BELT REPLACEMENT

Belt tension is maintained by a spring loaded
idler, controlled by the clutch bail. No belt tension
adjustment is necessary when proper belts are
used.
NOTE: A matched pair of belts must be used for
correct operation. if one belt needs to be replaced,
you MUST replace both belts to assure proper belt
tension.
1. remove belt guards and old belts from unit.
2. Place the new belts between the idler pulley E
and the snubber F on the idler arm and then over
the engine and reel pulleys.
3. install the belt guards. Make sure the belt guide
rods G are outside of the belt.
BLADE REPLACEMENT
Fixed Blade Reels - to replace worn or damaged
blades or to change to different blade and/or
spacer combination.
1. remove reel assembly from chassis.
2. remove bearing from end of shaft (opposite
the pulley end). Loosen the set screw securing
the locking collar. With a small punch, tap the
bearing approximately one quarter turn in the
opposite direction of the reel rotation. this
relieves the cam lock action of the bearing so it
can be removed from the shaft.
3. Hold the shaft to keep it from turning and remove
the shaft nut. remove the blades and spacers
from the shaft and replace or rearrange as
required.
NOTE: When reassembling the reel, it is important to
start and end with a spacer. DO NOT assemble
with a blade next to the shaft nut at either end.
Fixed blades must be placed on the shaft in a
pattern 60 off center from the previous
o
blade.
4. re-install the shaft nut and tighten securely to
keep the blades from coming loose.
5. re-install the reel bearing by exactly reversing
the steps taken to remove it.
BELT/BLADE REPLACEMENT
NOTE: Blades that are worn on one cutting face may
be reversed and used again.
Flail Blade reels
Work on only one of the six blade shaft
assemblies at a time.
1. remove reel assembly from chassis.
2. remove the cotter pin from one end of one of the
blade shafts and pull the shaft out.
3. replace the blades and other worn parts and
re-assemble in the proper order while sliding the
shaft back into place.
4. replace blades only in sets to maintain balance.
5. install a new cotter pin to secure the shaft.
