Raising Drill (Transport Lift)
Transport Lift is on a dedicated hydraulic circuit. The
center main frame raises and lowers independently of
the opener sub-frames (which are raised and lowered by
the Opener Lift circuit).
The Transport Lift circuit also includes a cylinder for the
Transport Hooks, which lifts and restrains the
outer/forward ends of the wing sections when folded.
Transport Lift is normally used only when the drill is
folded. Opener Lift, and not Transport Lift, is used for
headland turns in field operations.
Note: If the drill is unfolded, gauge wheels do not lift off
the ground during Transport Lift. The wing sections
pivot, and the gauge wheels remain on the ground.
As they do not caster, they can drag sideways if
Transport Lift is used before Fold.
Transport Lift
1. Fold the drill (unless this lift is for maintenance or
adjustment). See “Folding” on page 27.
2. If the Two Outlet conversion kit is installed, a selector
valve near the hitch must be operated to switch
between Transport Lift and Opener Lift. See “Lift
Selector Valve Operation” on page 44.
3. Supply oil to the base (extend) ends of the Transport
Lift cylinders.
Refer to Figure 20
4. Leave the circuit extended until mainframe lift is
complete, the transport hooks
have engaged, the
wing ends are lifted off the ground, and the front box
lift cylinder
is fully extended.
Refer to Figure 21
5. Swing the locks up and onto the transport lift
cylinders. They are temporarily held in place with
polymer bumpers. They are firmly held in place when
the cylinder is relaxed in step 7.
