Replacing the Blades
WARNING
Before performing any maintenance, place the PTO switch in the "OFF"
position, engage the parking brake lever, turn the ignition key to the
"OFF" position and remove the key from the switch. Protect your hands
by using heavy gloves when handling the blades. When servicing the
mower deck, be careful not to cut yourself on the sharpened blades.
Remove key from the ignition and disconnect the spark plug.
1.
Jack up the front of the mowing deck about one foot and block it
in that position.
2.
Wrap a rag around one end of the blade and grasp it to prevent
it from turning, or secure the blade by placing a block of wood
between the blade and the deck housing. See Figure 40.
3.
Use a 1-1⁄8" socket wrench on the pulley side of the spindle bolt.
4.
Remove the hex nut at the blade using a 1-1⁄8" wrench.
5.
Remove the blade.
6.
To replace the blade reverse the above process and tighten nut to
100-120 lb ft.
NOTE: Add a small amount of multi-purpose grease to the bolt threads
to avoid corrosion and galvanic corrosion.
WARNING
Never mow with dull blades. Blades that are bent should be replaced.
The cutting blades are sharp and can cause severe injury. Wrap the
cutting surface of the blade with a rag to avoid injury.
Sharpening the Blades
1.
Set the parking brake.
2.
Clean any debris from the blades. Keep blades sharp and free of
build-up at all times.
3.
Sharpen blades evenly at the original 30° angle to maintain blade
balance. Do not sharpen the underside of the blades. Use an
electric blade sharpener, a conventional electric grinder or a hand
file to sharpen the blades.
