ADJUSTMENTS 8
8.13 BEDKNIFE ADJUSTMENT CLASSIC XP™ REELS _________________________
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
counterclock- wise.
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.
.
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.
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.
NOTICE
Too much clearance 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.
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.
