10 ADJUSTMENT
10.2 BEDKNIFE ADJUSTMENT
NOTE: If the backlap valve accessory (Part
No. 2702016) is installed, the backlap valve
control lever must be in the centre "neutral"
position so that the reels can be rotated
manually.
Any adjustment to the clearance between the
reel blades and the bedknife should be done at
the leading end of the reel first (the end at
which each individual blade first crosses the
bedknife). Then at the opposite end of the reel.
1. Loosen the lower adjustment screws at each
end by turning them approximately
1/4 turn counterclockwise (See Figure
10.2.2).
2. While rotating the reel backwards, turn the
upper adjustment screws (leading end first)
until there is approximately .001, (.025mm)
clearance. After adjusting both ends, recheck
the leading end.
NOTE:
between the bedknife and the blades will
result in poor cutting quality. Too little
clearance will cause excessive wear to the
cutting edges and may cause damage to the
bedknife, reel blades or other components.
3. Using a wrench rotate the reel forward. The
reel must turn freely and you should just be
able to hear the reel blades making slight
contact with the bedknife (See Fig. 10.2.1.).
4. After the bedknife is properly adjusted, tighten
the lower adjustment screw at each end.
5. Test the cutting head by holding two strips of
newsprint perpendicular to the bedknife.
Rotate the reel with a wrench. The reel must
turn freely and each blade on the reel should
cut one of the two strips of paper.

WARNING
To avoid the possibility of serious injury,
NEVER attempt any cutting head
adjustments while the engine is running.
WARNING
NEVER rotate the cutting reel by pushing
it with your hands or fingers. Fingers can
become caught between the reel and the
frame resulting in serious injury. Use a
ratchet with a 9/16" socket on the end of
the reel shaft to rotate it during
adjustments and testing.
