Blades
Mower blade maintenance
Check the mower blades daily, they are the key to power effi-
ciency 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. Figure 6-9
Replace any blade which is bent, cracked or broken. Figure 6-
10 & Figure 6-11
Always place deck clutch switch in the disengaged position,
place neutral lock/park brake lever in the brake (engaged) posi-
tion, turn engine off, and remove ignition key when leaving the
unit. Remove the spark plug wires from the spark plugs, or, if
applicable, disconnect the negative battery cable. Block up
mower when you must work under it. Wear gloves when han-
dling blades. Always check for blade damage if mower strikes
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.
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 neutral lock/park
brake lever in the brake (engaged) position, turn engine
off, and remove ignition key when leaving the unit.
Remove the spark plug wires from the spark plugs, or, if
applicable, disconnect the negative battery cable. Block
up mower when you must work under it. Wear gloves
