Removing The Cutter Blade - Toro 30834 Operator's Manual

4. Position the cutting edge of the marked end of the
blade at 12 o'clock (straight ahead in the direction of
mowing) (Figure 12) and measure height from table
to cutting edge of blade.

Figure 12
5. Rotate the marked end of the blade to the 3 and
9 o'clock positions (Figure 12) and measure the
heights.
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 (Figure 13).
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 (Figure 13).

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 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 1 through 3.
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 (Figure 14).
