Cutterblade Sharpening

30° -45°	A slightly worn cutterblade may be re-sharpened. Both blade edges
	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.
