Understanding Lawn Mower Blades
Types of Lawn Mower Blades
Lawn mower blades come in various designs, each with its purpose and advantages. Here are the three most common types:
1. Mulching Blades
Designed to finely chop grass clippings, allowing them to decompose quickly and return nutrients to the soil- Features a curved surface and multiple cutting edges, which help keep clippings circulating under the mower deck until they are cut into tiny pieces
- Ideal for homeowners who want to recycle grass clippings back into their lawn
2. Standard Blades
- Also known as straight or 2-in-1 blades
- Most common type of lawn mower blades
- Features a simple design with a single cutting edge that lifts the grass and cuts it cleanly
- Suitable for most lawn mowing tasks, including bagging or side discharge
3. High-Lift Blades
- Features a more pronounced angle on the cutting edge, creating a strong airflow that lifts the grass for a clean and even cut
- Ideal for mowers with bagging systems, as they efficiently lift and propel the clippings into the bag
- Requires more engine power, so it may not be suitable for all mowers
