•
If the deck is too low, tighten the front
height-adjustment bolt (
Figure 73 ) by rotating
the bottom nut clockwise.
•
If the deck is too high, loosen the front
height-adjustment bolt (
Figure 73 ) by rotating
the bottom nut counterclockwise. Fine-tune
the rear adjusters as required.
Adjust the rear wheel height ( Figure 73 ) so that
the rear wheel lightly touches the ground with
minimal pressure.
4. Measure the back of the wing blades. If either
has less than 1.5 mm (1/16 inch) rake, raise the
rear of the deck by tightening the left and right
rear adjustments (
Figure 73 ) until all 4 blades
have a minimum of 1.5 mm (1/16 inch) rake.
Adjust the rear wing wheels so that they lightly
touch the ground with minimal pressure. Tighten
all 4 rear hanger-mount locations (
Figure 73 ).
5. Tighten the front and rear height-of-cut hanger
jam nuts.
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.
Servicing the Cutting
Blades
To ensure a superior quality of cut, keep the blades
sharp. For convenient sharpening and replacement,
keep extra blades on hand.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage
the blade-control switch, and engage the parking
brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 74 ).
2. If the edges are not sharp or have nicks, remove
and sharpen the blade; refer to
Sharpening the
Blades (page 63) .
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 74 ).
