Servicing The Cutter Blade - Toro 30809 Operator's Manual

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 (Figure 67).
2. Adjust 1.5 mm (0.060 inch) shims and/or 0.7 mm
(0.030 inch) shim between the deck frame and bracket
to achieve the desired height setting (Figure 67).

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
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 3.8±2.2 mm (0.150±0.090
inch) higher than the new front height then no
adjustment is needed for that side. Adjust the other
side to within ±2.2 mm (0.090 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.

Servicing the Cutter Blade

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 (Figure 68).

3. Install the blade, sail facing toward the cutting deck,
with the anti-scalp cup and blade bolt (Figure 68).
Tighten blade bolt to 115–149 N-m (85–110 ft-lb).
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.
Inspecting and Sharpening the Blade
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. Examine the cutting ends of the blade carefully,
especially where the flat and curved parts of the blade
meet (Figure 69). Since sand and abrasive material can
wear away the metal that connects the flat and curved
parts of the blade, check the blade before using the
machine. If wear is noticed (Figure 69), replace the
blade; refer to Removing the Cutter Blade.
