Installing the Blades
Note: Ensure that you install the red-colored blade
on the right side.
1. Install the blade driver to the new blades with
the shear bolts and locknuts ( Figure 66 ).
2. T orque the shear bolts to 922 to 1 130 N∙m (80
to 100 in-lb).
Note: Align the blade-driver ats with the ats
on the shaft when installing the blade on the
mower deck.
3. Install the blade, washer , and blade bolt to the
spindle shaft ( Figure 66 ).
4. T orque the blade bolt to 1 15 to 149 N∙m (85-1 10
ft-lb).
5. Lower the mower deck to the operating position.
Refer to Lowering the Mower Deck to the
Operating Position ( page 18 ) .
W ARNING
Operating a mower deck with loose or
weakened blade bolts can be dangerous.
A loose or weakened blade bolt could
allow a blade rotating at a high speed
to come out from under the mower
deck, causing serious injury or property
damage.
• Replace the blade bolt after striking a
foreign object.
• Use only genuine T oro replacement
parts.
• Do not lubricate the threads of the
bolt or spindle before assembly .
Leveling the Mower Deck
1. Park the machine on a level surface, move the
speed-control lever to the N EUTRAL position,
disengage the blade-control switch (PT O), and
engage the parking brake.
2. Shut of f the engine, remove the key , and wait
for all moving parts to stop before leaving the
operating position.
3. Check the tire pressure in the drive tires; refer to
Checking the T ire Pressure ( page 47 ) .
4. V erify that all hairpin cotters are in the 7.62
cm (3 inch) mower-deck-height holes with the
spacers under the hairpin cotters ( Figure 69 ).
