6.17.7 Reel Tine to Header Pan Clearance
IMPORTANT
The above dimensions are provided as
guidelines only. Tines may slightly contact
the guards but not the knife sections or
the auger pan.
a. Rotate reel slowly by hand, and check tine
clearance at knife and pan. Flex tines to
simulate crop-loaded position to ensure tine
clearances to knife sections and auger pan
are adequate for working conditions.
b. Check that reel rotates freely.
IMPORTANT
If there are a few reel tine fingers that are
touching the pan while the rest are at the
correct height, trim the longer tines to
match the rest. Be sure to adjust both
sides of the reel. Ensure that tines do not
contact the plastic header pan.
6.17.8 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.
NOTE
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 or fall of raised
machine, stop engine, remove key, and
engage lift cylinder lock-out valves before
going under machine to adjust skid shoes or
for any reason.
6.17.8.1 Cutting Height Adjustment:
a. Raise header, and engage lift cylinder lock-outs.
b. Remove pins (A) at each skid shoe or
gauge roller.
c. Raise or lower skid shoe or gauge roller to
desired position.
d. Replace pins (A).
e. Check that skid shoes or gauge rollers are
adjusted to the same position.
f. Check header float, and adjust if required. Refer
to Section 6.17.10 Header Flotation.
NOTE
LH and RH skid shoes are standard
equipment. Two more inner skid shoes
may be added if required. A set of two
gauge rollers may be installed in place
of the outer skid shoes.
