Groomer Reel Service
Disassembly (Fig. 10)
Inspect groomer reel blades frequently for damage and
wear. Straighten bent blades with a pliers. Either replace
worn blades or reverse worn blades on the groomer
shaft to put the sharpest blade edge forward (Fig. 11).
Blades that are rounded to the midpoint of the blade tip
must be replaced or reversed for best groomer perfor-
mance.
1. Remove groomer reel (see Groomer Reel Removal
in this section).
2. Remove lock nut from either end of the shaft (Fig.
10).
3. Remove spacers and blades as necessary.
Assembly (Fig. 10)
1. Start by placing two spacers against a lock nut
installed on one end of groomer shaft. Then, place first
blade against spacers (Fig. 10).
Note: Early production groomer shafts were hex
shaped. Later production shafts have a D−shaped
cross−section. When installing groomer blades on ear-
lier, hex shaped shafts, rotate location mark on each
installed blade one flat of the shaft, either in a clockwise
or counterclockwise direction. The direction of location
mark rotation must remain constant on the shaft.
2. For 1/2 inch (1.3 cm) spacing, make sure there are
two spacers between blades (Fig. 10).
3. When all blades have been installed, place final 2
spacers on shaft and then thread lock nut onto the shaft.
4. Position lock nuts to allow blades and spacers to be
centered on the shaft (Fig. 12). Torque lock nuts from
200 to 250 in−lbs. (22.6 to 28.3 N−m) so spacers are
not free to rotate.
5. Install groomer reel back on cutting unit (see Groom-
er Reel Installation in this section).
