Unfold: Summary of Steps
Follow the detailed instructions in step 1 through step 14
until this is a familiar operation.
❑ Check markers, auger and ladder stowed (below).
❑ Set mainframe transport locks to FIELD (below).
❑ Release transport hook (page 36).
❑ Set tractor for unfold (page 36).
❑ Unfold wings (page 37).
❑ Check openers raised (page 41).
❑ Set outer wing locks to FIELD (page 39).
❑ Tilt down wings (page 39).
Unfold: Check Drill Configuration
Wings can collide with a deployed auger or ladder.
1. Make sure:
ladder (page 54),
auger (page 64) and
markers (page 73)
are secured in their transport positions before
unfolding.
2. Move to level ground.
Sudden Implement Movement Risk:
Always have hydraulic levers in Neutral when operating CFM
switches.
3. Set/check that CFM switches (see page 33) are all
Off and hydraulic circuits are all in Neutral.
Shut off tractor.
Unfold: Two Mainframe Locks: ROAD to
FIELD
Refer to Figure 21
4.
On both sides of the mainframe, pull the wire handle
outward and move to rear slot. This allows hooks
(not shown) to move forward and enables lowering of
the centre section openers (after unfold). If the
openers are not fully raised, the hooks may not move
immediately. Tension in the wire loop handle is
expected in that case.
Note: Lowering the openers is not part of the unfold
operation, but these locks are easier to reach
before the wings are unfolded.
