•
Set header float as light as possible without causing excessive bouncing to prevent knife component breakage,
soil scooping, or soil build-up at the cutterbar in wet conditions.
•
To avoid excessive bouncing and leaving a ragged cut, use a slower ground speed with a light float setting, if
necessary.
•
When cutting off the ground, use the stabilizer wheels in conjunction with header float to minimize bouncing at
the header ends and to control cut height. Refer to
NOTE:
If adequate header float cannot be achieved using all of the available adjustments, an optional heavy-duty spring is
available. See your MacDon Dealer or refer to the parts catalog for ordering information.
To check and adjust header float, follow these steps:
1. Level the header and float module. If the header and
float module are not level, perform the following checks
before adjusting the float:
IMPORTANT:
Do NOT use the float module springs to level the
header.
•
Park the combine on a level surface.
•
Check that the combine feeder house is level. Refer
to your combine operator's manual for instructions.
•
Check that the top of the float module is level with
the combine axle.
•
Ensure the combine tires are inflated equally.
2. Adjust header so that the cutterbar is 150–254 mm
(6–10 in.) off the ground.
3. Extend the header angle hydraulic cylinder to between
B and C on indicator (A).
4. Adjust the reel fore-aft position to between 5 and 6 on
the position indicator decal (A) located on the reel
right arm.
5. Lower the reel fully.
6. Shut down the combine, and remove the key from the
ignition.
