Blade specifications: - Length: 21 inches - Width: 2 1/4 inches - Thickness: 0.1495 inches - Center Hole: Circle - Blade Type: Mulching Blade

The package includes 2 replacement blades. Please double-check your blade part number and spindle pattern before placing your order to ensure a proper fit.

Mulching blades excel at cutting tall grass and weeds, making them a great choice for handling dense mowing conditions. However, they may not perform as well in excessively wet conditions.

Low-lift blades are primarily used for side discharge and perform well in sandy conditions, producing the lowest amount of dust and noise.

Medium-lift blades are the best all-in-one solution, as they can handle bagging, mulching, and discharging, and their lift profile closely matches the original blade that came with the mower.

High-lift blades are effective at bagging or dispersing grass clippings at a distance, and they work well in thick grass. However, they require higher horsepower and are not suitable for loose or sandy soil.

Remember to always refer to your mower's manual and the manufacturer's website "parts" section, using the model number to ensure you find the correct replacement blades. This will help you choose the right blade type and size for your specific lawn mower.
