifted with the transport ball valve locked and the
tractor hydraulics off for road transport.
