What to Consider When Buying the Best Mulching Blades

New landscapers are not familiar with mulching blades and their functionality. They usually end up buying the wrong blade, incompatible with their mower. Therefore, it is important to know the key factors before shopping for a mulch blade.

Compatibility – It is pointless if you have the best mulching blade but it does not fit your mower. Therefore, it is important to figure out what kind of blade would work for your mower. Make sure to read the manual to know important information about the mower blade specifications.

In addition, the center hole design of the blade would tell you a lot about its compatibility. Further, there are plenty of blades that provide universal compatibility. These blades can fit nearly all mower models and eliminate the need to go through the user manual for the replacement number. Different hole designs are five-star, six-star, seven star, bow-tie and s-shape shown in the picture below:

all types of designs of central holes of mulching blades shown in the picture

Durability – After compatibility, the next thing to consider is durability. Durable and sturdy models last many seasons without the need for maintenance and replacement. Make sure it is not prone to bending or breaking when bumped into a stone.

Blades made from superior quality material like metal would be fit for longer wear. Some blades go through a heat-treated manufacturing process to enhance durability.

Length & Thickness – The size of the blade is a primary consideration that most buyers overlook. The length of the mower deck should be the same as the blade, for instance, a 21″ blade would work for a 21″ mower. A longer blade would not fit while installing a shorter blade results in reduced cutting area.

Installing an inappropriate-sized blade also affects the mulching and bagging capabilities of the blade. Additionally, check the thickness of the blade to determine its quality.

Generally, thicker blades have a longer lifespan. However, too-thick blades would be heavier which slows down the mower’s speed and requires more vibrations.

Price – While every landscaper wants the best mulching blade available in the market, the budget may not allow it. Getting a premium blade is not always the right choice. Consider your property’s foliage, mower model, and other essential requirements before buying a mulch blade. With so many options available, you can get a quality tool at an affordable price.
