What’s the Difference between Mulching and High-Lift Blades?

Lawn mower blades are an important factor in the health and aesthetic of your lawn. If not replaced seasonally, mower blades can deliver a dull cut and leave grass weakened and prone to disease.
Before it's time to replace mower blades though, you should first determine the type you need for your specific mower. There are several blade types available - each providing different compatibility and benefits.

1) High-Lift Blade
A high-lift blade is designed with larger wind wings to increase airflow and aid in bagging grass clippings, especially on riding mowers with longer discharge tubes. High-lift blades cut grass cleanly before discharging the clippings onto the lawn or into a grass collection system, such as a bagger. High-lift blades are often referred to as 2-in-1 blades because they can be used to both discharge or bag clippings.

2) Mulching Blade for 42' and 46' Decks
Mulching blades generally have a more curved surface with two distinct cutting planes along the blade's edge. Older-style mulching mowers include two blades arranged perpendicularly to each other. When a baffle or mulch kit is installed on the mowing deck to prevent clippings from discharging, mulching blades circulate the clippings beneath the deck where they're cut and recut into tiny pieces. The finer clippings will decompose more quickly, releasing nutrients into the soil. Mulching blades may be referred to as 3-in-1 blades or all-purpose blades, as they can be used to mulch, discharge or bag clippings.

3) Xtreme Mulching Blade for 50' and 54' Decks
For a more Xtreme mulching experience, the Xtreme Mulching blade has eight cutting surfaces to cut the clippings into even smaller pieces. The medium-lift wing is turned out for more dispersion under the deck. A smaller wing is turned in to help push the grass to the center of the deck.

4) Low-Lift Sand Blade
The Low-Lift Sand blade is ideal for Southern and Coastal regions with very dry, sandy conditions. The geometry of the blade edge creates a vacuum effect to lift grass as it's cut. The sand flows over the wing profile, preventing wing wear. These blades can last up to three time longer than traditional blades.
