How to Backlap a Cylinder Mower - Allett Kensington 20H

I show how to backlap a cylinder mower in this episode. The first thing to do is remove your cylinder cartridge and gather your supplies.

Backlap Supplies Needed

Backlapping compound and brush
Screwdrive for reel to bedknife adjustment
Drill for spinning cylinder
Safety goggle (eye protection)
Paper strips for sharpness test
24mm socket or 15/16″ socket
1/2″ socket/drill adapter
Grille apron or old t-shirt to protect clothing (if desired)
Clamps for securing cartridge to table (if desired)

First, remove your cartridge and mount securely to your table top. Gather your supplies listed above.

Second, do a paper cut test to find the areas of poor performance. Adjust the reel to bedknife, if needed.

Third, using the 24mm socket begin spinning the cylinder in a clockwise direction. As it spins, apply lapping compound up and down the cylinder. Do a paper cut test and adjust the cylinder as needed. Repeat this process until you get a nice sharp cut entirely down the reel.

Reinstall the reel cartridge and enjoy the mow!!
