Types of Lawn Mower Blades
Different lawn mower blades have different uses according to their functions, which is essential to make the right choice. There are three types of lawn mower blades:
- Discharging blades: These blades discharge debris into bags or push grass away. They are most suitable for push mowers because they lift the grass to cut it down, and hence,they are also called high-lift blades.
- Mulching blades: Theseall-purpose blades, usually called three-in-one blades, havecurved and serrated edges to cut the grass into finer pieces and then pour it back to the ground. The innermost curve of the blade generates air pressure to blow out the small debris into the soil. Mulch blades also allow proper distribution of air, which is a plus.
- Gator blades: They offer medium lift and provide softer, smoother, and cleaner cuts of the grass. They are most suitable for lower-level grass.

How To Choose The Best Lawn Mower Blades?
Here are the features you must look at while purchasing a lawnmower blade:
- Width of the blade: Wide blades can cover more area and reduce the time you spend on the mower. But at the same time, a large width may damage other components of the lawnmower. The ideal width is two to three inches.
- Length of the blade: The perfect length and width provide high efficiency for the blade. For short mowers, the optimal length is 16 to 22 inches. There are also blades up to 30 inches in length.
- Blade holes: The center hole design can vary depending on the blade. A simple central hole will loosen over time and may require a washer. Five or six star holes provide a firmer grip. Before purchasing, you must also check the size of the attachment bolts in the mower. •
- Deck size: This factor largely depends on the size of the lawnmower. The smaller the deck size, the smaller should be your blade size.
- The shape of the blade: Try to purchase a replacement blade that is most similar to the original blade. Check for blades compatible with your lawnmower for the best fit.
- The number of blades: Push mowers and self-propelled lawnmowers only require single blades. Riding lawnmowers may require more than one.
- Material: Stainless steel blades have a longer service life. If the construction is too thin, the blades may bend during use. Similarly, if you plan to use a lawnmower on wet grass, consider using an anti-rust model.
