5.9
Mower Blade Service
5.7 Mower blade sharpness should be checked daily or prior to each usage. A sharp blade in good condition is
essential in obtaining an efficient quality of cut. A dull worn blade will tear the grass instead of cutting the
grass, potentially leaving a brown ragged top on the grass within a few hours. Dull blades also require
more power to operate.
5.7.1 Damaged Blade… Any blade which is bent, cracked or broken must be replaced.
5.7.2
Blade Removal
… Remove the 5/8 inch blade bolt using a 15/16 inch wrench. The blade spindle
can be held from turning by using by blocking the blade rotation with a block of wood.
5.7.3 Blade Sharpening… The blades can be sharpened with a grinder or touched up with a file. Note
the angle of the cutting edge and try to maintain when sharpening.
5.7.4 Blade Balance… Check the blade balance after sharpening. There are a variety of blade balancing
techniques and commercial blade balancing tools available through a majority of hardware supply
stores. If the blade is out of balance, true it up before re-installing.
5.7.5 Blade Straightness… Lay the blade on a flat surface and check to make sure both cutting edges
are in the same cutting plane. Replace blade if warped or distorted.
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
Make sure the Ignition and Blade Engagement Switches are off, Drive Lever(s) in neutral lock,
Brake on, and Negative battery cable disconnected prior to servicing.
Warning
Wear the appropriate Personal Protective Equipment (PPE) when operating and/or servicing
the mower. It is required that the operator or servicing personnel wear protective eye wear,
hearing protection, hand protection and/or foot protection.
