Mower Blade Maintenance
Blade Inspection
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
DO NOT try to straighten a blade that is bent. Never weld a
broken or cracked blade. ALWAYS replace with a new Land
Pride blade to assure safety.
!
DANGER
Never work with blades while engine is running or blade is
engaged. Always place blade engagement switch in the down
(Off) position, place both control levers in neutral position,
place park lever in (ON) position and turn engine off. 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!
