Lawn edgers remove grass and other debris that hang over a sidewalk or other paved surface from your lawn. A rapidly rotating blade slices into this turf or debris and shears it off in a straight vertical line with the ground. After many uses the blade gradually begins to dull until it no longer shears through the turf cleanly. A dull blade not only makes it harder to edge your lawn, but it can put unneeded wear and tear on your Ryobi edger. Ryobi edger blades are easy to change and are typically held on with one nut.
Turn the blade until the hole in the shaft lines up with the locking rod slot. Insert the locking rod into the hole. Turn the blade to see that it is locked in place.
Use a 5/8-inch box wrench and loosen the nut that holds the blade to the shaft. Hold on to the locking rod while turning the wrench clockwise. Remove the nut, washer and blade.
Slide the new blade onto the shaft and put the washer and nut back on. Tighten the nut counterclockwise with your 5/8-inch box wrench and make sure the blade stays flat and centered on the output shaft. The nut should be tightened a quarter to half a turn past snug.
Remove the locking rod from the hole.
