New Holland 499 Operator's Manual page 35

CUTTING HEIGHT
The cutting height is controlled by the skid shoe and
cutter bar tilt settings. Five skid shoe positions, 1, are
available to vary the stubble height from 25 mm-152
mm (1"- 6").
DANGER
Always engage the transport stops when
working around a raised head or transporting the
machine on the highway. Failure to comply will
result in death or serious injury.
Remove the hairpin cotter and drilled pin to change
skid shoe position. Always position left and right skid
shoes in the same hole. In stony conditions, lower the
skid shoes for a longer stubble to prevent cutter bar
damage.
WARNING
If stones and other foreign objects are carried
into the conditioner rolls, the objects can be
deflected toward the operator, possibly resulting
in physical injury or death.
NOTE: Readjust the header flotation springs after
changing the skid shoes.
HEADER FLOTATION
WARNING
Disengage the PTO, turn off the tractor engine
and remove the key. Wait for all movement to
stop before leaving the operator's position.
Never adjust, lubricate, clean or unplug machine
with the engine running. Failure to comply could
result in death or serious injury.
IMPORTANT: Shift the tongue to the transport
position and lower the header before checking or
adjusting header flotation.
NOTE: In stony or rough field conditions, set the
flotation lighter [23 Kg (50 Lbs.)] to protect the cutter
bar. Use a slower ground speed in rough conditions
to avoid excessive header bouncing and cutter bar
damage.
Adjust the header flotation spring, 1, so 32 kg (70
lbs.) maximum starts to lift the header off the ground
at either end of the push bar. Loosen the jam nuts and
turn the spring bolts as required. Retighten the jam
nuts.
