Installing The Mower Deck
• Slide the mower deck under the Z-Series, making
sure belt covers are removed.
• From the rear, reach under the muffler cover and
grasp the belt from the mower deck and bring it
between the hydraulic units.
• Bring the belt between the pulley and the clutch. Do
not put the belt into the pulley grove yet.
• From the front of the Z-Series, hold both front lift
rods up and slide the mower deck forward until the
lift rods go into the bracket.
• Slide the mower deck backwards to insert the front
lift rods into the brackets. See Figure 25.
• Align the mower deck so the lift link aligns with the
hanger bracket on the mower deck. See Figure 27.

• Pull the support pin out and align with holes in
hanger bracket and lift link.
• Release the support pin so that it goes through both
holes to secure deck. Repeat these steps for other
side of the deck.
• From the rear, attach the belt around the clutch
pulley.
• Engage tension bar by moving it into the bracket to
maintain belt tension and replace belt covers.
Mower Blades
WARNING: The mower blades are sharp
and can cause severe injury. Always
protect hands by wearing heavy leather
work gloves to grasp blades.
• Secure the mower blade by putting a piece of wood
between the blade and the housing. See Figure 28.
• Remove the hex flange nut that secures the blade
to the spindle assembly.
Figure 28
It is extremely important that each cutting blade edge
be ground equally to maintain proper blade balance. An
unbalanced blade will cause excessive vibration when
rotating at high speeds, may cause damage to the unit,
or result in personal injury. The blade can be tested by
balancing it on a round shaft screwdriver. Grind metal
from the heavy side until it balances evenly.
When replacing the blade, be sure to install the blade
with the side of the blade marked “Bottom” (or with a
part number stamped in it) facing the ground when the
mower is in the operating position.
IMPORTANT:
Tighten the hex nut that secures mower
blade to spindle to 100 ft-lbs.
WARNING: Periodically inspect the blade
adapter for cracks, especially if you strike
a foreign object. Replace when necessary.
