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 

rocks, branches, 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:

 

EQUIPMENT LUBRICATION

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.

HOW TO CHOOSE THE RIGHT BLADE

Essentially there are only TWO basic styles of mowing blades used or approved for use on our current 
products: 

1) The standard style of mowing blade is essentially designed for cutting grass and effectively discharging

the clippings out from the deck to fall onto the lawn or to be captured in a grass collection system.
Standard blades are also referred to as “2-in-1” (discharging & bagging ) or “high-lift” blades (because
they are designed to create a higher-lifting airflow).

2) Mulching blades generally have a more curved style surface and frequently include extra cutting

surfaces along the blade edges. These blades may also come in a “+” design (which is actually two
individual blades arranged in a perpendicular fashion to enhance mulching). The “+” blades are usually
found on older style mowers; newer ones utilize blades with more advanced mulching technology.
Mulching blades may also be referred to as “3-in-1” (mulching, discharging & bagging) or “all-purpose”
blades.

Bear in mind that the re-circulating airflow design of 3/1 blades makes them less efficient at discharging 
grass clippings than a standard 2/1 blade. As with most all-purpose tools, there is some give and take as 
opposed to using a tool designed for a more specific purpose.

If you’re experiencing less-than-desired cutting or discharging performance with a 3/1 blade, you may want 
to check into using a 2/1 blade. Conversely, if you’re using a 2/1 blade and want to mulch clippings, you 
should see about the availability of mulching blades or a mulching kit.*

The type of blade installed on a new mower is a decision the retailer makes for each model of mower, based 
on the expected needs of most customers. If you’re unsure of which blade is on a particular model, inspect 
the blade. Blades have part numbers stamped into them. Then compare these part numbers with the unit’s 
Operator’s Manual or Parts List.

It is true there are many other styles of blades available. But since we don’t manufacture or recommend 
using these other aftermarket styles, we will leave them out of this discussion. Should you want more 
information on special application or aftermarket blades, you should contact the companies that make these 
products. NOTE: Customers using non-OEM blades do so at their own risk. The use of unapproved (non-
OEM) blades may void any or all of the mower and engine factory warranties.

* MULCHING KITS – These generally consist of mulching blades and a mulching plug (which closes off
the discharge opening to keep the clippings contained under the deck for re-cutting) plus any necessary
hardware for installation. Please check with your parts distributor regarding the contents of a particular
mulching kit.
