3 Blade Sharpening

For best results mower blades must be kepl sharp. The blades can be sharpened with a few strokes of a tile or on a grinding wheel We suggest they be sharpened after every 25 hours oi mowing Do not attempt to sharpen while on mower fl you mow in sandy soil check the bfades after each two mowings The sand wears lhe blades away rapidly,

aWhen gr_ndmg care should be taken to matntain blade balance and the blade should be checked

for proper balance before retnstattanon on mower

Unbalanced or bent blade wilt cause excessive

vtbrat_on when running and eventual damage to

mower or engine Replace bent or damaged blades

b,. To check blade balance, drive a nail into a beam or waiL Leave about one inch (25_4 mm) of the straight nail exposed. Place center hole of clean blade over the head of the nail (Fig. 21). NOTE:

CENTER HOLE OF BLADE ON NATL. IF BLADE 1S PROPERLY BALANCED, BLADE SHOULD REMAIN IN POSITION SHOWN IN FIG. 21_ IF EITHER END OF THE BLADE MOVES DOWN-

WARD, BLADE IS NOT BALANCED. SHARPEN THE HEAVY END UNTIL BLADE IS BALANCED
