Installing the Blades
Important:
The right-hand blade on this mower deck
is counter-rotating and uses a left-hand threaded blade
bolt. UseFigure 102 for the correct placement of the
mower blades.
1.
Install the left and center blades, curved washers, and
blade bolts to the spindle shafts (Figure 101 and Figure
102).
Note:
Ensure the curved part of the blade is pointing
upward toward the inside of the mower deck to ensure
proper cutting.
Note:
Ensure the curved-washer cone is installed
towards the bolt head (Figure 101).
2.
Install the right blade, curved washer, and blade bolt
(left-hand threaded bolt) to the spindle shaft (Figure
101 and Figure 102).

Removing the Mower Deck
Before servicing or removing the mower deck, lock out the
spring loaded deck arms.
WARNING
Deck lift arm assemblies have stored energy.
Removing the deck with out releasing the stored
energy can cause serious injury or death.
Do Not attempt to disassemble the deck from the
front frame without locking out the stored energy.
1.
Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2.
Remove the height adjustment pin and lower the deck
to the ground.
3.
Place the height adjustment pin in the 7.6 cm (3 inch)
cutting height location. This locks the deck lift arms in
the lowest position when the deck is removed and the
stored energy in the deck spring is released.
4.
Remove the belt covers.
5.
Lift up the floor pan and insert a ratchet into the square
hole in the deck idler (Figure 103).
