Servicing The Cutting Blades - Toro Z Master Commercial 3000 Series Operator's Manual

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 88).
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
should regain some up and down adjustment on
each of the 4 deck links.

14. Tighten 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
tip.
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) (Figure 85).
16. Fine-tune the screw adjuster by turning it to
attain to the 8.3 mm (3-1/4 inch) height
86).
To increase the height, turn the adjustment
nut clockwise; to decrease the height, turn it
counterclockwise.
17. Measure until all 4 sides are the correct
height. Tighten all the 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 at you
or bystanders, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
