Choosing the exact lawn mower that caters to your needs can be challenging. To help you make an informed decision, we've compiled detailed information on how to properly measure lawn mower blades.

The most common mistake when measuring lawn mower blades is measuring straight across the blade, which will give you an inaccurate measurement. To properly measure a lawn mower blade, you should measure diagonally. Additionally, if your mower blade has 3 holes, make sure you are measuring the center hole diameter by measuring straight across.

If your mower blade does not have a circular center hole, you will need to determine the shape and measure the distance between the centers of the two outside holes, known as the "center to center" measurement.

Most lawn mower blades have circles as the center hole shape, but there are other possible center hole types, such as squares or rectangles. Knowing the specific center hole shape of your blade is important for ensuring a proper fit.

To accurately measure the width of your lawn mower blade, make sure to measure straight across at the widest section of the blade. The width of the blade is usually not a critical factor for fitment, but it's good to know this measurement.

Blade thickness is measured by taking the distance from the top of the blade to the bottom. It is recommended to use a replacement blade with the same thickness as the original equipment manufacturer (OEM) blade on your lawn mower. If you cannot determine the OEM blade part number, a slightly different thickness shouldn't be a major issue, although using a blade that is too thick could lower the RPMs and impact cut quality.

We offer a variety of lawn mower blade types to suit different needs, including standard or medium-lift blades, low-lift blades, high-lift blades, mulching blades, and Gator blades. These blades are compatible with a wide range of Cub Cadet, MTD, Troy Bilt, and Craftsman lawn mowers.
