6.4.2.3 Leveling
The windrower linkages are factory set to
provide the proper level for the header and
should not normally require adjustment. If the
header is not level, perform the following checks
prior to adjusting the leveling linkages. The float
springs are not used to level the header.
a. Raise header to full height and keep HEADER
UP switch depressed to ensure lift cylinders are
phased.
b. Check drive wheel tire pressures.
c. Check and set float adjustment. Refer to
previous sections.
d. If header is not level after the above checks,
adjust as follows:
1. Place float pins in locked out location (A).
2. Park windrower on level ground.
3. Set header approximately 6 inches (150
mm) off ground and check that member (B)
is on link (C) as shown. Note high and low
end of header.
4. Place wooden blocks under header
cutterbar and legs.
5. Lower header onto blocks so that members
(B) lift off links (C). Stop engine.
DANGER
Stop engine and remove key from ignition
before leaving operator's seat for any
reason. A child or even a pet could engage
an idling machine.
6. On high side, remove nut, washer and bolt
(D) that attaches shims (E) to link.
7. Remove one or both shims (E) and reinstall
the hardware (D).
CAUTION
Check to be sure all bystanders have cleared
the area.
