Servicing The Blade - Toro Groundsmaster 3500-G Operator's Manual

4. Rotate the marked end of the blade to the 3 o'clock and
9 o'clock positions and measure the heights
5. Compare the 12 o'clock position measured height to
the height-of-cut setting.
Note: It should be within 0.7 mm (0.03 inch). The 3
o'clock and 9 o'clock heights should be 3.8 ± 2.2 mm
(0.15 ± 0.09 inch) higher than the 12 o'clock setting
and within 2.2 mm (0.09 inch) of each other.
If any of these measurements are not within specification,
proceed to Adjusting the Blade Plane (page
Adjusting the Blade Plane
Start with the front adjustment (change 1 bracket at a time).
1. Remove the height-of-cut bracket (front, left, or right)
from the deck frame
1. Height-of-cut bracket
2. Adjust the 1.5 mm (0.06 inch) shims and/or 0.7 mm
(0.03 inch) shim between the deck frame and bracket
to achieve the desired height of cut
3. Install the height-of-cut bracket to the deck frame with
the remaining shims assembled below the height-of-cut
bracket (Figure 66).
4. Secure the socket-head bolt and spacer and flange nut.
Note: The socket-head bolt and spacer are held
together with Loctite to prevent the spacer from falling
inside the deck frame.
5. Verify the 12 o'clock position setting and adjust if
needed.
6. Determine if you need to adjust only 1 or both (right
and left side) height-of-cut brackets.
Note: If the 3 o'clock or 9 o'clock side is 3.8 ± 2.2
mm (0.15 ± 0.09 inch) higher than the new front
height, then you do not need to adjust for that side.

Removing the Blade
Replace the blade if it hits a solid object, the blade is out
of balance, or if the blade is bent. Always use genuine
Toro replacement blades to ensure safety and optimum
performance. Never use replacement blades made by other
manufacturers, because they could be dangerous.
1. Perform the pre-maintenance procedure; refer to
Preparing the Machine for Maintenance (page
2. Block the cutting deck to prevent it from falling
accidentally.
3. Grasp the end of the blade using a rag or thickly
padded glove and remove the blade bolt, anti-scalp cup,
and blade from the spindle shaft
