OPERATION
Header Flotation
The following suggested header float settings are a starting point for normal conditions
. Your specific
requirements and conditions may require heavier or lighter float.
Force required to lift the cutterbar off ground at each end of the header (with lift cylinders fully retracted):
910/920/932 Auger Headers: 100 to 120 lbs. (445 - 535 N)
912/922/933 Auger Headers & 942 Multi-Crop Header: 75 to 85 lbs. (335 - 380 N)
Draper Headers: 50 to 70 lbs. (220 - 310 N)
Benefits of lighter float settings
:
1. Less cutting component breakage in rough or stony conditions.
2. Avoids soil build-up at cutterbar in wet conditions.
Benefits of heavier float settings
:
1. When cutting very close to the ground, enables the cutterbar to follow ground contours.
NOTE: For all headers except 12’ & 15’ 972
Header, use top hole (A) in float linkage. For 12’ &
15’ 972 Header, use lower hole (B).
To adjust header float:
NOTE: Because of end-to-end weight differential,
dimension (C) at left and right drawbolt will be
different to achieve equal float at both ends of
header. Also, lighter headers will require a larger
dimension (C), heavier headers a smaller
dimension (C).
1. Raise header fully, shut off engine, remove key.
2. Loosen nut (D).
3. Turn spring drawbolt (E) clockwise to increase
float
(which makes header lighter when lowered to ground).
Turn bolt counter-clockwise to decrease
float (which
makes header heavier when lowered).
4. Tighten nut (D) to lock position.
5. Lower header fully and check float at both ends of
cutterbar. Force required to lift cutterbar should be
approximately the same at both ends.
IMPORTANT: Spring loaded gauge wheels (available
on some draper headers) have an effect on header
float. See “Header Floatation” in your header
operator’s manual for details.
