Locking Pins
Refer to Figure 19
Each wing has two removable pins, stored in the parking
stand
when not in use:
• Wing Lock Pin
Used to connect the wing tool bar to the center section
tool bar during planting operations, and 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)
• Wing Flex Lock Pin
Required to stabilize pivot during folding and
unfolding. Used during planting to prevent wing flex.
The following table summarizes pin use.
The
INNER pins must be IN
and the
OUTER pins must be OUT
during folding and unfolding,
or machine damage will result.
