Here are some key facts about blades:
Core functions:
Cuts grass blades: The sharp blades that rotate at high speeds cut grass stems.
Creates airflow: The shape and rotation of the blades create an updraft that makes the grass stand upright for a clean cut and blows the clippings into a bag or evenly spreads them on the lawn (if mulching or side discharge mode is selected).
Main types:
Standard straight edge blades: The most common and most economical type. Has a straight or slightly curved blade edge that provides a clean cut. Usually used to mow and maintain lawns in good condition.
High lift/fan blades: Blades designed with a more pronounced curvature or wing-like structure that can create a stronger updraft. Advantages: More efficient blowing of grass clippings into a bag, or more uniform mulching (grass clippings are cut multiple times and blown back onto the lawn). Disadvantages: Higher engine load when working on dense or wet grass.
Mulching blades: Blades designed specifically for mulching (often also high-lift designs). Characterized by longer blades, sometimes with extra fins or special shapes, the goal is to more finely cut grass clippings multiple times and then evenly spread them back on the lawn as a natural fertilizer.
Low-lift blades: Produce a weaker airflow. Mainly used to deal with heavy, wet or long grass, because the strong airflow may flatten wet grass instead of blowing it up. Also commonly used on mowers with a "grass mulcher" attachment.
Multi-purpose blades: Blade designs that combine standard cutting and mulching functions, trying to strike a balance between grass collection, mulching and side discharge.
Reinforced/heavy-duty blades: Made of thicker steel, more durable and more impact-resistant. Suitable for lawns with a few small branches, stones or uneven terrain. Usually more expensive.
3-in-1/2-in-1 blades: Claim to optimize grass collection, mulching, and side discharge simultaneously through special designs (such as additional cutting edges or wings).
