6. Compare 12 o’clock measured height to the height of
cut setting. It should be within .03 inch. The 3 and 9
o’clock heights should be .15
±
.03 inch higher than the
12 o’clock setting and within .03 in. of each other.
If any of these measurements are not within specification,
proceed to Adjusting the Blade Plane, page 9.
Adjusting the Blade Plane
Start with front adjustment (change one bracket at a time).
1. Remove height-of-cut bracket, (front, left, or right)
from deck frame (Fig. 11).
2. Adjust .06 in. shims and/or .03 in. shim between the
deck frame and bracket to achieve the desired height
setting (Fig. 11).

Shims
3. Install height-of-cut bracket to deck frame with
remaining shims assembled below the height-of-cut
bracket.
4. Secure socket head bolt/spacer and flange nut.
Note: Socket head bolt/spacer are held together with
Loctite to prevent spacer from falling inside the deck
frame.
5. Verify 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 .15
±
.03 in. higher than the new front
height then no adjustment is needed for that side. Adjust
other side to within
±
.03 in. of correct side.
7. Adjust right and/or left height-of-cut brackets by
repeating steps 1 thru 3.
8. Secure carriage bolts and flange nuts.
9. Again, verify 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 cutting deck to highest position, shut the engine
off, and engage the parking brake. Block cutting deck to
prevent it from falling accidentally.
2. Grasp end of blade using a rag or thickly padded glove.
Remove blade bolt, anti-scalp cup, and blade from
spindle shaft (Fig. 12).

Anti-scalp cup
3. Install blade, sail facing toward cutting deck, with
anti-scalp cup and blade bolt (Fig. 12). Tighten blade
bolt to 85–110 ft.-lb. (115–149 N
⋅
m).
Danger
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator’s or
bystander’s area, resulting in serious personal
injury or death.
•
Inspect the blade periodically for wear or
damage.
•
Never weld a broken or cracked blade.
•
Always replace a worn or damaged blade.
