Cutting Height Adjustment - Husqvarna W436 Operator's Manual

Cutting Height Adjustment

WARNING! ALWAYS block wheels,
engage parking brake and know all jack
stands are strong, secure and able to hold
weight of unit during maintenance.
Adjust the cutting height using a combination
of the mounting location on the deck carrier
frame, spacers on the front casters and
spacers between the mower blades and the
deck spindles. The desired cutting height may
be set by adjusting only the blade spacers and
caster spacers.
Refer to the cutting height charts below to
determine which combination of location and
spacers will set the desired cutting height.
1. Support the rear of the machine and the
back edge of the mower deck.
2. Remove the six deck mounting bolts (three
per side, lower bolt not shown).
3. Align the mounting holes in the deck
frame with the unit frame and reinstall the
mounting bolts in the appropriate holes
and tighten to 35 –40 lbf-ft (47– 54 N•m).
IMPORTANT To prevent damage to the
unit, always disengage the drive and come
to a complete stop before changing gears.
4. Using a suitable lifting device, lift the front
of the machine.

IMPORTANT The washer must always be
installed on top the lower HOC spacers.
6. Adjust caster wheel spacers to set the
front cutting height accordingly.
7. Remove the mower blade from the spindle
and place the appropriate number of ¼"
spacers (washers) between the spindle
and the blade.
NOTE: If two or three spacers are
removed, shorter blade bolts must be
used. The bolts for this application are
mounted under the belt cover.
CAUTION! Blades are sharp.
Protect your hands with gloves
and/or wrap blades with a
heavy cloth when handling. On
multi-blade mowers, rotation of
one blade will cause all blades
to rotate.
IMPORTANT DO NOT allow the blade to
be less than /
1
the mower deck.
8. Replace mower blade and tighten blade
bolt to 120 lbf-ft (163 N•m).
9. Remove supports from deck and mower
frame.
NOTE: Store the unused ¼" spacers on
hex bolts mounted on the rear of the deck.
