Finding the right mower blade can be challenging. The problem with purchasing replacement lawn mower blades online is they all look the same. Not being able to pick up the new blade and compare it the old blade can be frustrating. That’s why we try to take the guess work out of buying replacement blades. Need a new blade? Or three? Start here:

Original Equipment Manufacturer Number. The easiest way to find replacement lawn mower blades is with the OEM number. The OEM number is the numerical part number of the blade assigned by the manufacturer. In most cases, just typing this number with the manufacturer name into a search engine or online store will be enough to bring up some promising results. Don’t have the OEM number? Not to worry, it is easy to find. Check the manual that came with the mower.

Model Name and/or Number. Don’t have the OEM number or a manual? Manuals for most newer mowers can be found on the manufacturer’s website. Searching for the mower manufacturer and model number is an easy way to find the needed information.

Length and Center Hole. Without an OEM number, manufacturer name, or model number, it can be difficult, but not impossible, to find the right replacement lawn mower blade. There are two blade characteristics to look at: blade length and center hole design.

The blade length should be measured diagonally from the opposite tip on each side. A blade that is too long will not fit under the deck while a blade that is too short will leave grass uncut. Finding the right blade length is very important.

The center hole is how the blade attaches to the spindle assembly under the mowing deck. There are several different types of center hole designs, including circle in various sizes, rounded rectangle, H-pattern, Y-pattern, and 5-point, 6-point, or 7-point star pattern. With the exact blade length and the correct center-hole pattern or size, it will be easy to identify the correct replacement lawn mower blade.
