Mower blade removal
IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
Mower blades are sharp and can cut. Wrap the
blade(s) or wear gloves and use extra caution
when servicing them.
A 15/16" wrench is required to remove the 5/8" cap screw
holding the blade to the spindle shaft. NOTE: A blade holding
tool (P/N 381442) is available from Hustler
It is designed to prevent the blades from rotating when they
are being removed or installed on the spindle. Contact your
Hustler Dealer for more information.

Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts on spindles to 118 ft-lbs
(160.0 N•m) when reinstalling blades.
Failure to correctly torque the bolt may result in
the loss of the blade which can cause serious
injury.
Properly compressed cup washers maintain the correct
compression load on the blades. Replace the cup washers if
they are cracked or flattened.
IMPORTANT: The blade sail (curved part) must be
pointing upward toward the inside of the deck to ensure
proper cutting.
When mounting blades, rotate them after installation to
ensure blade tips do not touch each other or sides of the
mower.

Belts

Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of:
• severe cuts
• tears
• separation
• weather checking
• cracking
• burns caused by slipping.
Slight raveling of belt covering does not indicate failure,
trim ravelings with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the
case, otherwise, the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or
damage the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.

Deck Belt Adjustment

54"/60"/66"/72" XR7 Decks
The spindle belt tension remains constant by means of a
tension idler and spring. The spring tension should be such
that the belt does not slip under normal operating load
conditions, assuming the belt is not excessively worn or
damaged. As the belt stretches and wears in, adjustment
may become necessary. To increase belt tension, move the
spring chain one (or more) link(s) at the anchor point on the
deck frame. Figure 6-15 & Figure 6-16
