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
95).
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 regains some up and down adjustment on
each of the 4 deck links.

On both sides of the deck, measure from the
level surface to the back tip of the blade (position
B). Ensure the measurement is 8.3 cm (3-1/4
inches)
(Figure

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.

Measure until all 4 sides are the correct
height. Tighten all the nuts on the deck lift arm
assemblies.
Servicing the Cutting
Blades
g027345
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Blade Safety
A worn or damaged blade can break, and a piece of
the blade could be thrown toward you or bystanders,
resulting in serious personal injury or death. Trying to
repair a damaged blade may result in discontinued
safety certification of the product.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the
blades or wear gloves, and use caution when
servicing the blades. Only replace or sharpen the
blades; never straighten or weld them.
•
On multi-bladed machines, take care as rotating 1
blade can cause other blades to rotate.
Before Inspecting or Servicing the
Blades
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2.
Shut off the engine, remove the key, and
disconnect the spark-plug wires from the spark
plugs.
