Operation
Implement Leveling
When fully raised, the opener tool bars of all three
sections should be at the same height. This
measurement is most accurately made on a flat
paved surface.
Implement operating height/level is controlled at
several points:
Center frame tool bar height is controlled by
spacers on the lift cylinder rods.
Front-to-back level is automatic. User adjustment
of the lift link is not recommended. In the event of
dismount during maintenance or repair, factory
link length is 2020 mm center-to-center.
Wing tip tool bar height is primarily controlled by
gauge wheel cylinders.
Wing tilt is controlled by wing weight transfer. The
weight transfer adjustment necessary varies with
field conditions.
Wing Leveling Eye Bolts
Wing tip tool bar height is normally set by the wing lift
cylinders. These are rephasing cylinders operating
as slaves to the center section (master) lift cylinders.
The master cylinder lowering limit is set by spacers.
If wing tip tool bar height is not the same as the
center section tool bar height, make these checks
before considering any adjustment to the eye bolts:
1. Make sure the lift system is charged and bled. If
there is any air in the system, the wing heights
may not track the center height (or each other).
2. Make sure the lift system is rephased. If the wing
cylinders are not tracking the center cylinders,
rephase the cylinders.
3. Check tire inflation.
4. Make sure weight transfer is properly set for
conditions. If the wing gauge wheels are off the
ground (or nearly so), there may be too little
weight transfer. If the center section is running
high, and the wing ends are low, there may be
too much transfer.
5. Check the current eye bolt setting. Before any
adjustment, make sure that it was at the
factory-recommended setting. The distance (A)
from the base of the cylinder lug tube (1) to the
flat top of the eye bolt lug (2) is factory-set to
57 mm
.
To adjust the gauge wheel height:
6. Unfold the implement on flat ground. Fully raise
the implement.
7. Loosen the jam nut (3).
8. Set the gauge wheel height with the adjust nut
(4). Adjust until the opener tool bar height at the
wing tip is the same as center opener tool bar
height.
9. Tighten the jam nut.
If the left and right wing cylinders are not
operating identically, the problem is
hydraulic, and not a mechanical
adjustment.
Frame-Mounted Coulters
Frame-mounted coulters are used in-row and
prepare the soil directly ahead of the seed furrow.
The factory suggested default setting with new
coulter blades at 3.8 cm opener (planting) depth (A),
is a coulter depth (B) of 5.1 cm, or 13 mm below
opener depth.
