5. Use a torque wrench to tighten the blade bolt to
54 N∙m.
Important: A bolt torqued to 54 N∙m is very tight.
While holding the blade with a block of wood,
put your weight behind the ratchet or wrench and
tighten the bolt securely. This bolt is very difficult
to overtighten.
Blade Sharpening
A slightly worn blade may be re-sharpened. Both
blade edges must be sharpened equally to ensure
balance. Sharpen the blade every 25 mowing hours
or more frequently if conditions require.
Remove the blade from the mower and clean using
a brush and water. Inspect the blade for signs of
damage. Sharpen both cutting edges with a flat file
to restore performance. Figure 25.

Ensure that the blade is balanced. Use a screwdriver
with a round shaft to support the blade through
its centre hole. Hold the blade horizontal and then
release. A balanced blade will remain horizontal.

If the blade is not balanced the heavy end will rotate
downwards. Sharpen the heavy end until the blade
is correctly balanced. Figure 27.
