13. Tighten the two bolts at the bottom of the height of cut
plate
(Figure
94). Torque to 37-45 N-m (27-33 ft-lb).
Note: In most conditions, ensure the back, blade tip is
adjusted 6.4 mm (1/4 inch) higher than the front.
14. On both sides of the deck, measure from the level
surface to the back tip of the blade (Postion B). Ensure
the measurement is 8.3 cm (3-1/4 inches)
15. Fine tune the screw adjuster by turning it to get 8.3
mm (3-1/4 inches) height
To increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
16. Measure until all four sides are the correct height.
Tighten all the nuts on the deck lift arm assemblies.
Servicing the Cutting Blades
Important: The right-hand blade on this mower deck
is counter-rotating and uses a left-hand threaded blade
bolt. Use
Figure 99
for the correct placement of the
mower blades.
Maintain sharp blades throughout the cutting season because
sharp blades cut cleanly without tearing or shredding the grass
blades. Tearing and shredding turns grass brown at the edges,
which slows growth and increases the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.
(Figure

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.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the
blade-control switch (PTO), and set the parking brake. Turn
the ignition key to Off. Remove the key.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to
2. Inspect the blades, especially the curved area
96). If you notice any damage, wear, or a slot forming
in this area
(Figure
1. Cutting Edge
2. Curved Area
Checking for Bent Blades
1. Disengage the blade-control switch (PTO), move the
motion-control levers to the neutral-locked position
and set the parking brake.
2. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
3. Rotate the blades until the ends face forward and
backward
