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.

The blades are also perfect for heavy-duty and light-duty jobs because they are well-built and durable. However, the blades can bend on sides and fail to perform optimally when put up against rocks and hard soil.

One thing you should note is that the blades can be shipped when they are not balanced properly. This tends to create immense vibrations when you are using the mower. This can affect your grip on the mower and make it difficult for you to cut the grass properly.
