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 dealer for more information.
Sharpen the blades on a grinder following pattern as shown
(Figure 9-7). Touch-up sharpening can be done with a file.
Check the blades for balance following grinding.
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 1/2" 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 9-8 & Figure 9-9). 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 nm) when reinstalling blades.
IMPORTANT: When mounting blades, rotate them after
installation to ensure blade tips do not touch each other or sides
of the mower.
WARNING: Failure to correctly torque the bolt may
result in the loss of the blade which can cause serious
injury.
WARNING: Mower blades are sharp and can cut.
Wrap the blade(s) or wear gloves and use extra caution
when servicing them.

The steering control levers can be adjusted for operator
comfort. By loosening the cap screws that attaches the upper
control lever to the lower lever (Figure 9-14), the upper control
lever can be pivoted to fit the operator's personal preference.
The steering control levers should be adjusted so that they
align with each other when in the neutral position
