Mower blades can often be a confusing term as there are many types and many popular terms for them. You often hear terms like 3 in 1 or high lift when trying to describe a lawn mower blade. We are here to clear up some terms and then help you find the best 21 inch mulching blade on the market for your needs.

Any way to put it, there are generally two major types of mowing blades. You have standard mowing blades, which are often referred to as 2 in 1 or high lift blades. These blades are designed to cut grass and perform simple lawn tasks. Then you have mulching blades, which are often called 3 in 1 or all purpose blades, as they are designed for mulching, discharging and bagging. These mulching blades have a more curved style and frequently include extra cutting surfaces along the blade edges.

There are definitely pros and cons to both 2 in 1 blades and mulching blades. Because mulching blades recirculating airflow better, they are less efficient at discharging grass clippings than standard mowing blades. So with mulching blades, you may experience some less than desirable cutting or discharging performance.

With mulching blades, you can install a mulch kit or baffle on the mowing deck, and circulate clippings beneath the deck and recut them into finer pieces. These finer pieces will tend to decompose quicker and release nutrients into the soil faster.
