Cutterblade Sharpening

A slightly worn cutterblade may be re-sharpened. Both blade edges

30°-45°￿

must be sharpened equally to ensure balance. Sharpen the cutterblade every 25 mowing hours or more frequently if conditions require. Remove the cutterblade from the mower and clean using a brush and water. Inspect the cutterblade for signs of damage.

Sharpen both cutting edges with a flat file to restore performance.

Ensure that the cutterblade is balanced. Use a screw driver with a round shaft to support the cutterblade through its centre hole. Hold the cutterblade horizontal and then release. A balanced cutterblade will remain horizontal.

If the cutterblade is not balanced the heavy end will rotate downwards.

Sharpen the heavy end until the cutterblade is correctly balanced.
