Servicing The Front Roller - Toro Groundsmaster 3500-G Operator's Manual

Inspecting the Blade Plane
1. Remove the hydraulic motor from the cutting
unit and remove the cutting unit from the traction
unit.
Note:
Use a hoist (or a minimum of 2 people)
and place the cutting unit on a flat table.
2. Mark an end of the blade with a paint pen or
marker.
Note:
Use this end of the blade to check all
heights.
3. Position the cutting edge of the marked end
of the blade at the 12 o'clock position (straight
ahead in the direction of mowing) and measure
the height from the table to the cutting edge of
the blade (Figure
Figure 64
4. Rotate the marked end of the blade to the 3
o'clock and 9 o'clock positions and measure the
heights (Figure 64).
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
(page 51).
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 cutting unit frame
64).

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 cutting unit
frame and bracket to achieve the desired height
of cut
3. Install the height-of-cut bracket to the cutting
unit frame with the remaining shims assembled
below the height-of-cut bracket
4. Secure the socket-head bolt and spacer and
flange nut.

Note:
held together with thread-locking compound to
prevent the spacer from falling inside the cutting
unit 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:
6.0 mm (0.06 to 0.24 inch) higher than the new
front height, then you do not need to adjust for
that side. Adjust the other side to within ± 2.2
mm (0.09 inch) 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. Verify the 12, 3, and 9 o'clock heights.
