How To Choose A Brush Cutter Blade?

What To Look For When Buying A Brush Cutter Blade?

The best way is to buy the blades that are designed specifically for your type of mower.

The most common types of blade you will find on these machines are either straight or curved, and they can be found in different sizes.

You want something with enough width so it won't get caught up between the deck rollers as well as being long enough to reach all areas of grass without having too much overlap.

You also need a blade that has some sort of cutting diameter blade edge on one side which allows the blade to cut through the grass more efficiently than if there was no sharpening at all.

What Are the Types of Brush Cutter Blades?

There are two main categories: Straight & Curved.

Straight blades have an even thickness throughout their length while curved blades taper from thickest point towards thinner end.

Curved blades tend to work better when used on larger lawns because they allow them to cover more ground per pass.

How Do I Know Which Type Of Blade Is Best For My Lawn Mower?

It's important to know what kind of blade works best for your particular garden machine before buying any brush cutter blades including brush cutter head.

You should always check out reviews online first to see how other people feel about each brand.

If you're looking for a specific size then make sure you look into the dimensions of the blade.

If you don't know exactly what size you need then just go ahead and order whatever fits inside the opening of your mower.

Features and uses of a brush cutter

Brush cutter blades come in many shapes and sizes but here we'll focus on those that are commonly available today.

They range anywhere from 6 inches wide to over 20 inches depending on the model.

Most models use a single-sided blade where only one side has an horizontal cutting edge.

This means that the opposite side doesn’t have anything to help guide the blade along the surface of the dense weeds.

Some newer designs feature double sided blades where both sides have edges.

This makes it easier to trim around trees and shrubs.

A few brands offer triple edged brushes where three separate edges exist on the same blade.

These are usually made for large commercial applications like golf courses.

Types of Brushes Cutters

Here are the basic types of brushcutter blades:

  • Single Sided - Single sided blades are typically used by homeowners who prefer not to spend extra money on multiple blades. They do however provide good coverage across the entire area of the lawn.
  • Double Sided - Double sided blades are often preferred by professional landscapers due to their ability to easily navigate around obstacles such as bushes and trees.
  • Triple Edged - Triple edged blades are generally used by professionals who require greater precision during operation. Their increased number of edges helps ensure that the blunt blade diameter cuts evenly across the turf.

Accessories and attachments for brush cutters

The most common type of accessories include:

  • Lawn edger - A tool with a rotating head that is design efficiency to be attached to the front or back of a brush cutter. It can either be powered manually or via electricity.

The purpose of this blade accessory is to remove excess soil, rocks, etc. from the lawn so that it looks neat and tidy.

  • Fertilizer spreader - This attachment spreads fertilizer onto the lawn using pressurized air.

Some fertilizers contain chemicals which may harm plants if sprayed directly onto foliage.

By spreading the fertilizer through an aerator, these harmful substances will stay away from the plant leaves.

  • Mulching tools - There are several different kinds of mulch tools including hand held versions, rollers, and even electric ones.

Handheld versions are great for small areas while roller type devices are ideal for covering large expanses. Electric versions work well when there's a loss of power source nearby.

Are brush cutter blades universal?

Yes, most brush cutter blades can be used with almost every type of lawnmower.

However, certain features may vary slightly between different manufacturers so it is recommended that you read up on the specifications of the compact product you want to buy.

For example, some commercial machine will accept blades wider than 8 inches whereas others won't, this is the advantage with blades.

Also, some models will accept blades longer than 12 inches whereas others won't.  

Metal blade vs plastic blade

There are two main categories of blades; metal or plastic.

The difference lies in the material itself.

Metal blade are stronger and last much longer than plastic ones.

Plastic blades also cost less which is why they are popular among consumers.

But if you plan on using your brush cutters regularly then you might find yourself replacing these metal brush cutter blade quite frequently.

So unless you really enjoy spending time sharpening them, stick with metal blades. 

Chisel blade vs straight blade

Another important factor when choosing a brush cutter blade is whether it's chisel type blade, shaped or straight.

Chisel blade type tend to work better at removing weeds while straight blades perform best at clearing debris.

However, this isn't always true because each brand uses its own unique design.

So make sure you check out all the specs before buying.

Mulching blades

These are designed specifically blade for mulching purposes.

They're ideal for creating small piles of organic matter that decompose over time.

You'll need to purchase an attachment kit from your local hardware store to attach these blades onto your mowers.

In addition, there are many attachments available online that allow you to use your existing mowing equipment.

Brush destructor blade

This kinds of blades has been specially developed to destroy grass blade clippings without damaging other lighter vegetation.

It works by cutting off the top layer of grass blade leaving only the roots behind.

As such, it requires more maintenance but it does save you money as you don't have to pay for new grass seeds.

If you live in a dry climate where water conservation is essential, then this could be a good option for you.

Cheap blades vs expensive blades

The cheap blade is the one that you can get for £10 or less.

The more expensive ones are usually made of stainless steel and have a higher carbon content, which makes them harder to sharpen but also lasts longer.

You will need to use an honing guide with your sharpening stone if you want to keep it in good shape.

If you have limited budget but still wish to get quality products, then you should consider purchasing cheap brushes instead of high-end brands.

This way, you don't spend too much money yet still receive good results.

It's not advisable though as you could end up damaging your powerful machine by cutting into it.

Chain blades vs belt blades

Belt blades are often used in commercial applications due to their durability.

They come in different sizes depending on how big your lawn is.

On the other hand, chain link blades are cheaper and easier to maintain.

You just need to replace the links every few months.

Both types of blades require regular oiling so make sure you do this properly.

What Size Brush Cutter Blades Should You Buy?

The length of the blade depends entirely upon the width of the lawn being cut.

Generally speaking, if you plan to cut an average sized yard then you would probably want to get something closer to 10 or 11 inches long.

Anything shorter tends to leave too much room between the blade and the denser weeds which could lead to unevenness in the finished result.

On the other hand, if you plan to mow down a very thick patch of woody weeds then you might consider getting a larger blade.

You should also keep in mind that thicker and highly durable blades tend to take couple of time to cut through the field of weeds because they push harder against the ground.

So if you're planning on using this modern power garden tool frequently then you might want to opt for a thinner blade instead. 

How do you install a brush cutter blade?

Brush cutter blades come pre-assembled but there's no need to worry about them falling off while you're decent operating time on your powerful machine.

Here are the procedure to install brush cutter blade:

  1. Remove the old blade from the spindle.
  2. Insert the new one into the spindle.
  3. Tighten the screws until the blade is securely attached.
  4. Accordingly tighten all four bolts at once.
  5. Replace the cover plate over the top of the spindle.

All in all, installing a brush cutter blade shouldn’t take any longer than 5 minutes.

Can I use my existing brush cutter blade?

If you already own a types of brush cutter blade then yes, you can certainly reuse it.

However, make sure that you don’t try to attach it directly onto the spindle.

Instead, remove the old blade first before installing the new one.

This way you'll avoid the risk of damage either the steel blade or the spindle.

Is it safe to operate a brush cutter without wearing gloves?

It really doesn't matter whether you wear gloves when cutting grass with a brush cutter.

In fact, many people prefer not to wear gloves since they feel like they slow them down.

But even though you don't have to wear gloves, it still makes sense to protect yourself from possible injuries caused by sharp edge objects.

That said, we recommend that you always wear safety goggles whenever working with power tools to have an effective cutting performance.

What is the best petrol brush cutter?

There isn't just one single industrial model that works better than another. It depends entirely on what kind of work you expect to get done.

Some basic entry level model will perform well under certain conditions whereas others excel under different circumstances.

The same applies to brushes themselves. Some brands offer superior performance compared to their competitors.

Ultimately, it comes down to personal preference.

You know your needs better than anyone else so you should choose whichever brand suits you best.

Is 25cc enough for a brush cutter?

A good rule of thumb is that you should never run out of gas unless you've been running the powerful engine for hours straight.

And as far as fuel consumption goes, most brush cutter engine speed only consume around 1 liter per hour.

As such, you should be able to last anywhere from 4 to 6 hours depending on how often you use your brush cutter.

Of course, these figures aren't set in stone. They depend largely on the type of grass you intend to cut.

For example, some types of grass require less pressure than others so you may find that you need to adjust the settings accordingly.

What kind of battery does a brush cutter use?

Most brush cutter batteries are rechargeable NiMH cells.

They usually hold up well under heavy usage and will provide years of service.

The best thing about brush cutter batteries is that they allow you to charge couple of times during their lifespan.

You just plug them into an AC outlet and let them sit overnight.

The next day, you simply unplug them and continue charging them again.

When fully charged, brush cutter batteries typically offer between 12 and 15 volts DC which means that you can easily connect them to other devices.

Cordless brush cutter

If you're looking at buying a brush cutter then there's no doubt that cordless models are more convenient than their corded counterparts.

However, if you want something that offers maximum efficiency and versatility then you might consider getting a corded version instead.

Pros and Cons of brush cutter blades

The two main factors that determine which is the correct model will perform better include its size and weight.

Smaller models usually weigh less and therefore won't cause too much strain on your back.

Meanwhile, heavier ones offer greater stability and strength.

When choosing between different brands, look for those that feature an ergonomic handle design of blade.

This allows steel blade capability to hold the device comfortably throughout long periods of operation.

Some models will perform well during light duty operations whereas others excel under heavy loads.

The same applies to their performance and durability.

Some models simply won't stand up to rough usage whereas others will hold up much better.

In short, there's no perfect solution here.

It all boils down to personal preferences. You'll have to try several before settling on one.
