OPERATION
CUTTING HEIGHT
Control cutting height with skid plates, not with the
hydraulic cylinder. Having the header "ride" on the
skid plates allows the 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.
NOTE: Left and right skid plates are standard
equipment. An additional two inner skid plates may
be added if required.
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.
