Measuring a Lawn Mower Blade


CHOOSING A REPLACEMENT LAWNMOWER BLADE

When trying to find a replacement blade for your lawn mower, the most accurate way would be to match the numbers that are stamped on the blade. Normally these numbers are near the center hole(s) on the blade.

Due to grass and debris that are usually on the blade, it is necessary to use an emery cloth to find the stamped numbers. Once in a while, however, the number is simply is not stamped on the blade, or perhaps the OEM (Original Equipment Manufacturer) blade is no longer available. If that is the case, it is possible to find a replacement by measuring your blade.

Here are the measurements you will need to find your replacement blade.
