Types of Mower Blades
Lawn mower blades are offered in multiple styles and sizes. The blade type should be selected based on the condition of the grass and whether it will be mulched or bagged. Below are the most common blade types.
Blade | Image | Description |
Mulching |  | Lifts, cuts, and recuts grass to create a fine mulch that is returned to the soil as nutrients. Best for routine cutting. |
Gator |  | Toothed edges for multiple recuts to provide better mulching in fewer passes. Great for chopping up leaves. |
Standard |  | Medium lift for all types of cutting. Wear-resistant and durable. |
Bagging |  | Blade design to create airflow to direct clippings into a bag attached to the mower. |
Hi Lift |  | Angled edge to create hi lift for tall grass and bagging clippings. |
Laser Edge |  | Lasts up to 5 times as long as other blades with self-sharpening functionality. |
Mower Compatibility
The lawn mower blade size must be compatible with the mower. Ensuring the blade fits the mower’s make and model is essential. Using the wrong size or center hole type can lead to poor performance or mower damage. Some blades are universal, while others are model-specific.
Important measurements to consider:
Measurement: The blade size is measured diagonally lengthwise.
Hole Diameter and Spacing: The size and shape of the center hole are most important. Spacing of outside holes is sometimes considered as well.
Right- or Left-hand Cut: The location of the cutting edge can differ by model.
