the grass cut ends will be ragged and usually turn
brown soon after mowing. For best results, remove
the blade and sharpen if on a grinding wheel at an angle
of 22 to 28 degrees, The cutting surface should extend
in about 2 1/2" from the tips. Check the blade after
sharpening to determine that it is still balanced. It will
