Mower Blade Replacement
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 118 ft-lbs
(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.

injury.
