13. 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 (Figure 89).
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 four deck links.

Single point adjustment bolt
14. Tighten the two bolts at the bottom of the height of
cut plate (Figure 88). Torque to 27-33 ft-lb (37-45
N-m).
Note:
In most conditions, the back blade tip should
be adjusted 1/4 inch (6.4 mm) 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 3 1/4 inches (8.3 cm)
(Figure 86).
16. Fine-tune the adjustment nut on the front deck lift
assembly by turning it (Figure 87).
To increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
17. Measure until all four sides are the correct height.
Tighten all the jam nuts on the deck lift arm
assemblies.
18. Lower 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, you
may want to keep extra blades on hand.
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 (Figure 90). If the edges
are not sharp or have nicks, remove and sharpen the
blades. Refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area
(Figure 90). If you notice any damage, wear, or a slot
forming in this area (Figure 90), immediately install a
new blade.
