If you're a beginner to purchasing lawn mower blades, it's important to understand the different types available along with their intended purpose. Generally speaking, there are three main types of lawn mower blades – regular (or 2-in-1) blades, mulching blades, and high-lift blades. Depending on your lawn mower, you may need to purchase a specific type of blade.
Regular (or 2-in-1) blades are designed to cut grass while they also collect clippings. This type of blade is suitable for most types of grasses and can be used with a bagging system, which collects the clippings on the side or back of your mower. If your mower has a discharge chute, you should avoid this type of blade as it may clog the chute.
Mulching blades are designed to cut grass into very small pieces so that it can be used as fertilizer for your lawn. While mulching blades are more efficient at cutting grass, they require more frequent blade-sharpening than regular blades. These blades are most suited for grass that's not too tall or thick.
High-lift blades are ideal for rough and overgrown grass, as they create more lift to help move clippings up and away from the blade. When using this type of blade, you should ensure that your mower's deck height is set to the lowest level possible in order to achieve the best results.
When purchasing new lawn mower blades, make sure to check the manufacturer's instructions to determine the correct size and type of blade for your mower model. You should also consider whether you want a single or double-sided blade – depending on your mowing needs – and if you need a specific brand or material.
