Mower Blade Maintenance

Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades sharp. A dull
blade will tear rather than cut the grass, leaving a brown ragged
top on the grass within a few hours. A dull blade also requires
more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING
Never attempt to straighten a bent blade by heating, or
weld a cracked or broken blade as the blade may break
and cause serious injury. Replace worn or damaged
blades.
WARNING
Never work with blades while engine is running or deck
clutch switch is engaged (on). Always place deck clutch
switch in the disengaged position, place steering control
levers in the park brake position and turn engine off and
disconnect negative battery cable. Block up mower when
you must work under it. Wear gloves when handling
blades. Always check for blade damage if mower
strikes a rock, branch or other foreign object during mow-
ing!
WARNING
Always wear adequate eye protection when grinding
mower blades.

Mower Blade Removal

Use a 15/16" wrench to remove the 5/8" cap screw holding
the blade to the spindle shaft from underneath. NOTE: A blade
holding tool (part number 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
Sharpen the blades on a grinder following pattern as shown
(Figure 4-11). Touch-up sharpening can be done with a file
Check the blades for balance following grinding. A
commercial balancing tool is available through most hardware
supply stores, or balancing can be done by placing the blade on
an inverted line punch or 5/8" bolt. Blade should not lean or tilt.
Spin the blade slowly, blade should not wobble. If blade is out
of balance, true it up before reinstalling.
Lay the blade on a flat surface and check for distortion
(Figure 4-12 & Figure 4-13). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or
undercut threads. Torque bolts on spindles to 118 foot-pounds

(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 cut-
ting.
IMPORTANT: When mounting blades, rotate them after
installation to ensure blade tips do not touch each other or sides
of the mower.
Failure to correctly torque the bolt may result in the loss
of the blade which can cause serious injury.
Mower blades are sharp and can cut. Wrap the blade(s) or
wear gloves and use extra caution when servicing them.
Do not sharpen to original pattern (below). It is
easier to get a straight cutting edge following
the resharpening pattern shown above.
