the machine to achieve 6 to 10 mm (1/4 to 3/8 inch)
lower in front at A than in the rear at B

chains and adjust again if needed.

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.
DANGER
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
