Turn the mower Off, remove the safety key from the stop handle and lift the mower up to a position
allowing you to inspect its mowing deck and blades – Use heavy gloves when reaching towards the
mowing deck, mowing disk and blades.

make sure blades rotate freely
7. Are the blades dull? Replace blades as needed
8. Is the mowing height set too low for a very high grass? Return to Step 1.
