Mulching Blades vs Regular Blades – Differences + Which to Choose

Mowing is an essential part of regular maintenance required to keep the turf thick and healthy. However, knowing the difference between mulching blade vs regular blade will help to make suitable choice when choosing the best blade for your lawn.

Shape is the main difference you’ll notice when comparing the two blades. Mulching blade features more curves to increase surface areas of the cutting edge, while regular blade has practically straight cutting edge. It is designed to cut grass more efficiently.

Mulching Blades vs Regular Blades – What’s the Difference?

Mulching blade vs regular blades differs in terms of the shape, length of cutting edge, aerodynamics, discharge issues and blade functionality explained below:

Mulching BladesRegular Blades
A 3-in-1 blade that mulches, bag and discharge grass clippingsA 2-in-1 functionality, bagging and discharging grass clippings
Its aerodynamic design features a reduced lift to allow clippings in the deck for further cuttingDesigned to generate a good lift for increased air flow in the deck necessary for discharging grass clippings
Retains clippings in the deck for longer thus prone to cloggingDischarges clippings faster thus less likely to cause clogging
Has more curves for increased cutting surfaceHas a straight cutting edge
The cutting edge is relatively longerHas a short cutting edge

Shape of the Blade

Shape of the blade is the main difference between mulching blade and regular. Mulching blade contain more curves to increase cutting surface area. Mulching blade is not designed to cut grass quickly, instead it create a greater circulation clippings in the deck for further cutting.

On the other hand, regular blade is the opposite of mulching blade. The cutting edge is practically straight. It’s designed to cut grass quickly and effectively bag or discharge it out.

Length of Cutting Edge

You’ll easily notice difference between mulching blade and cutting blade by simply looking at the length of cutting edges. Mulching blade has a relatively long cutting edge. Other than curves, long cutting edge also increases the cutting surface area.

Regular blade doesn’t require a long cutting edge. It’s designed with a short cutting edge to cut and discharge clippings fast.

Aerodynamics of the Blade

Mulching blade has a reduced lift which enables it to mulch. It creates a greater cutting surface areas while allowing air flow to circulate clippings in the deck for further cutting. As a result, the mulching blade is not effective as regular blade on bagging or discharging grass clippings.

With regular blade, it generates a good lift that allow increased air flow in the deck. This is the main reason why they are considered as the best option for bagging or discharging grass clippings.

Discharge Problems

Mulching blade is designed to keep grass clippings in the deck for a bit long. The blade also has a low lift which can decrease air flow in the deck. As a result, it’s prone to clogging.

Regular blade generates more lift to increase air flow in the deck. It also discharge clippings more efficiently. Therefore, the likelihood of clogging is greatly reduced.

Functionality of the Blades

Mulching blade has 3-in-1 functionality, this means that it’s capable of mulching, bagging and discharging. It has versatility in a single blade. On the other hand, regular blade has a 2-in-1 functionality. It can only bag or discharge clippings.

How do Mulching Blades Work?

Mulching blade has an added advantage of mulching the lawn while mowing at the same time. The blade perform a magic trick of causing grass clippings to disappear within the lawn instead of bagging or discharging it out.

The secret lies in design and shape of the blade. It has a long cutting blade that features several curves to increase surface area of the cutting edge. It cut the grass and bring it into the deck where it is chopped a multiple times into fine particles that are dropped back into the lawn.

A mulching blade also features a 3-in-1 functionality. This mean that the blade can be used for mulching, bagging or discharging clippings out. For instance, if you decide not to mulch your lawn directly, you can bag the clippings and use it for compost.

However, it’s ideal for use on a lawn that receive frequent mowing. Using a mulching blade on an overgrown lawn will cause clogging. Mulching blade does not generate the same lift and power like a regular blade.

Can you use mulching blades without a mulching kit?

Yes, you can use mulching blade without a mulching kit. Mulching kit consist several accessories that are on a lawn mower to work as a mulching one. The kit contain items such as mulching baffles, mulching blades, restriction plates, defectors and decals.

Mulching blade alone is not enough to do the task. It require co-ordination of different accessories in the kit to perform mulching. For instance, a restriction plate is placed at the rear chute to deflect and block clippings from discharging through the chute.

The ultimate purpose of restriction plate is to allow the clippings to remain under the deck so as to be chopped further. When purchasing a mulching kit, it is recommended to choose accessories that are compatible to your mower. Restriction pates are not universal like mulching blades.

Mulching blades can fit on any type of lawn mower. However, be sure the blade is properly fixed in the deck. Check if the bolts are securely tightened before commencing operation.

Mulching Blade or regular – Which is better?

Choosing between a mulching or regular blade will depend on the lawn maintenance you intend to do. With mulching blade, you have an added advantage of mulching your lawn while mowing. Crass clippings contains nitrogen and other nutrients to nourish your lawn as they decompose

However, mulching blade require frequent mowing. You may be required to mow the lawn several times a week. With regular blade, you will require less frequent mowing. It is also ideal if you want to bag the grass clipping more efficiently.

Both mulching blade and regular have their own pros and cons. Let’s have a look at each of them:

Mulching Blade Pros

  1. Produces a natural fertilizer: Mulching blade chops the grass clippings into fine particles and discharge them back into the lawn as a mulch. They decompose to provide nutrients to your lawn.
  2. It’s environmentally friendly: It creates an organic fertilizer rich in nitrogen, you don’t need to use synthetic fertilizers that are harmful to environment.
  3. It has a 3-in-1 functionality: Can be used for mulching, bagging and discharging grass clippings.

Mulching Blade Cons

  1. Require frequent mowing: You will be required to mow your lawn at least once per week.
  2. Prone to clogging: It generates a low lift that is prone to clogging.

Regular Blade Pros

  1. Not prone to clogging: Regular blade generate more lift which enables it to discharge clippings more efficiently.
  2. Generates a good lift: It is designed to generate increases lift to boost air flow at the deck for effective bagging or discharging
  3. Creates a level cut: it creates a level cut with less balding areas as compared to mulching blade.

Regular Blade Cons

  1. You can’t mulch the clippings: It only has a 2-in-1 functionality. It’s only possible to bag or discharge clippings.
  2. Not ideal for sandy conditions: Regular blade creates a great vacuum when mowing. It’s great for cutting grass level but not ideal for sandy soil, it disturb soil by sucking sand particles into the deck.

Final Thoughts

Design or shape of the blade is the main distinctive feature between a mulching blade and regular. Both are ideal for mowing your lawn. However, a mulching blade is more advantageous compared to regular when you want to in cooperate the grass clippings back into lawn as a mulch.
