Mower blade maintenance
Check the mower blades daily, they are the key to power efficiency and
well groomed turf. Keep them sharp, a dull blade will tear rather than cut
the grass, leaving a brown ragged top on the grass within a few hours. A
dull blade also requires more power from the engine.
Replace any blade which is bent, cracked or broken.
WARNING:
Never attempt to straighten a bent blade by heating,
or weld a cracked or broken blade as the blade may break and
cause serious injury. Replace worn or damaged blades.
DANGER:
Never work with blades while engine is running or
deck clutch switch is engaged (on).
Always place deck clutch switch in the
disengaged
position, place control
levers in the park brake position and turn engine off and disconnect
negative battery cable. Block up mower when you
must
work under it.
Wear gloves when handling blades.
Always check for blade damage
if
mower strikes rock, branch or other foreign object during mowing!
Mower blade removal
Use a 15/16" wrench to remove the 5/8" cap screw holding the blade to
the spindle shaft from underneath.
Sharpen the blades on a grinder following pattern as shown (Fig. 4-20).
Touch-up sharpening can be done with a file.
Check the blades for balance following grinding. A commercial
balancing tool is available through most hardware supply stores, or
balancing can be done by placing the blade on an inverted line punch or
5/8" bolt. Blade should not lean or tilt. Spin the blade slowly, blade should
not wobble. If blade is out of balance, true it up before reinstalling.
Lay the blade on a flat surface and check for distortion (Fig. 4-21 and 4-
22). Replace any distorted blade.
Do not re-use spindle bolts which have stripped, worn or undercut
threads. Torque bolts on spindles to 118 foot-pounds when reinstalling
blades.
IMPORTANT:
The blade sail (curved part) must be pointing upward
toward the inside of the deck to ensure proper cutting.
WARNING:
When mounting blades, rotate them after
installation to ensure blade tips do not touch each other or sides of
the mower.
WARNING:
Failure to correctly torque the bolt may result in the
loss of the blade which can cause serious injury.
