able through most hardware supply stores.
The blade should not lean or tilt. When spinning the blade
slowly it should not wobble. Balance the blade before rein-

IMPORTANT: Refer to the Safety section of this manual for
blade handling safety information.
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
®
Turf Equipment.
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 160.0 N•m
when reinstalling blades.
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 point-
ing upward toward the inside of the deck to ensure proper
cutting.
