Blade Type

The type of blade used in a lawn mower significantly influences the cutting style and overall performance of the machine. There are two main types of blades: rotary blades and reel blades, each with its unique characteristics and applications.

  • Rotary Blades:

    Rotary blades are the most common type used in lawn mowers. They spin rapidly, creating a suction that lifts the grass blades before cutting them. Rotary blades provide a versatile cutting style, suitable for most grass types and conditions. They are also relatively inexpensive and easy to maintain.

  • Reel Blades:

    Reel blades operate on a different principle. They consist of multiple blades that rotate in a cylindrical formation, scissor-cutting the grass between them. Reel blades provide a more precise and cleaner cut, resulting in a healthier lawn with fewer torn or ragged grass blades. They are particularly effective for fine-textured grasses and formal lawns where a manicured appearance is desired.

The choice between rotary and reel blades depends on the specific requirements of the lawn and the user’s preferences. Rotary blades offer versatility, affordability, and ease of maintenance, while reel blades provide a superior cut quality and are ideal for formal lawns and fine-textured grasses.
