Planter Leveling
Center Section Leveling
Refer to Figure 170 (which depicts the planter on
pavement - perform this adjustment in the field)
1. Put planter in field position by lowering and pulling
forward.
Leveling Mis-adjustment Risk:
Planter must be fully lowered to field position and hitch height
must be set before making side-to-side adjustments.
2. Measure the elevation of both left and right sides of
the planter, near the wing pivot location. If they are
not the same, adjust the tractor 3-point arm linkage
to equalize, while keeping center height at desired
value (nominally 26 inch / 66 cm).
Wing Leveling
Wing leveling check/adjustment is required prior to first
use of the planter, and periodically thereafter, such as
when using a different tractor, or when the tractor set-up
has been modified for use with another implement.
Before performing this operation:
•
Planter must be hitched and all connections made.
•
See “ Hitching Tractor to Planter ” on page 15.
•
Planter must be unfolded on firm level ground.
•
See “ Unfolding the Planter ” on page 36.
•
Planter must be lowered.
•
Center section must be leveled.
•
See “ Frame Height and Leveling ” on page 22, and
“ Center Section Leveling ” on page 168.
•
Wing Flex Lock pin must be installed. Wing (down)
lock pin must be removed and wing flex lock pins
must be removed and in storage ( Refer to Figure 37
on page 37 ).
Refer to Figure 171 and Figure 172 (which depict the
planter on pavement - perform this adjustment in the
field)
1. Measure from the bottom of the wing tool bar to the
ground at the outer end of each wing.
2. Compare to the measurement at the outer end of the
center tool bar, at the wing pivot location. All
measurements should be identical, and nominally 26
in.
3. If measurements do not match, loosen upper wing
link arm lock nut , and adjust link length.
4. If adjustments are needed on either side, re-check
the other side after each adjustment, and readjust it
as needed.
5. Once level, tighten the wing link arm lock nut .
