I looked into the best 21 inch mulching blades for my mower to find a good option for me. Here are some of the best 21 inch mulching blades.

Mr Mower Blades 195-005

These blades are made in the USA. They are tough and durable, as a result of their hardening. They are also thick, which helps to cut through grass and leaves. Mr Mower blades are curved to create a cyclic aerodynamic lift which is ideal for mulching. Like other mulching options, they have a low lift, which reduces their effectiveness on wet turfs.

  • Made in USA
  • Sturdy and durable
  • Good angle for mulching

Cons

  • Low lift might require more effort on certain lawns

The genuine Honda blades are exactly the same parts as stock mower blades for the Honda HRX217 mower. They are curved upwards to enhance your mower’s ability to mulch.

These blades are also austemper hardened, making them strong and durable. They are also ideal for heavy duty work, and may be used to mulch leaves as well as pine cones. The low lift on the blades makes mowing the lawn in wet conditions very difficult, and you may be required to re-do certain patches.
