Raising Openers for Transport
The 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.
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.
Opener Pivot Stop
1. Hitch the drill to a suitable tractor. See “Hitching” on
page 13.
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.
2. Retract the opener lift cylinder to fully raise the
openers. Put the tractor circuit control in Neutral to
hold cylinder position.
Refer to Figure 8

hole.

position .

wheels, the hitch tongue can be elevated to
vertical to reduce the length of the drill.
