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).
Transport Lift is normally used prior to folding and during
rate calibrations. Opener Lift, and not Transport Lift, is
used for headland turns in field operations.
Swing-up channels are used to lock the lift cylinders in
the raised (extended) configuration, preventing settling
during transport, parking, calibrations, servicing and
storage.
Refer to Figure 21
Note: Wings flex down before gauge wheels are lifted off
the ground during transport lift.
Transport Lift
1. Raise the openers. See “Raising and Lowering
Openers” on page 23.
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 41.
3. Supply oil to the base (extend) ends of the Transport
Lift cylinders.
