6.4.3 LEVELLING
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. Check windrower tire pressures.
b. Place float pins in locked out location (A).
c. Level header as follows:
1. Park windrower on level ground.
2. Raise header fully, and hold momentarily to
allow lift cylinders to re-phase.
3. Set header approximately 6 inches (150 mm)
off ground, and check that member (B) is
against link (C). Note high and low end of
header.
4. Place wooden blocks under header cutterbar
and legs, and 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.
5. On high side, remove nut, washer, and bolt
(D) that attaches shims (E) to link.
6. Remove one or both shims (E), and reinstall
the hardware (D).
d. Start engine, and raise header slightly. Check
level of header.
e. If additional levelling is required, install the
removed shim on the opposite linkage.
f. Once header is level, return float pins to their
engaged position (F).
NOTE
If required, additional shims are available
from your MacDon Dealer
