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 lockout 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 lockouts.
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.
