IMPORTANT: If the cutting edge of the blade has already
been sharpened to within 1 5/8" from the edge, or if any
metal separation is present, replace the blades with new
ones. See Figure 7-2.

• It is important that each cutting blade edge be ground
equally to maintain proper blade balance.
• A poorly balanced blade will cause excessive vibration
and may cause damage to the tractor and result in per-
sonal injury. The blade can be tested by balancing it on
a round shaft screwdriver. Grind metal from the heavy
side until it balances evenly.
IMPORTANT: When replacing the blades, make certain the
side of the blade marked ''Bottom'' faces the ground when
the mower is turned to the operating position.
IMPORTANT: Note that the stars of the blades (and spin-
dles) are not symmetrical. The blade can be installed on
each spindle in only one direction. Carefully align the star
hole of the blade with the star of the spindle shaft when
installing each blade. DO NOT improperly align the blade
and spindle shaft, and attempt to seat the blade onto the
spindle by tightening the hex flange nut.
• Rotate the blade as necessary to align its star hole
with the star of the spindle shaft, then slide the blade
onto the spindle shaft. Thread the hex flange onto the
spindle shaft and use a torque wrench to tighten the
hex flange nut to 70 to 90 foot-pounds.
• Repeat the above procedure to install the other blade.
Changing the PTO Belt
WARNING: Be sure to shut the engine off,
remove ignition key, disconnect the spark plug
wire(s) to prevent unintended starting before
removing the belt(s).
All belts on your tractor are subject to wear and should be
replaced if any signs of wear are present.
IMPORTANT: Do not use substitute belts. The V-belt found
on your tractor is specially designed for optimal perfor-
mance and service life for your deck application. Use only
OEM original replacement belts.

To replace the PTO belt, proceed as follows:
• Remove the deck from beneath the tractor (refer to Cut-
ting Deck Removal).
• Maneuver the PTO belt downward and off the idler
pulley on the spring loaded idler bracket. NOTE: It may
be necessary to loosen the hex cap screw and flange
lock nut securing the pulley to the idler bracket to fit
the belt between the pulley and bracket. Slide the belt
between the bottom of the idler pulley and top of the
timing belt idler pulley below. See Figure 7-3.

• Loop the belt and push out of the V- groove of the drive
pulley on the right hand spindle assembly. Lift the belt
over the pulley and out from beneath the spindle cover.
See Figure 7-3.
• Loop the new PTO belt and slide between the top of
the drive pulley and spindle cover. Maneuver the belt
around and into the V-groove of the drive pulley.
• Route the back side of the belt around idler pulley and
between the idler pulley and idler bracket. Re-tighten
the hex screw and flange lock nut if loosened earlier.
Refer to Figure 7-3.
• Route the belt around the fixed idler pulley as shown
in Figure 7-3 and re-install the deck as described in "Re-
installing the Cutting Deck" later in this section.
Changing the Timing Belt
WARNING: Be sure to shut the engine off,
remove ignition key, disconnect the spark plug
wire(s) to prevent unintended starting before
removing the belt(s).
To replace the timing belt, proceed as follows:
• Remove the deck from beneath the tractor (refer to Cut-
ting Deck Removal).
• Remove the PTO belt drive pulley of the right hand
spindle assembly as described in "Changing the PTO
Belt."
• Remove the hex screw, flat washer, lock washer, shoul-
der spacer, and flange lock nut that make up the idler
bracket backstop. NOTE: It may be necessary to clean
the underside of the mowing deck to access the hex
screw. Refer to Figure 7-4.
