SECTION 10: MOWER BLADE MAINTENANCE
10.1 Check mower blades after each use. This is essential for maintaining well-groomed turf. Keep
the blades sharp. If a dull blade is used for cutting, the grass will tear rather than cut. This
could damage the grass leaving a brown frayed top on the grass within a few hours. A dull
blade will also require more power from the engine.
10.2 NEVER attempt to straighten a bent blade by heating. NEVER attempt to weld a cracked
blade. The blades can break and cause serious injury or death.
10.3 NEVER work with blades while engine is running or deck clutch is engaged.
10.4 ALWAYS place deck clutch in DISENGAGE position while performing maintenance.
10.5 Use blocks when you MUST work under mower.
10.6 ALWAYS wear thick gloves when handling blades.
10.7 ALWAYS check for blade damage if mower strikes rock, branch, or other objects that could
potentially damage the blade.
(REMEMBER: NEVER CHECK BLADE WHILE ENGINE IS ON!
NEVER CHECK BLADES WHILE BLADES ARE ENGAGED!)
SECTION 11: GREASING THE BEARINGS
11.1 Park the machine on a level surface and disengage the blade control switch.
11.2 Move the motion control levers outward to the neutral position, engage parking brake, stop
the engine, remove the key, and wait for all moving parts to stop before leaving the operating
position.
11.3 Grease Type: NGLI grade #2 multi-purpose gun grease. Grease the front caster pivots.
11.4 Clean the grease fittings with a cloth. Scrape any paint off the front of the fitting(s).
11.5 Connect a grease gun to each fitting. Pump grease in fittings until grease begins to seep out
of the bearings. Wipe up excess grease.
11.6 Refer to service manual section for grease fitting locations.
