MAINTENANCE
2. Measure from the floor surface up to the
bottom of the blade tip on the discharge side
of the mower deck. Record this measurement.
3. Move to the opposite side; check that
measurement is the same. If adjustment is
required, loosen and adjust the front nuts until
the two side to side measurements are equal.
Retain measurement.
4. Turn the two outer blades to align with
the deck front to rear. Reposition the rear
mounting nuts up or down until the rear blade
tips are positioned 1/4" to 3/8" (6.35 mm -
9.525 mm) higher in the rear than the center
blade tips.
5. Confirm measurements once again. The
blade tip height must be 0-1/16" (0 mm -
1.588) side to side.
In the rear, the blade tips must be 1/4" to 3/8"
(6.35 mm - 9.525 mm) higher than the front
center measurement. In the front, blade tips
must be equal from side to side.
NOTE: This will place the mower deck in a
standard measurement position. Depending on
the type of grass being mowed or environmental
conditions, more adjustments may be required to
get the desired cut.

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 the
stamped part number facing towards the
ground/grass (down).
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
hardware than specified.
Anti-scalp Rollers
Anti-scalp rollers keep the deck in the proper
position to help prevent scalping in most terrain
conditions. Do not adjust the rollers to support the
deck.
IMPORTANT INFORMATION Adjust anti-scalp
rollers with the mower on a flat level surface. To
avoid deck damage, the anti-scalp rollers must
not be adjusted to support the deck.
Anti-scalp rollers can be set in three positions.
• Upper 1-1/2" to 2-1/2" (38 mm - 64 mm) grass
• Middle 2-1/2" to 4" (64 mm -102 mm) grass
• Lower 4" to 5" (102 mm - 127 mm) grass
The rollers must be approximately 1/4" from
ground. Do not adjust the rollers to support the
deck.
Park Brake
WARNING! Faulty adjustment will result
in reduced braking and can cause an accident.
Visually check that no damage is found on the
brake arms, cables, or park brake mechanism.
Check that there is sufficient braking action.
1. If the park brake is not performing correctly,
examine the brake arm pivot. With the park
brake disengaged, the brake arm pivot
bracket should have approximately 1/8"
