OPERATION
CUTTING HEIGHT
Your header will be equipped with either:
• wide adjustable outer skid shoes, or
• gauge rollers plus narrower skid shoes.
Vary the cutting height by adjusting either skid
shoe or gauge roller position. The operator can
then lower the header to the ground, allowing the
shoes or rollers to provide a consistent cutting
height.
NOTE: Lowering the skid shoes or gauge rollers
raises the cutting height. (Gauge rollers allow
higher settings than skid shoes.) This may be
desirable in stony conditions, to reduce damage to
cutting components. Other benefits include
reduced plugging due to mud or dirt build-up and
longer stubble for faster drying.
WARNING: To avoid bodily injury or
death from unexpected start-up or
fall of raised header; stop engine,
remove key and engage header lift cylinder
stops before going under header to adjust skid
shoes or gauge rollers (or for any reason).
