Choosing Mower Blades

Not all lawnmower blades are created equal. That’s because different types of blades are better suited for specific mowing applications and turf types. Some lawnmower blades are also more suitable for use with collection systems like the Cyclone Rake. Here’s an overview of the three main types of rotary mower blades for the homeowner: standard blades (also called low-lift or medium-lift), mulching blades, and high-lift blades.

Rotary mower blades create “lift” as they rotate and cut the grass, helping move the grass out of the mower discharge chute. Standard blades, sometimes called low-lift or medium lift, are engineered to provide enough lift to move the grass out of the mower deck area. Different blade designs can extend farther out from where the blade attaches to the mower, creating blade clearance differences. The mower operator has to understand how the blade design and mower deck height work together, especially when mowing terrain that may be uneven.

High-Lift Blades

Mulching blades are designed to help return the grass clippings back to the lawn. Mulching blades usually have a more curved design and longer blade edge. The mulching blade is designed more for cutting and returning grass clippings to the lawn, rather than creating lift needed to propel the grass cuttings from the mower.

High-lift blades are designed to create more “lift” as the mower blade spins. This design is helpful when running a lawnmower with a lawn collection system like the Cyclone Rake. The difference in blade design, especially the distance at which the blade extends downward from the mower, can help create more lift for the grass clippings and yard debris that are collected.

Lawnmower manufacturers specify the types of blades that can be installed on different mower models and provide recommendations for different blades in different applications. Be sure to consult your mower manual, as well as the user manual for your Cyclone Rake collection system, when choosing a blade for each mowing application.
