Blade Plane Inspection/Adjustment - Toro Groundsmaster 3500-D Service Manual

Blade Plane Inspection and Adjustment
If a solid object is struck by the cutting deck, the blade
plane of the deck should be inspected.
Blade Plane Inspection
1. Remove cutting unit to be inspected (see Cutting
Unit Removal and Installation).
2. Use hoist (or minimum of two people) and place cut-
ting deck on flat table.
3. Mark one end of blade with paint pen or marker. Use
this end of blade to check all heights.
4. Position cutting edge of marked end of blade at 12
o'clock (straight ahead in direction of mowing). Measure
height from table to cutting edge of blade.
5. Rotate marked end of blade to the 3 and 9 o'clock
positions and measure heights.
6. Compare 12 o'clock measured height to the height--
of--cut setting. It should be within .090 inch (2.3 mm).
The 3 and 9 o'clock heights should be .150 + .090 inch
(3.8 + 2.3 mm) higher than the 12 o'clock setting and
within .090 inch (2.3 mm) of each other. If any of these
measurements are not within specification, proceed to
Adjusting Blade Plane.
Adjusting Blade Plane
Start with front bracket adjustment and change one
height--of--cut bracket at a time.
1. Remove height--of--cut bracket (front, left, or right)
from deck frame.
2. Position .060 inch and/or .030 inch shims between
the deck frame and bracket to achieve the desired blade
height setting.
3. Install height--of--cut bracket to deck frame with re-
maining shims assembled below the height--of--cut
bracket.
NOTE: Socket head bolt and spacer for front bracket
are held together with Loctite to prevent spacer from fal-
ling inside the deck frame.
4. Secure front height--of--cut bracket to deck frame
with socket head bolt/spacer and flange nut.
5. Verify 12 o'clock height. Re--adjust if needed.

6. Determine if one or both (RH and LH) height--of--cut
brackets need to be adjusted. If the 3 or 9 o'clock side
is .150 + .090 inch (3.8 + 2.3 mm) higher than the new
front height, then no adjustment is needed for that side.
Adjust other side (if needed) to within + .090 inch (+ 2.3
mm) of correct side.
7. Adjust right and/or left height--of--cut brackets by re-
peating steps 1 thru 3.
8. Secure right and/or left height--of--cut brackets with
carriage bolts and flange nuts.
9. Verify 12, 3, and 9 o'clock heights.
