Cutting Blades

.
To properly sharpen the cutting blades, remove equal
amounts of metal from both ends of the blades along the
cutting edges, parallel to the trailing edge, at a 25°- to 30°
angle. Always grind each cutting blade edge equally to
maintain proper blade balance. See Fig. 7-4.
WARNING! Shut the engine off and remove
ignition key before removing the cutting blade(s) for
sharpening or replacement. Protect your hands by
using heavy gloves when grasping the blade
CAUTION: If the cutting edge of the blade has
previously been sharpened, or if any metal
separation is present, replace the blades with new
ones.
WARNING! Periodically inspect the blade and/or
spindle for cracks or damage, especially after you’ve
struck a foreign object. Do not operate the machine
until damaged components are replaced.
WARNING! A poorly balanced blade will cause
excessive vibration, may damage to the tractor and/
or result in personal injury.
To remove the blades, proceed as follows.

flip the deck over to expose its underside.

spindle assembly. See Fig. 7-3.

Test the blade’s balance using a blade balancer. Grind
metal from the heavy side until it balances evenly.
NOTE: When replacing the blade, be sure to install the blade with
the side of the blade marked ‘‘Bottom’’ (or with a part number
stamped in it) facing the ground when the mower is in the
operating position.
