Cutting Blades; V-Belts - Husqvarna 967 678901-00 Operator's Manual

MAINTENANCE

Cutting Blades

To attain the best mowing effect, it is important
that blades are well sharpened and not damaged.
Replace blades that have been bent or cracked
when hitting obstacles.
CAUTION! Blades are sharp. Protect
your hands with gloves and/or wrap blades with
a heavy cloth when handling.
The sharpening of blades should be
carried out by an authorized service
workshop.
Let the service workshop decide whether a blade
with large nicks can be repaired/ground or must
be replaced. Balance the blades after sharpening.
Check the blade mounts.
Blade Replacement
1. Remove blade bolt by turning it counter
clockwise.
2. Install new or resharpened blade with
stamped GRASS SIDE facing towards
ground/grass (down) or THIS SIDE UP facing
deck and cutter housing.
3. Install and tighten blade bolt securely.
4. Torque blade bolt to 90 ft-lbs (122 Nm).
IMPORTANT INFORMATION Special blade
bolt is heat treated. Replace with a Husqvarna
bolt if required. Do not use lower grade

Deck Belt
Deck Belt Removal
Park the mower on a level surface and engage

2. Remove dirt or grass that may have
accumulated around the cutter housings and
entire deck surface.
3. Remove the belt guide hardware with a 1/2"
wrench and set the belt guide aside.

opening in the idler arm, shift the arm counter

housing pulleys.

the routing decal on the cutting deck.

the center spindle pulley.

counter clockwise. When there is enough
slack, slip the belt onto the center spindle
pulley.

the routing decal and that the belt does not
have twists.
