But do you really know what it is and how it can transform your outdoor tasks? 

In this insightful blog, we delve deep into the heart of this versatile machine, answering the fundamental question that has piqued the curiosity of many: What is a Flail Mower?

What is a Flail Mower?

flail mower is a versatile piece of powered garden and agricultural equipment. Unlike regular lawnmowers, flail mowers are designed to cope with challenging terrain, including rough grass, long grass, and stubborn brambles. 

They are often attached to tractors using three-point hitches, making them suitable for large-scale operations.

How Does Flail Mower Work?

The key component of a flail mower is its rotating horizontal drum, also known as the rotor. This drum is equipped with rows of flails, which can be referred to as knives, blades, or hammers. These flails are strategically staggered to ensure a continuous and efficient cut while reducing wear and tear on the machine.

A gearbox is used to create a right-angle alignment to transfer rotational energy from the tractor’s power take-off (PTO) driveshaft to the drum. 

As the drum spins, centrifugal force propels the flails outward, allowing them to deal with overgrown vegetation effectively. 

The unique design of flail mower flails, often shaped like extruded “T” or “Y,” ensures a thorough and smooth finish cut, making them ideal for areas where a neat appearance is essential.

One remarkable feature of flail mowers is their ability to handle immovable objects with ease. 

When a flail strikes an obstacle, it simply bounces off without causing damage or launching the object out of the mower deck, which is a common issue with other rotary-type mowers. It makes flail mowers particularly well-suited for areas where thrown objects could pose a risk.
