The backlapping tool is used on a reel mower during the sharpening process. When the blades become dull and your grass becomes harder to cut or doesn't cut as cleanly, break out the backlapping tool along with some sharpening compound to sharpen your reel mower's blades. Sharpening kits that include a backlapping tool, are often included when you purchase your reel mower or purchase a kit from a reel lawnmower retailer or dealer.

  1. 1

    Prepare the reel mower for sharpening by removing the "C" or "E" clip on the end of the blade shaft. Pry it off with a flathead screwdriver by placing it underneath the clip and pushing up on the clip. Also remove the wheel and the pinion gear underneath the wheel from the blade shaft.

  2. 2

    Position the backlapping tool over the shaft where the gear was placed.

  3. 3

    Apply the sharpening compound by painting it on. Dip the paintbrush into the compound and brush it evenly over the blade edges.

  4. 4

    Rotate the backlapping tool counterclockwise to sharpen the blades. Keep rotating the backlapping tool until the blades are smooth and sharp.
