HEADER FLOTATION
Header flotation springs are normally set so 70 lbs. force (311 N) is required to lift either end of the header just
off the ground.
In rough or stony conditions, it may be desirable to change setting to 35-50 lbs. (156-222 N) to protect cutting
components.
NOTE: When float setting is light, it may be necessary to use a slower ground speed to avoid excessive
bouncing and leaving a ragged cut.
To increase header flotation, which decreases the force required to lift header:
a. Raise header fully.
b. Back jam nut (A) away from spring.
c. Turn adjuster bolt (B) further into spring to
increase flotation.
d. Tighten jam nut (A) against spring insert
(C) to secure the setting.
e. Lower header and check header flotation
at each end.
IMPORTANT: Float setting (or lifting force)
must be equal on both springs. Weight
difference between left and right ends
requires different spring lengths to achieve
equal float at both ends. Note that other
operating variable adjustments may affect
float setting. Check the float and readjust if
necessary after adjusting reel position, cutting
height, or header angle. Also, if using a
tractor with drawbar height different than 16
inches (406 mm) flotation will be affected.
Adjust as required.
FEED PAN / ROCK DROP TINE POSITION
The rear of the feed pan is adjustable up and down
to raise or lower the feed pan and rock drop tines.
• Move down in heavy crop to prevent plugging of
bulky material.
• Move up in light crop for even windrow
formation.
• To adjust, loosen hardware (D) both sides and
position rock drop tine support as required.
• Align pointer at each side of rock drop tine
support with slot to match crop condition:
Light Crop – Upper slot
Normal Crop – Center slot
Heavy Crop – Lower slot
NOTE: Use pointer to align with slot, not tines
which are aligned above the pointer as shown.
• Tighten hardware (D) both sides.
