MULCHING TIPS
Replacing the Cutting Blade
NOTE: INSPECT THE AREA WHERE THE MOWER IS TO BE USED, AND REMOVE ALL STONES, STICKS,
WIRE, BONES, AND OTHER DEBRIS THAT MIGHT BE THROWN BY THE ROTATING BLADE.
1. Release the switch to turn the mower OFF when crossing any graveled area (stones can be thrown by the
blade).
2. Set mower to the highest cutting height when mowing on uneven ground or in tall weeds.
3. For effective mulching, do not cut wet grass, because it tends to stick to the underside of the deck, preventing
proper mulching of grass clippings. New or thick grass may require a narrower cut. The ground speed should be
adjusted to the condition of the lawn. If mowing has been delayed and the grass has been allowed to grow longer
than 4" (10 cm), mow the lawn twice in order to reduce the grass height to a maximum of 3 1/4” (8.3 cm).
4. Walk at a steady pace. Overlap the cutting rows. Do not let the grass get too tall. If the grass gets too long, start
at the highest cutting position and work down to the desired cutting height.
WARNING:
If you strike a foreign object, stop the motor and disconnect the power cord. Thoroughly
inspect the mower for any damage. Repair any damage before operating the mower. Excessive vibration of
the mower during operation is an indication of damage. Thoroughly inspect the mower and repair any damage
before operating the mower.
WARNING:
Always protect your hands by wearing heavy gloves and/or wrapping the cutting edges with
rags or other materials when performing any maintenance on the blades.
Use only a YARDWORKS replacement blade (60-71
19-4
).
1. RELEASE THE SWITCH LEVER TO TURN THE MOWER OFF, WAIT FOR THE BLADE TO COME TO A
COMPLETE STOP
.
2. While wearing leather padded gloves, wedge a block of wood between the blade and the mower deck in order to
prevent the blade from turning when the nut is being removed.
3. Using a 15-mm wrench or socket, loosen the blade nut (1) and remove the blade (4). Turn the nut "CLOCKWISE"
to loosen it and "COUNTER-CLOCKWISE" to tighten it (this is a reverse rotation nut).
4. Remove the blade nut (1), the square washer(2), the insulator washer(3), and the blade.
5. To re-install the blade, position the blade with the cutting edges toward the ground. Assemble the blade nut, the
square washer, and the insulator washer as shown in Fig. 8. Using a 15-mm socket with a torque wrench, turn the
blade nut "COUNTER-CLOCKWISE” in order to secure the blade.
NOTE: Be sure to replace the parts in the exact order in which they were removed. When installing the cutting
blade, verify that it is installed with the curved ends pointing toward the mower deck, and not toward the ground.
