1. Height-of-cut bracket
3. Install the height-of-cut bracket to the deck
frame with the remaining shims assembled
below the height-of-cut bracket.
4. Secure the socket-head bolt/spacer and flange
nut.
Note:
Socket-head bolt/spacer are held
together with thread-locking adhesive to prevent
the spacer from falling inside the deck frame.
5. Verify the 12 o'clock height and adjust if needed.
6. Determine if only 1 or both (right and left)
height-of-cut brackets need to be adjusted. If
the 3 or 9 o'clock side is 1.6 to 6.0 mm (0.06 to
0.24 inch) higher than the new front height then
no adjustment is needed for that side. Adjust the
other side to within 1.6 to 6.0 mm (0.06 to 0.24
inch) of the correct side.
7. Adjust the right and/or left height-of-cut brackets
by repeating steps 1 through 3.
8. Secure the carriage bolts and flange nuts.
9. Again, verify the 12, 3, and 9 o'clock heights.

Removing and Installing a
Blade
Replace the blade if a solid object is hit, the blade is
out of balance, or if the blade is bent. Always use
genuine Toro replacement blades to be sure of safety
and optimum performance. Never use replacement
blades made by other manufacturers because they
could be dangerous.
1. Raise the cutting deck to the highest position,
turn the key in the ignition switch to the O
position, and engage the parking brake. Block
the cutting deck to prevent it from falling
accidentally.
2. Grasp the end of the blade using a rag or thickly
padded glove. Remove the blade bolt, anti-scalp
cup, and blade from the spindle shaft
96).
