Brush Mower
Removing the Blades
NOTE: Some of these steps require two people.
To change, sharpen, or service the blades in any way,
it is not necessary to remove the spindle shaft and
blade carrier. Follow these steps if you are only
removing the blades:
1. Park the mower on a level surface, with the ignition
switch off, the key removed, and the blades
disengaged. Also, disconnect the spark plug wires
from the spark plugs and ground them against the
engine to prevent inadvertent starting. Block the
rear wheels to prevent accidental rollback.
2. Remove the pulley guard and visual warning disk.
3. Remove the blade nut access cover located near
the blade pulley.
4. Using a socket, extension, and pull handle remove
the blade pivot retaining nut.
5. Remove the blade pivot. It may
be necessary to tap the pivot
out of the blade carrier. Note:
If tapping is necessary,
replace the nut on the blade
pivot, without the locking
washers, about half the
thickness of the nut. Place a
block of wood or other flat
surface between the hammer and blade pivot and
nut so the impact is flat. ONLY impact the nut, not
the threads of the pivot.
6. Remove the blades and pivots from underneath the
mower.
7. Perform the desired blade
service. If you are replacing the
blades, replacing the pivots is
also recommended .
8. Replace the carrier protector,
pivots, and blades making
certain the keys are inserted in the
pivots as they were removed. You will
need assistance to start the nuts on the
pivot bolts through the access hole.
Operating Instructions
Beware of the cutting edges on the blades.
The rotation of one blade may cause the other
blade(s) to rotate. Always wear work gloves
when handling blades.
9. Tighten the blade pivot nuts properly.
10. Refasten the access hole cover to the deck to
prevent debris from entering underneath the guard.
11. Inspect the work done to the blade system to make
certain everything is properly secured. Note:
Check to be sure blades rotate freely.
12. Replace the mower guard and the visual warning
disk and secure both properly.
13. Start the engine and blades safely and properly. If
any unusual noises or vibrations are present, SHUT
THE MOWER DOWN IMMEDIATELY.
REPLACE THE BLADE SYSTEM IF ANY PART APPEARS
TO BE WORN OR DAMAGED IN ANY WAY. DO NOT
USE THE MOWER WITH ANY PART OF THE BLADE
SYSTEM DAMAGED. BLADES MUST BE REPLACED IN
PAIRS TO PREVENT VIBRATION.
To disassemble the blade carrier, spindle shaft, and
spindle, follow steps 1 through 6 to remove the blades
and then proceed with the following additional steps:
1. Insert a pipe or rod through the access hole and
the blade carrier hole.
2. Loosen the spindle shaft retaining nut on the top of
the pulley. Have an assistant hold the pipe or rod
upright while loosening the bolt. DO NOT allow the
rod to tilt and become jammed from the blade
carrier turning motion.
3. Raise the front end of the mower using a jack and
secure the mower with jack-stands.
4. Remove the spindle shaft retaining nut. You will
need to hold the shaft on the bottom side.
CAUTION: The blade carrier is heavy. When the nut
is removed the blade carrier can slide out of the
spindle easily.
5. After servicing and inspecting the spindle, replace
the carrier and spindle shaft, and start the nut on
top to prevent the carrier from falling out. This will
require two people.
6. Place the pipe back through the access hole, and
tighten the spindle shaft retaining bolt.
7. Using a jack, lower the brush mower back to the
ground.
