6.4.2 HEADER FLOTATION
Float is intended for cutting crops that require
the cutterbar to be in contact with the ground.
Optimum float is for the cutterbar to maintain
contact with the ground with minimum bouncing
and scooping or pushing soil.
The machine will perform best with minimum
extra weight on the header.
IMPORTANT
To avoid frequent breakage of sickle
components, scooping soil, or soil build-up
at cutterbar in wet conditions, header float
should be set as light as possible without
causing excessive bouncing. When float
setting is light, it may be necessary to use
a slower ground speed to avoid excessive
bouncing and leaving a ragged cut.
IMPORTANT
The stabilizer wheels are designed to
minimiz
e
bouncing at the header ends and
not “float” the header. Refer to the D50
and D60 Harvest Headers for Self-
Propelled Windrowers Operator’s Manual
(Form #169441) for adjustment details.
6.4.2.1 Float Operating Guidelines
When working with the cutterbar on the ground;
•
Set center link to mid-range position (05.0
on CDM). Refer to Section 6.4.5 Header
Angle.
•
In rocky fields, adjust skid shoes down to
raise guards when operating at flattest
header angle to minimize scooping rocks.
•
Adjust header height or adjust header angle
to minimize pushing soil.
6.4.2.2 Float Adjustment
The M Series windrowers are equipped with
primary (coarse) and secondary (fine)
adjustment systems. The primary or coarse
adjustment uses drawbolts to change the
tension on the springs in the lift linkages. The
secondary or fine adjustment uses hydraulic
cylinders to change the spring tension.
a. Check header float as follows:
CAUTION
Check to be sure all bystanders have cleared
the area.
1. Start the engine.
2. Using HEADER TILT SWITCHES, set
center link to mid-range position (05.0 on
CDM) (A).
3. Using HEADER DOWN switch, lower
header fully with lift cylinders fully retracted.
4. Set left and right float fine adjustments on
the CDM to approximately 5.0 as follows:
i) Using float selector switch (B), push
+
to
increase float, or
–
to decrease float on
left side of header. CDM display (A) will
indicate selected float for left side, for
example (5.0 L FLOAT R XX.X).
ii) Repeat for right side float with switch
(C). Display will indicate float for both
sides, for example (5.0 L FLOAT R 5.0).
5. Shut down engine and remove key.
