Flail Mower Vs Topper | Cutting Edge Clash

Flail Mower Vs Topper

If you’re in the world of lawn care or maintaining open spaces, you might have come across the terms “flail mower” and “topper.” These are two types of equipment designed to keep grass and vegetation in check, but they have some key differences in how they go about the job. 

In this quick guide, we’ll break down the basics of flail mowers and toppers, helping you understand their unique features and how they can make your green spaces look their best. 

Whether you’re a seasoned landscaper or just getting started with lawn maintenance, knowing the differences between these two tools can make a big difference in achieving the results you want. Let’s dive in!

How Flail Mower Works

A flail mower is a type of grass-cutting machine that uses a series of small, independently swinging blades, known as flails, to cut through vegetation. Here’s a simple explanation of how a flail mower works:


A flail mower consists of a rotating drum or shaft with attached flails. This drum is connected to a power source, such as a tractor’s power take-off (PTO).

Power Source

The flail mower is typically attached to the back of a tractor or another vehicle. The power from the tractor is transferred to the mower through the PTO, causing the drum with flails to spin.


The key components of a flail mower are the flails themselves. Flails are small, hinged blades or hammers attached to the drum. They are usually arranged in rows along the length of the drum.

Independently Swinging

Unlike traditional mower blades that are rigidly fixed, flails are attached in a way that allows them to swing freely. This swinging motion is crucial for the mower’s effectiveness.

Cutting Action

As the drum rotates, the flails swing outward due to centrifugal force. When they come into contact with grass, weeds, or other vegetation, they strike and cut through the material. The swinging action helps the flails to bounce off obstacles like rocks, reducing the risk of damage.


Flail mowers are known for their versatility. The independently moving flails can handle a variety of vegetation types, including tall grass, weeds, and even small saplings. This makes them suitable for use in different environments such as fields, orchards, and road verges.

Cutting Height Adjustment

Many flail mowers allow the operator to adjust the cutting height. This feature is useful for maintaining different levels of grass or vegetation, depending on the specific requirements of the area being mowed.

Collection or Mulching

Depending on the design of the flail mower, the cut vegetation may be collected in a bag or left on the ground as mulch. Some models also come with the option to discharge the cut material to the side.

A flail mower works by using a rotating drum with independently swinging flails to cut through various types of vegetation. Its design allows for effective cutting in diverse environments while minimizing the risk of damage from obstacles.

How Topper Works


A topper, also known as a rotary topper or pasture topper, typically consists of a horizontal rotating blade enclosed in a metal housing. Like the flail mower, it is connected to a power source, such as a tractor, through a PTO shaft.

Cutting Mechanism

The blade on a topper rotates parallel to the ground, cutting the vegetation as it spins. Toppers often have a single blade or multiple blades attached to the rotating shaft.


Toppers are commonly used for cutting grass and light vegetation in fields, pastures, and meadows. They are suitable for maintaining a uniform height of the grass and preventing it from becoming too tall or overgrown.


Toppers are well-suited for maintaining grassy areas where a finer cut is desired, such as for livestock grazing or aesthetic purposes.


Efficient for maintaining even grass height. Simple in design and easy to use. Suitable for larger, open areas with less challenging terrain.


Regular blade sharpening and housing maintenance are necessary for optimal performance.

Flail Mower Vs Topper | Know the Difference

A flail mower and a topper are both types of agricultural equipment used for cutting grass and vegetation, but they have some key differences in terms of design and functionality.

A flail mower is characterized by its heavy-duty construction and a series of small, Y-shaped blades (flails) attached to a rotating drum. This design allows the flail mower to effectively tackle thicker and tougher vegetation. 

The flails are capable of swinging freely and independently, providing a more versatile cutting action. Flail mowers are often used for shredding dense grass, weeds, and even small saplings, making them suitable for rough and overgrown areas.

On the other hand, a topper, also known as a rotary topper or simply a rotary mower, features a horizontal spinning blade mounted on a shaft. Toppers are generally designed for lighter cutting tasks in more well-maintained grassy areas. 

They are effective at providing neat and even cut-to grass and light vegetation. Toppers are commonly used for maintaining lawns, pastures, and fields where the vegetation is not overly dense.

The main distinction lies in their design and intended use. A flail mower is built for heavy-duty applications, excelling in cutting through dense and tough vegetation, while a topper is a more lightweight option suitable for regular grass maintenance in less challenging conditions. 

The choice between a flail mower and a topper depends on the specific needs of the land and the type of vegetation you aim to manage.

Advantages of Flail Mower and Topper

Flail Mower


Can handle various types of vegetation, including thick grass, weeds, and light brush. Suitable for both fine turf and rougher terrains.

Uniform Cutting

Provides a consistent and even cut across the entire mowing area. Ideal for maintaining a neat and well-groomed appearance.

Safety Features

Safer than rotary mowers as the flails are enclosed, reducing the risk of flying debris. Minimizes the chance of damage to surrounding objects or structures.

Durable Design

Robust construction with sturdy materials, ensuring durability and a longer lifespan. Able to withstand challenging conditions and heavy use.

Mulching Capability

Breaks down cut vegetation into smaller pieces, acting as a natural mulch. Helps improve soil health by returning nutrients to the ground.


High Clearance

Designed to handle tall grass and vegetation effectively. Provides ample ground clearance, reducing the risk of blockages.

Lightweight and Maneuverable

Easy to maneuver, making it suitable for areas with tight spaces or irregular terrain. Can be attached to various types of vehicles, enhancing its versatility.


Generally more affordable than some specialized mowers. Offers a practical solution for routine grass maintenance without breaking the budget.

Low Maintenance

Simple design with fewer moving parts, leading to reduced maintenance requirements. Easy to clean and service, minimizing downtime.

Quick Cutting

Efficient in quickly cutting and topping off tall grass, improving overall land aesthetics. Well-suited for large areas where speed is essential.

By considering these advantages, you can make an informed decision based on your specific mowing needs and the type of terrain you’re working with.


In the debate between flail mowers and toppers, both have their perks. Flail mowers excel in handling tougher vegetation, providing a finer cut, and handling uneven terrain. 

Meanwhile, toppers are simpler, lighter, and more suitable for maintaining shorter grass and light brush. The choice ultimately depends on your specific needs: if you’re dealing with rougher areas or thicker vegetation, a flail mower might be your best bet. 

But for lighter maintenance and more even terrains, a topper could be the more efficient choice. Always consider the terrain, vegetation type, and desired outcome before making your decision!


What is a flail mower, and how does it differ from a topper?

A flail mower is a cutting tool with small, Y-shaped blades (flails) attached to a rotating drum. It cuts vegetation with a chopping or mulching action. A topper, on the other hand, typically has large rotating blades and cuts grass more like a traditional lawn mower.

What types of terrain are suitable for a flail mower?

Flail mowers are versatile and work well on rough or uneven terrain. They can handle tall grass, weeds, and even small branches, making them suitable for areas with varied vegetation.

When should I choose a topper over a flail mower?

A topper is a good choice for maintaining well-manicured grass in fields or lawns. If you’re mainly dealing with shorter grass and want a cleaner, more traditional cut, a topper may be more suitable.

How do flail mowers and toppers differ in terms of safety?

Flail mowers are often considered safer because the flails are enclosed, reducing the risk of debris being thrown. Toppers, with exposed blades, may pose a higher risk of objects being thrown during operation.

Which is easier to maintain – a flail mower or a topper?

Flail mowers are generally easier to maintain because the individual flails are replaceable, and their enclosed design reduces the likelihood of damage. Toppers may require more attention to the condition of larger, exposed blades, which may need sharpening or replacement.
