Buying Guide Image

Frequently Asked Questions (FAQs)

1. How do I know what mower blade to buy?

When purchasing mower blades, it's important to consider the length of the blade and the center hole diameter. If your mower requires outer holes, make sure to purchase a blade with the appropriate ones. For mowing cool-season grasses, high lift blades are recommended.

2. What blades are better for mowing?

High-lift blades are generally better for most mowing conditions. They are designed to discharge clippings from the deck or be captured in a bagger. On the other hand, low-lift blades are suitable for dry conditions, sandy soil, and cutting at extremely low settings.

3. Which is better mulching blade or high lift?

Mulching blades are specifically designed to chop down grass into mulch, while high lift blades are designed to eject the cut grass out of the chute or into a collection bag. High lift blades are better for cutting wet or tall grass without clogging the lawn mower.

4. How do I find out my lawn mower blade size?

To determine the size of your lawn mower blade, measure the length diagonally from one tip of the blade to the opposite tip. It's important to measure the length correctly, as measuring end to end will give you the wrong blade length.

5. What is the difference between a regular mower blade and a mulching blade?

Regular mower blades, also known as "2-in-1" or "high-lift" blades, are designed for discharging and bagging. Mulching blades have a more curved surface and often include extra cutting surfaces along the blade edges. They are specifically designed for chopping grass into mulch.

6. Is it better to use mulching blade or regular?

Using a mulching blade is preferable if you want to recirculate grass clippings efficiently and produce quality mulch for the topsoil of your lawn. Regular blades, on the other hand, are designed to lift grass cuts high and discharge them outside or into a bag.

7. Do high lift mower blades cut better?

High-lift blades are generally recommended for most mowing conditions. They are designed to discharge clippings from the deck or be captured in a bagger. However, low-lift blades are suitable for dry conditions, sandy soil, and cutting at extremely low settings.

8. What are signs of a dull mower blade?

Signs of a dull mower blade include dents or nicks in the blade, uneven grass height after cutting, grass blades looking torn instead of sliced, and brown, frayed grass edges.
