Cutting Height - MacDon A30-S Operator's Manual

6.17.7 Cutting Height

Cutting height is controlled with a combination of
skid shoes or gauge rollers, and header angle
adjustment - not with the header lift cylinders.
Having the header "ride" on the skid shoes
allows the float linkage to float header over
obstacles, and follow ground contours, rather
than supporting header with the cylinder.
Lowering the skid shoes or gauge rollers
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.
WARNING
To avoid bodily injury or death from
unexpected start-up
machine, stop engine, remove key, and
engage lift cylinder lockout valves before
going under machine to adjust skid shoes or
for any reason.
6.17.7.1 Cutting Height Adjustment:
a. Raise header, and engage lift cylinder lockouts.
b. Remove pins (A) at each skid shoe or gauge
roller.
