Lawn owners often choose reel mowers because they are easier to use and maintain than gasoline powered mowers. A reel mower will never need fuel, engine lubricant or electrical repairs. And while you must remove a gasoline-powered mower's blades and sharpen them with metal files, reel mower blades are much easier to grind sharp. All you need are a few simple tools and a sharpening kit.
Place the mower somewhere where you won't have to strain to access its blades. An ideal location is on top of a sturdy table. Then push the handle down so that the mower is lying relatively flat.
Remove the hub cover from the wheel. On almost all reel mower models, this is a small plastic cover just over the hub of the wheel. Wedge your screwdriver between the cover and the wheel and pop the cover off.
Slide off the C-ring. The C-ring is, as its name indicates, the C-shaped ring that sits just under the nut that secures the wheel. Use your flat head screw driver to push it off the nut and set it aside.
Pull the wheel off.
Pull the gear off with your hand.
Slide the short end of the crank (found in the sharpening kit) over the post that the gear was attached to.
Apply the grinding compound. In the kit you will find a small plastic container and a brush. Open the container and apply an even coat of its contents to the blades of your reel mower.
Turn the crank so that the blades turn backward. Continue to turn them until you see the smooth metal edge of the blades.
Re-assemble the mower. Remove the crank and put the gear back on. Next, pop the wheel back on and secure it with the C-ring. Then snap on the hub cover.
Clean the grinding compound off the blades with a spray cleaning solution.
