What is a Flail Mower and What Does it Do?

A flail mower is a small mower with a rotating drum featuring multiple smaller flails (blade-like objects) attached that spin rapidly in order to deal with heavy vegetation, making them useful for land management. They are typically available in two models: walk-behind for smaller land management and tractor attachments for larger areas.

The core purpose of a flail mower as a piece of machinery is to cut through heavy vegetation and grass. Flail mowers for tractors run on the PTO, just like a topper would. They are designed to do the heavy cutting that a regular lawn mower may not be capable of, unlike a flail topper, which is, as the name suggests, just the top. 

Who is a Flail Mower For?

Flail mowers are for people who need a reliable way to deal with vegetation that is considerably overgrown, to such a point where a regular topper or lawn mower would not be able to cut through. It is worth considering a flail mower as a heavy-duty lawn mower, ideal for dealing with long grass and bushes. Many use them to level pastures. 

If you have a decently sized piece of land that you wish to change the purpose of, i.e. turn it into land for farming produce, you may need a flail mower to transform it to a condition where the first steps of food production can begin.

What Can a Flail Mower Cut?

What makes a flail mower so popular is its versatility and range of things it can power through, making clearing land that much easier. It is important to remember these machines are designed to cut through vegetation, and not to be used for smaller tasks such as grass cutting, which could be done by a conventional mower.

A flail mower can cut through:

  • Tall grass 
  • Thick weeds 
  • Brush and bushes 
  • Small trees in some cases

What Size Flail Mower Do You Need?

The required size of a flail mower depends on the size of your land and the tasks for which the mower will be needed. For areas of dense and heavy vegetation, you’re more likely to need a heavy-duty machine capable of making light work of heavy vegetation. For smallholdings with less vegetation but still a need for a flail, we would suggest a compact flail, as these provide more than enough power to complete your desired task.

How Do Flail Mowers Work?

They are very simple, yet effective machines. Flail mowers use the power of rotating hammers at high speed to finely cut and mulch organic matter. It is the use of rotating hammers that gives them enough power to blast through mulch and dense vegetation with ease. It is worth noting that, unlike a traditional lawn mower, a flail mower does not store any of the grass or vegetation it cuts, leaving you with the decision of whether to collect it and deposit it in some sort of compost or not. 


Flail mowers can be broken down into two different types, serving different purposes. They therefore work slightly differently from each other, but the theory is the same across the board.

What Types of Flail Mowers Are There?

There are two different types of blades used in flail mowers, T hammers and Y hammers. Each one is shaped like its letter denomination, giving the mower different characteristics. T hammers are good for all types of cutting, including through shrubbery and hedges. Y hammers are suited to jobs that require a large amount of mulching, such as lawns and brambles.

Flail mowers typically are either push-along mowers or tractor-mounted PTO. The first is great for smaller areas that require high precision, but it will struggle to cover a decent area if used in a field. Tractor-mounted PTO flail mowers are the most popular choice as they come with a whole host of benefits that make them easy to use, efficient and time-saving.
