Choosing The Best Blades For Your Lawn Mower

Posted on: 25 May 2016


If your lawn mower is simply not cutting your grass as cleanly as it should any longer, then it may be time to opt for new mower blades. Mower blades are made from high-carbon steel that makes them hard and durable. Mower blades can be sharpened every few months so they cut better. However, the blades can bend, warp, and become nicked after several years of use. It is wise to purchase a new blade when you start to see noticeable wear. Most mower blades cost less than $50 at most, so replacement is relatively cheap. If you purchase a new mower blade, then you will have two different options available to you. Keep reading to learn about them to figure out which is best for your lawn. 

Lifting Blades

Lifting lawn mower blades are typically called standard blades, and they are the common or all-purpose blades installed on most lawn mowers. These blades are slightly curved on one side and flat on the other. The flat part of the blade is the sharp cutting surface. When the mower blade spins, the curved edge moves air up and away from the blade. This helps to pull up the grass so the flat part of the blade can cut it. This helps to cut grass efficiently and quickly. This means that this standard blade is a great choice if you like to cut your grass in a timely manner. However, you should keep in mind that the grass will be cut in longer pieces. This can cause grass to clump up on the lawn after it is cut. If you like to rake after mowing or if you use a collection bag, then this should not be an issue.

Also, lifting blades work best when used on lawns with fine or medium textured grass. Bermudagrass, fine fescue, and ryegrass are a few examples of these types of grass. The common lifting blade will cut the grass when a few inches need to be removed. If you like to cut your grass less often and need the mower blade to work through more substantial growth, then make sure to purchase a high lift blade. These blades are angled more on the sides, and this helps to increase air flow to pull up longer pieces of grass. The increase in air flow also assists with the movement of cut grass into attached bags. If you often cut grass when it is damp or if you find that the grass chute clogs easily, then this will help to eliminate clogging issues. 

Mulching Blades

If you do not collect grass in a bag and if you do not like raking after you mow, then it is wise to opt for a mulching blade instead of a lifting one. These blades have several curved metal teeth and a number of different cutting surfaces. The curved part of the blade lifts the grass so it can be cut, but it keeps the grass underneath the blade. This allows the grass to be cut several times so small pieces are left behind. The grass can then easily fall to the ground instead of sitting on top of the newly cut grass.

Mulching blades are also a good choice if you have grass with thick and dense leaves like centipedegrass, bluegrass, or .zoysiagrass If you do utilize a mulching blade, then try to cut grass only when it is dry. Otherwise, the grass will clump up around the blades and mower deck. This can cause issues with the mulching process and leave some grass uncut along the lawn. Also, since mulching blades need to cut the grass multiple times, then you will need to mow your lawn a bit slower. Also, the blades can become dull quicker than lifting varieties, so make sure to inspect the blades often and invest in regular sharpening.
