Reel mowers are commonly used on lawns that need to be mowed close, like Bermuda grass. Reel mowers work by using the same mechanism that scissors use to cut items---two blades meet at an angle to shear the grass off at a uniform height. Over time, the blades will dull and you will notice more resistance when mowing, along with a less-even cut. To keep your lawn looking healthy and well-groomed you must sharpen your reel mower blade when it becomes dull.
Lay your reel mower down on either side to gain access to a wheel side. Look for a plastic cover on the side of the wheel.
Lift off the plastic cover by prying it up with your flat-head screwdriver.
Pry off the metal "C" ring that holds the wheel on to the reel mower. Remove the wheel and the metal gear that is found under the wheel.
Place the metal crank that came with your sharpening kit over the shaft that the gear was on.
Take the paint brush that came with the kit and dip it into the sharpening compound. Brush sharpening compound onto each blade of the reel.
Turn the crank so that the reel moves backwards. Keep cranking until each blade on the reel gets a shiny, smooth metal edge.
Remove the crank and place the gear back on the shaft. Place the wheel back on and push the "C" clip on to hold the wheel in place. Snap the plastic cover back on the wheel.
