Groomer Reel Service
Inspect groomer reel blades frequently for damage and
wear. Straighten bent blades with a pliers. Either replace
worn blades or reverse the blades to put the sharpest
blade edge forward (Fig. 7). Blades that are rounded to
the midpoint of the blade tip must be reversed or re-
placed for best groomer performance.
Disassembly (Fig. 8)
1. Remove groomer reel from cutting unit (see Groom-
er Reel Removal in this section).
2. Remove seal guards from groomer reel.
3. Remove lock nut from either end of the shaft (Fig. 8).
4. Remove spacers and blades from groomer shaft. If
needed, remove second lock nut from shaft.
Assembly (Fig. 8)
1. Install lock nut on drive end of groomer shaft. Place
first spacer and then first blade on shaft. Adjust location
of lock nut so first blade is 6.850” (174 mm) from drive
end of groomer shaft (Fig. 9).
2. Alternately install remaining spacers and blades
making sure that all blades are separated by a spacer.
Additionally, rotate location mark on each installed blade
one flat of the shaft, either in a clockwise or counter-
clockwise direction. The direction of location mark rota-
tion must remain constant on the shaft.
3. When all blades have been installed, place final
spacer on shaft and then thread second lock nut onto the
shaft.
4. Using wrench on shaft flats to prevent shaft from
turning, torque second lock nut from 200 to 250 in−lb
(22.6 to 28.3 N−m). After torquing lock nut, spacers
should not be free to rotate.
5. Place seal guards on groomer shaft. Position seal
guard on drive end of shaft (with key slot) 3.570” (90.7
mm) from shaft end. Position seal guard on non−drive
end of shaft 1.740” (44.2 mm) from shaft end (Fig. 9).
6. Install o−ring on non−drive end of groomer shaft.

er Reel Installation in this section).
