Raising Openers for Transport
Opener sub-frame is on a dedicated hydraulic circuit.
The openers raise and lower as a group, controlled from
a tractor cab lever.
The following instructions presume that the openers are
lowered, and need to be raised for transport.
Opener Pivot Stop
Refer to Figure 7
1.
Hitch the drill to a suitable tractor. See “Hitching” on
page 14.
2.
If markers are installed, verify that markers are
folded and secured with transport pins. See “Secure
Markers” on page 18. If not, secure them during lift
operations to secure pivot stop for transport.
Marker Pinch/Crush/Sharp Object Hazards:
Secure markers before setting pivot pin. Moving markers can
pinch at mounts crush under arms. Marker disks are sharp.
If not secured by transport pins, markers will fold and unfold
during lift and lower operations.
3.
Retract the opener lift cylinder to fully raise the
openers. Put the tractor circuit control in Neutral to
hold cylinder position.
4.
Note which lettered (A-E) down-pressure pin hole
was previously in use. This is likely to be the same
hole used when the drill next plants.
5.
Remove the pin from the down-pressure adjustment
hole.
Negative Tongue Weight Hazard:
Raising openers on an unhitched drill causes the drill tongue
to rise suddenly, which could cause serious injury or death. Be
certain that drill is hitched securely to your tractor drawbar
and the safety chain is securely attached to tractor before
raising openers.
Refer to Figure 8

Loss of Control Hazard:
Failure of the hydraulic cylinder during transport causes the
openers to drop suddenly, which could lead to serious road
accidents, injury or death. To prevent an accident, always
install the pivot
-stop pin in the transport-lock position before
transporting the drill.
