High Lift Blades Vs. Mulching Blades: What You Should Know

Team TheGrow

Lawn maintenance is an essential part of any home’s upkeep. With various options on the market, it can be difficult to decide which blades are right for your lawn.

The main difference between mulching blades and high-lift blades is their design and purpose. Mulching blades are curved with additional cutting edges, creating a suction effect to mulch and distribute grass clippings. High lift blades have a flat shape with a higher cutting angle, creating strong airflow to lift and throw grass clippings for bagging or side-discharging. Mulching blades are best for distributing clippings, while high lift blades are ideal for bagging or side-discharging thick or wet grass. The choice depends on desired outcomes and grass condition.

High lift and mulching blades are popular choices, but which is better? In this article, we’ll compare high-lift blades vs. mulching blades and explain all you need to know about them.

Whether you’re an experienced gardener or new to the game, this article will give you all the information you need to make an informed decision about your mower blade.

High-Lift Blades Explained

High lift blades are designed to lift grass and debris up and out of the way, allowing for a clean cut. They are often used with a mulching blade to provide superior mulching capabilities.

On the other hand, Mulching blades are designed to chop grass and debris into smaller pieces, which can be left on the ground to decompose.

Mulching Blades Explained

Mulching blades are designed for chopping grass clippings into smaller pieces so they can be easily broken down and used as fertilizer for your lawn.

The Benefits Of High-Lift Blades

High-lift blades offer several advantages for your lawn mower. If you want to get the most out of your lawn mower, you may wonder if high-lift blades are worth the investment.

  2. In addition, they can also make it easier to bag clippings and leaves, as well as reduce scalping on uneven terrain. 
  3. As a result of the high airflow that the high lift blades provide, it generally prevents clogging of leaves when moving wet and tall grasses.

The Benefits Of Mulching Blades

Below are the benefits of mulching blades; 

  1. It would be best to consider mulching blades to improve your lawn’s health and appearance.

Differences Between Mulching Blades And High-Lift Blades

The main difference between these two is seen in their functionality and appearance. Mulching blades are designed to create fine, consistent mulch. This is accomplished by having more cutting surfaces and a smaller overall blade.

This design also allows the blade to stay sharp longer. However, High lift blades have fewer cutting surfaces and are larger overall. Mulching blades are designed for chopping grass clippings and debris into smaller pieces to be recycled back into your lawn.

On the other hand, high lift blades are designed to lift grass clippings and debris up and out of the way so that your lawn mower can cut through it easily. 

How To Choose The Right Blade For Your Lawn Mower

If you’re unsure which blade is right for your lawn mower, it’s important to know the difference between high-lift blades and mulching blades. Understanding their differences helps you to augment them with their needs and, ultimately, helps you to decide which is best for you. 

If you have a lot of leaves and other debris in your yard, then a high-lift blade may be the better choice. However, a mulching blade may be the better option if you’re primarily concerned with keeping your lawn healthy and green.

Of course, you don’t have to choose just one type of blade – many lawnmowers come with both high lift blades and mulching blades so you can use whichever is best for the task. 

Frequently Asked Questions

When Should I Use A High-Lift Blade?

If you have a lot of leaves and other debris to collect, a high-lift blade will help you do the job more quickly. The higher blade position helps lift more material onto the mower’s deck, so you can mulch or bag it more efficiently.

When Should I Use A Mulching Blade?

Mulching blades are specially designed for chopping up leaves and grass into small pieces, which can be used as mulch for your garden. Mulching blades have a curved design that helps lift the grass and leaves into the blade so they can be cut more easily. So, when should you use a mulching blade? If you want to mulch your leaves and grass, use a mulching blade.

Can I Switch Between A High Lift And A Mulching Blade On My Mower At The Same Time?

If you have a mower with both high lift and mulching blades, you can switch between the two types of blades at any time. There is no need to remove one blade type before installing the other. Simply change the position of the blade lever on the mower deck to engage either the high lift or mulching blade.

How Do I Properly Install A New Blade On My Mower?

If you’re installing a new blade on your mower, there are a few things you need to keep in mind. They are as follows; 

  • First, ensure the blade is the right size and style for your mower.

  • Finally, be careful when handling the blade, as they can be quite sharp.

Here Are Detailed Instructions For Installing A New Blade On Your Mower:

  1. Park your mower on a level surface and turn it off. Remove the key from the ignition to prevent accidental starting. 
  2. Raise the deck of the mower so you can easily access the blade. Depending on your model of mower, this may involve removing a deck height adjustment lever or knob or disengaging a deck lift lever. 
  3. Remove the old blade by unscrewing the bolts that hold it in place. Be careful when handling the old blade, as it may be sharp. 
  4. Install the new blade in the reverse order – screw in the new bolts to secure it. Again, be careful when handling the new blade, as it may be sharp. 
  5. Lower the deck back down and re-engage any levers or knobs removed in step 2.

Final Thoughts

When it comes to choosing the right lawn mower blade, there are a few things you need to take into consideration.

Differences between the two blades are a major thing to consider as this helps you know the right one. High lift blades are great for cutting tall grass and making a clean cut.
