Maintenance
C.
Set the gap between the spring and bracket to
3/4–7/8 inch (19–22 mm).
Adjusting the Blade Slope
1.
Check the front-to-rear blade level. If the front
blade tip is not “R” (see Block Height and Rake
Table in
Deck Leveling
) lower than the rear
blade tip, adjust the blade level using the following
instructions:
2.
Park the machine on a level surface and disengage
the blade control switch.
3.
Move the motion control levers outward to the
neutral position, engage the parking brake, stop
the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
4.
Check the air pressure of all four tires. If needed,
adjust to the recommended inflation; refer to
Checking the Tire Pressure
in Drive System
Maintenance section.
5.
Check and adjust the side-to-side blade level if
you have not checked the setting; refer to
Deck
Leveling
.
6.
Set the height-of-cut lever to the 3 inch (76 mm)
position. Place two “B” thick blocks (see Block
Height and Rake Table in
Deck Leveling
) under
the rear edge of the cutting deck skirt; one on
each side of the cutting deck. Place two “A” thick
blocks (see Block Height and Rake Table in
Deck
Leveling
) under each side of the front edge of the
deck, but not under the anti-scalp roller brackets.
7.
Loosen the leveling adjust locking nuts (item 1
Figure 70) on all four corners so that the deck is
sitting securely on all four blocks. Make sure that
the slack is removed from the deck hangers and
the deck lift foot lever is pushed back against the
stop, then tighten the four leveling adjust locking
nuts.
8.
Carefully rotate the blades so they are facing front
to rear (Figure 71).
9.
For 60 Inch Decks Only:
A.
Raise the deck to the transport (5 inch (12.7
cm) cutting height) position.
B.
Slowly loosen the adjusting screw on the
lift assist spring until the screw can be
removed (see Figure 69). Save the screw for
reinstallation.
10.
Measure from the tip of the front blade to the flat
surface and the tip of the rear blade to the flat
surface (Figure 71). If the front blade tip is not
“R” (see Block Height and Rake Table in
Deck
Leveling
) lower than the rear blade tip, adjust the
front deck hanger.
