OPERATION
OPERATING VARIABLES (continued)
3. REEL POSITION (continued)
After adjusting reel position:
a. Check that the reel rotates freely. Tines must not contact feed pan, header beam, guards or ground.
b. Check that the reel is adjusted to the same position on both sides. Reel tube should appear parallel to
header beam from both side and front.
c. Check header float and adjust if required. See "Header Flotation" in this section.
4. CUTTING HEIGHT
Control cutting height with skid plates, not with the
hydraulic cylinder. Having the header "ride" on the
skid plates allows the three-point float linkage to
float header over obstacles and follow ground
contours, rather than supporting the header with
the cylinder.
NOTE: Lowering the skid plates raises the cutting
height. This may be desirable in stony conditions,
to reduce damage to cutting components. Also, a
longer stubble length helps material dry faster.
To adjust cutting height:
WARNING: To avoid bodily injury or
death from unexpected start-up or
fall of raised machine, stop engine,
remove key and engage lift cylinder
stop before going under machine to
adjust skid plates or for any reason.
a. Remove pin (A) at each skid plate.
b. Raise or lower skid plate (B) to desired
position.
c. Replace pin (A).
After adjusting cutting height:
a. Check that skid plates are adjusted to the
same position.
b. Check header float and adjust if required. See
"Header Flotation" in this section.
WARNING: Stones or other foreign objects carried into the conditioner rolls can be ejected
with force in ANY direction. Keep everyone several hundred feet away from your operation
and be sure you are adequately protected. See "General Safety" in Safety section for
recommended protective wear.
