Servicing the Cutting Blades
Maintain sharp blades throughout the cutting season because
sharp blades cut cleanly without tearing or shredding the grass
blades. Tearing and shredding turns grass brown at the edges,
which slows growth and increases the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.
Blade Safety
A worn or damaged blade can break, and a piece of the blade
could be thrown toward you or bystanders, resulting in serious
personal injury or death. Trying to repair a damaged blade
may result in discontinued safety certification of the product.
•
Inspect the blades periodically for wear or damage.
•
Use care when checking the blades. Wrap the blades or
wear gloves, and use caution when servicing the blades.
Only replace or sharpen the blades; never straighten or
weld them.
• On multi-bladed machines, take care as rotating 1 blade
can cause other blades to rotate.
Before Inspecting or Servicing the
Blades
1. Park the machine on a level surface, disengage the
blade-control switch (PTO), and engage the parking
brake.
2. Shut off the engine, remove the key, and disconnect the
spark-plug wires from the spark plugs.
Inspecting the Blades
Service Interval: Before each use or daily
1. Inspect the cutting edges ( Figure 101 ).
2. If the edges are not sharp or have nicks, remove and
sharpen the blade; refer to
Sharpening the Blades (page
69) .
3. Inspect the blades, especially in the curved area.
4. If you notice any cracks, wear, or a slot forming in this
area, immediately install a new blade (
Figure 101 ).
