OPERATION
CUTTING HEIGHT (continued)
HAY AND SPECIALTY CROPS
Skid Shoes / Gauge Rollers
In hay and other specialty crops and conditions
where it is desirable to cut close to the ground, use
skid shoes to vary cutting height. The operator can
then lower the header to the ground, allowing the
shoes to provide a consistent cutting height.
NOTE: Lowering the skid shoes raises the cutting
height. 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.
DANGER: 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 for
any reason).
Skid shoes have two settings to provide a coarse
adjustment for cutting height. Height can then be
fine-tuned with header angle adjustment. See
"Header Angle" in this section.
To change skid shoe position:
1. Loosen front bolt, securing skid shoes.
2. Remove hardware at shoe (A), both ends of
header. Position shoe at the desired setting,
and install hardware. Retighten front bolt.
NOTE: When end skid shoes are not required,
shoes and bolt-on brackets (C) may be
removed.
3. For windrower applications, also loosen
hardware at shoe (B) at both header legs. Tap
the shoe up or down to end of slot and tighten
hardware. (Extreme ends of slot will
correspond to end shoe settings.)
NOTE: Adjust all shoes to the same height to
provide an even cutting height.
NOTE: In conditions where soil adheres to steel
shoes, bolt-on plastic shoes are available from
your dealer.
Gauge Rollers are available to replace end skid
shoes in conditions where shoe wear is too rapid.
Adjustment of roller height is similar to skid shoes.
