If the deck is too low, tighten the
single-point-adjustment bolt by rotating it clockwise. If
the deck is too high, loosen the single-point-adjustment
bolt by rotating it counterclockwise (
).
Note:
Loosen or tighten the single-point-adjustment
bolt enough to move the height-of-cut plate-mounting
bolts at least 1/3 the length of the available travel
in their slots. This will regain some up-and-down
adjustment on each of the 4 deck links.

Single-point-adjustment bolt
14.
Torque the 2 bolts at the bottom of the height-of-cut
plate (
) to 37 to 45 N∙m (27 to 33 ft-lb).
Note:
For most conditions, adjust the back blade tip
6.4 mm (1/4 inch) higher than the front.
15.
On both sides of the deck, measure from the level
surface to the back tip of the blade (Postion B). The
measurement should read 8.3 cm (3-1/4 inches); refer
to
.
16.
Fine-tune the adjuster screw by turning it to get 8.3
mm (3–1/4 inches) height (
).
To increase the height, turn the adjustment nut
clockwise; to decrease the height, turn the nut
counterclockwise.
17.
Measure until all 4 sides are the correct height. Tighten
all the jam nuts on the deck-lift arm assemblies.
18.
Lower the discharge chute.
Servicing the Cutting 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, keep extra blades
on hand.
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 (
). If the edges are
not sharp or have nicks, remove and sharpen the blades.
2.
Inspect the blades, especially the curved area (
). If you notice any damage, wear, or a slot forming
in this area (
), immediately install a new blade.
