6 ADJUSTMENTS
6.1 GENERAL ________________________________________________________________
1. Adjustments and maintenance should always be
performed by a qualified technician. If proper
adjustment cannot be made, contact an authorized
Textron Turf Care And Specialty Products Dealer.
2. Replace, do not adjust, worn or damaged
components.
3. Long hair, jewelry or loose fitting clothing may get
tangled in moving parts.
4. Do not change governor settings or overspeed the
engine.
6.2 BEDKNIFE________________________________________________________________
1. Adjust bedknife by turning handles (D) on each end
of the unit. Turn the handles clockwise to bring
bedknife closer to reel and counter-clockwise to
move it away.
a. When adjusting the bedknife to meet the reel,
both adjusting handles must be drawn up simul-
taneously. Turn the handles by hand, do not use
tools.
b. Be sure that both ends of the bedknife are
always adjusted evenly to the reel. Adjusting
only one side will cause the bedknife and reel to
wear at an angle or taper.
c. Always start adjustment at the leading edge of
the reel, followed by the trailing end. The leading
end of the blade is the end that passes over the
bedknife first during normal rotation.
2. Turn handles to close gap between reel and
bedknife until slight resistance is felt sliding a feeler
gauge or shim stock .001 in. (.025 mm) between
reel blade and bedknife. Do not turn reel.
3. Repeat for trailing end of the reel in the same
manner then recheck the adjustment at the leading
end.
4. When properly adjusted, the reel will spin freely and
you should be able to cut a piece of newspaper,
along the full length of the reel, when the paper is
held at 90°.
5. Mowers are equipped with a spacer (E) to provide
greater spring pressure to the bedknife shoe. When
spring (F) is fully compressed, remove spacer to
allow an additional 5/16 in. (8 mm) adjustment.
