GEAR BOX REMOVED
TIMING BLADES:
For blade replacement, timing does not have to be
done via the belts. The spindle shaft hole in the
blade provides various attaching positions.
1. Place a mark across all pulleys in line with cutting
blade.
2. Position marks on outer pulleys lengthwise with
mower and center pulley mark crosswise.
3. Install belts and slide center pulley on shaft.
4. Adjust nut on belt tension bolt until length of
spring is 4-3/8", Fig. 10.1.
5. Tighten bolts holding spindle assembly in mower
deck and complete reassembly.
REPLACING BLADES
To keep blade from turning while loosening bolt,
place a 2"x4" or similar block between blade and
deflector under mower. Note order components are
taken off so they can be replaced same way. Blades
are attached to spindle by means of blade adaptor,
two shear pins and a bolt with a belleville spring
washer and lockwasher.
When sharpening blades on a grinder, take care not
to overheat or metal will lose its temper and become
soft. Grind each blade edge equally so that blade
balance will be maintained. Replace blade and at¬
taching parts in same order as removed. Tighten nut
to 45 ft.-lbs. torque.
NOTE: Mower blades must be properly timed. The
two outboard blades must be in line (parallel to each
other) and center blade at 90 degree (perpendicular
to outboard blades.)
