Implement Locks
Depending on configuration, there are 2 to 4 sets of locks
requiring attention at various phases of operations:
Refer to Figure 12
1.
Wing Flex Lock Pin (see page 22)
Required to stabilize pivot during folding and
unfolding. Used during planting to prevent wing flex.
2. Wing Lock Pin (see page 22)
Used to keep the wing tool bar at the same height as
the mainframe tool bar. When this pin is installed at
the coupling, the outer wing is either rigid, or can flex
(depending on the planter “flex” configuration).
3. Lift-Assist Lock Channels (Option, page 23)
These channels, stored on the lift-assist weldments,
are installed on the lift cylinder rods to hold the rear
of the planter at raised.
4. Row Lock-Up Pins (Option, page 65)
For converting twin-row to single-row.
Wing pins store in the parking stands when not in use.

The following table summarizes wing pin use.
Machine Damage Risk:
The
INNER pins must be IN
