14. Tighten the 2 bolts at the bottom of the
height-of-cut plate (
Figure 99 ).
Note:
In most conditions, the back blade tip
should be adjusted 6.4 mm (1/4 inch) higher
than the front.
15. Torque the 2 bolts to 37 to 45 N∙m (27 to 33 ft-lb).
16. On both sides of the deck, measure from the
level surface to the back tip of the blade (postion
B) as shown in
Figure 96 .
Note:
The measurement should read 8.3 cm
(3-1/4 inches).
17. Fine tune the screw adjuster by turning it to get
8.3 mm (3-1/4 inches) height (
Figure 98 ).
To increase the height, turn the adjustment nut
clockwise; to decrease, turn counterclockwise.
18. Measure until all 4 sides are the correct height.
19. Tighten all of the nuts on the deck-lift-arm
assemblies.
20. Lower the discharge chute.
Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
you may want to 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.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 101 ).
2. If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Sharpening the
Blades (page 68) .
3. Inspect the blades, especially in the curved area.
4. If you notice any cracks, wear, or a slot forming
in this area, immediately install a new blade
(
Figure 101 ).
