A Scotts classic reel mower has five rotating blades that cut the grass by shearing it off between these blades and the bedknife. A reel mower works in almost the same fashion as how scissors operate. This act of shearing the grass is the best way to cut it because it makes a very clean cut which is able to rapidly seal itself to prevent disease from entering the grass. Over time, the blades of the reel mower slowly become dull and need to be sharpened. With a little practice, you will find this is fairly easy to do.
Turn the Scotts reel mower on its side. Insert a screwdriver under the side cover on the wheel and apply upward pressure to pop it off.
Pry off the "C" ring that holds the wheel in place with a flat-head screwdriver. Pull the wheel off and set aside.
Remove the gear that sits inside the wheel. It will pull right off.
Slide the crank that came with the sharpening kit over the shaft that the gear was on.
Dab the paint brush that came with the sharpening kit in the sharpening compound and brush some compound on each of the five reel blades.
Crank the handle to turn the blades backward. Keep cranking until you see a smooth metal edge on all the blades.
Remove the crank and put the gear back on the shaft. Place the wheel back over the gear and shaft and push the "C" ring back into place to hold the wheel on. Snap the plastic cover back on the wheel.
