Mower blade maintenance
Check the mower blades daily, they are the key to power
efficiency and well groomed turf. Keep the blades 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.
WARNING
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 steering 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 a rock, branch or other foreign object during mow-
ing!
WARNING
Always wear adequate eye protection when grinding
mower blades.
