Blade Removal

Tip of the Moment; 1/29/00

Removing a cutting blade from a rotory mower to sharpen or replace it can be difficult without an air power wrench. If you have a pair of vise grips or some other clamping device that is stout, clamp it to the bottom of the deck so it acts as a blade stop.

Remember, when working around the blade, remove the spark plug for safety reasons and tip the mower spark plug hole straight up. Don't turn the mower upside down.

Check the owners manual for proper torque when retightening the blade. If not available, it has to be very tight, this is important. If you hear a knocking when you start the mower, shut it off immediatly and tighten the blade more. A loose blade can shear the flywheel key, not to mention come flying out to get ya. Use a socket or wrench that is in good shape and preferably a 6 point to avoid slipping. Wearing a pair of gloves for protection is a good idea as well.
