Best Overall Lawn Mower Blades for Thick Grass: Honda 72531-VH7-000 + 72511-VH7-000

The Honda 72531-VH7-000+72511-VH7-000 blades can only work with Honda products. The blades are genuine since they resemble the blades installed originally in the lawn mower. They measure 20.75 inches long and are designed to fit the HRX217 Honda mowers.

The good thing about these blades is that they rarely chip throughout their occasional use. Like most other blades, you should sharpen them first before putting them to use. Sanding them is also recommended to balance them.

These blades produce fewer vibrations and can slice through thick grass without the grass getting stuck in between them. One issue with these blades is that they sometimes arrive when they are dull. However, this is not a big issue because after sharpening them, they can last for a long period.

Another problem is that it takes longer to install the blades on your lawn mower. The setup process is not easy while the provided instructions are not clear. Additionally, the blades are not designed to mulch. Therefore, the mower uses bagging to function properly.

However, they neatly toss grass clippings into the disposal bag that is located at the rear of the mower. These are high to medium-lift blades.
