HEADER LEVELLING
NOTE:
Adjust header level before adjusting
header flotation.
To level header:
1. Ensure pins (G) are at the top of slots in bars
(F) on both sides.
2. Loosen off jam nut on header levelling bolt (E).
Access to nut is through slot (D).
3. Adjust bolt (E) until header is level.
4. Tighten jam nut to secure the position.
HEADER FLOTATION
IMPORTANT:
To avoid
- frequent breakage of sickle components
- scooping soil
- soil build-up at cutterbar in wet conditions,
set header float as light as possible without
causing excessive bouncing.
Ensure float indicator (C) is at bottom of gauge
and stays in the 0 – 3 range during operation.
Damage to header and adapter may occur when
operating above 5 on the gauge.
Float settings vary with header type. For draper
headers under normal conditions, adjust float
spring tension so 50 to 70 lbs. force (220 to 300 N)
is required to lift cutterbar at each end. See
recommended float setting in your Header
Operator’s Manual.
To adjust header float on adapter:
1. Lower cutterbar to the ground.
2. Loosen springs, if required, so that both
working pins (A) are tight in the slots as shown.
NOTE:
The slots provide the float range. Pin
(A) is shown at the bottom of the float range.
3. Tighten bolts (B) (two per side) to increase float
(which makes header lighter at cutting height).
Loosen bolts to decrease float (which makes
header heavier at cutting height).
NOTE:
Both springs on one side should be
adjusted equally (same exposed bolt length).
Due to weight differences side-to-side,
adjustments will differ from one leg to the other.
4. When adjustment is complete, force required to
lift cutterbar should be approximately the same
at both ends. Check that both pins (A) are tight
in the slots, as shown, with the pin against the
bottom of the slot in adapter frame, and against
the top of the slot in vertical link (V). If not,
springs have been over-tightened, and should
be loosened to provide proper float.
NOTE:
To determine if header is floating at
cutting height, check for clearance between pin
(A) and the bottom of slot in vertical link (V). If
there is no clearance, header is not floating.
