Tools & Materials
Is your mower motor spinning, but it seems like the blade is spinning slowly? You could have a damaged blade insulator. The blade insulator is a plastic washer. It has ridges along two edges on each side. The ridges on one side engage against the blade and the ridges on the other engage against the metal spacer washer. The blade insulator acts as a shear pin to help protect the blade shaft and the motor if the blade were to suddenly stop (such as if it hits a large rock or a tree root). When the blade stops, the ridges on the insulator will shear off, allowing the blade to slip on the shaft. Once this occurs, the blade may slip during normal mowing. You should periodically inspect the blade insulator and replace it if you notice any damage.
Let's get started.
REMOVING THE BLADE INSULATOR 1. Remove the blade insulator.
a. Tip the mower on its side to gain access to the blade.
b. Wedge a piece of scrap wood between the blade and the mower deck to prevent the blade from rotating
c. Use a wrench to remove the nut that secures the blade.
d. Remove the spacer.
e. Remove the blade insulator.
INSTALLING THE NEW BLADE INSULATOR
2. Install the blade insulator.
a. Install the new blade insulator. (Verify that the shoulders of the new insulator align with the blade.)
b. Install the spacer.
c. Secure the blade with the nut.
