mowing) (Figure 12) and measure height from table
to cutting edge of blade.
9:00
5. Rotate the marked end of the blade to the 3 and 9
o'clock positions (Figure
6. Compare the 12 o'clock measured height to the
height-of-cut setting. It should be within 0.030 inch
(0.7 mm). The 3 and 9 o'clock heights should be
0.150±.090 inch (3.8±2.2 mm) higher than the 12
o'clock setting and within 0.090 inch (2.2 mm) of each
other.
If any of these measurements are not within specification,
proceed to Adjusting the Blade Plane.
Adjusting the Blade Plane
Start with the front adjustment (change one bracket at a time).
1. Remove the height-of-cut bracket, (front, left, or right)
from the deck frame
2. Adjust 0.060 inch (1.5 mm) shims and/or 0.030 inch
(0.7 mm) shim between the deck frame and bracket to
achieve the desired height setting

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
Loctite 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 one or both (right-hand and
left-hand) height-of-cut brackets need to be adjusted.
If the 3 or 9 o'clock side is 0.150±0.090 inch (3.8±2.2
mm) higher than the new front height then no
adjustment is needed for that side. Adjust the other
side to within ±0.090 inch (2.2 mm) of the correct side.
7. Adjust the right and/or left height-of-cut brackets by
repeating steps
8. Secure the carriage bolts and flange nuts.
9. Again, verify the 12, 3, and 9 o'clock heights.

Removing the Cutter Blade

The blade must be replaced 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, shut the
engine off, 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

3. Install the blade, sail facing toward the cutting deck,
with the anti-scalp cup and blade bolt
