A flail mower is something quite different from a regular mower. A traditional mower cuts the grass where it grows, but flail mowers till the ground. The spinning blades of the flail cut the topsoil and displace it, acting as a form of fertilizer.

A Flail mower is actually pretty unique as far as lawnmowers go. They are especially popular in places where grass grows densely and there isn’t much terrain variation to work with.

So what is it that makes it so different from other kinds of lawnmowers? Here we will explain how a flail mower works and give you all the information about a flail mower.

What is a flail mower?

A flail mower is a piece of machinery with a heavy flywheel at the rear powered by a diesel engine. The flywheel is connected to blades mounted on long arms extending either side of the rear axle. As the flywheel spins, the blades whip back and forth in a scything motion to cut the grass.

The flail mower is not a new invention, having been used to mow grass in both the UK and the US in the 1940s.

Its design is based on the scythe, which was used to cut grass in fields for centuries before the invention of the first lawn mower.

There are a lot of uses for these machines, but the primary use is for farm use.

How Does Flail Mower Work? – Everything You Need to Know

How Does Flail Mower Work?

The flail mower works similarly to the rotary mower, except that the blades are flailing in a scything motion. The blades are connected to a heavy flywheel at the machine’s rear by long arms extending either side of the rear axle.

As the flywheel spins, centrifugal force causes the blades to whip back and forth in a scything motion that cuts the grass.

The flail mower is used primarily on rough terrain. It can be beneficial in areas too steep or too uneven for a rotary mower, such as woodland or meadows. It is generally more expensive than a rotary mower and is also heavier.

However, it can often mow faster due to the greater centrifugal force of the rotating blades.

What’s the Advantage of Flail Mower?

If you’re looking for a way to finish your lawn mowing job, flail mowers are the best option. Some of the benefits of using a flail mower include the following:

  • Flail mowers are available in various widths:

Flail mowers are available in various widths, from 10 feet and narrower to 15 feet or more. The wider the mower, the more expensive it will be. A flail mower requires more power than a rotary mower because of its greater weight and size.

  • Flail mowers cut the grass into small pieces:

Flail mowers are an excellent option for people who want to leave the grass on their fields. The small pieces of grass left behind by flail mowers can be used as mulch around plants or flowers or used as compost.

  • The flail mower gets rid of stumps:

The flail mower removes stumps that may hinder the creation of a straight line. Stumps are cut in half and then removed, or they can be reduced to small pieces before being released with the mower.

If you have an old stump field where you need to create new landscape beds or borders around your property, consider using one or more machines like these at once. They don’t just clear away debris they make sure everything looks fantastic when done right.

  • Flail mowers make it easy to finish mowing jobs:

Flail mowers are easy to use. They’re simple, intuitive, and durable. You don’t have to worry about parts breaking or getting stuck in the lawn, as flail mowers can easily handle rough terrain.

  • Flail mower maintenance is also straightforward:

Brush off any debris from your lawn after every use of your flail mower before storing it away for next time.

What’s the Disadvantage of Flail Mower?

  • Uncut Grass in Wet Weather:

While a flail mower is an excellent option for cutting grass in wet weather, you must be aware of the potential for leaving uncut grass behind. This can cause your lawn to look unkempt and untidy if left long enough.

You may also find yourself having to deal with clumps of grass that are still attached to their roots after being cut by the blades of your flail mower.

  • Higher Speed:

When you’re talking about power, the higher the RPM (revolutions per minute), the more powerful your engine will be.

This is important because it means that if you have a slow-moving object like grass or plants in front of your mower, then there’s going to be more pressure on those blades, and they’ll have to work harder than they would if they were moving faster.

  • More Expensive:

If you’re looking for a mower that will save money in the long run, it’s probably best to go with one of the other machines.

Flail mowers are more expensive than other lawnmowers because they require more maintenance and parts, so they’ll need repair more often.

  • Maintenance Concerns:

Maintenance concerns are a significant disadvantage of flail mowers. Maintaining a flail mower is more challenging than keeping a lawnmower, as fewer parts are available for replacement. The flails themselves can be expensive and difficult to repair because of their intricate design.

In some cases, they require specialized tools or knowledge that aren’t commonly found outside the manufacturer’s service department.

How to Setup Flail Mower?

Setting up a flail mower is an easy task. Make sure you follow these steps and are good to go.

  1. Unpack the mower. Each flail mower comes with its cart, so unpack it and set it aside until needed. You may need to take pictures of how everything looks together before starting assembly.
  2. Assemble the mower on top of your tractor bucket, then attach all six wheels by tightening nuts onto their bolts that look like nuts.
  3. Please ensure they are tight enough, so they don’t wobble while cutting the grass but not so tight that they’ll damage any surfaces around them including themselves.
  4. If necessary, file down any sharp edges on each wheel. So there won’t be any problems later on down the road when trying to start up again after having used up all available fuel reserves during operation hours last week.

Is Flail Mower Better than Rotary Mower?

A flail mower is not necessarily better than a rotary mower. It depends on the particular conditions of the site and the operator’s requirements. Both a flail mower and a rotary mower are two different mower types that cut grass using other cutting methods.

A rotary mower has a heavy rotating drum with vertical blades that goes round and round to cut the grass using a scissor-like action. A flail mower has a heavy flywheel at the back, which spins to create a centrifugal force that whips the blades back and forth in a scything motion to cut the grass. 

When deciding between a flail mower and a rotary mower, consider the type of grass to be mowed, the terrain condition, and the amount of maintenance required.

For example, the flail mower is generally better than a rotary mower when cutting rough ground, whereas a rotary mower is better suited to mowing grass flatly.

How Much Horsepower Does it Take to Run Flail Mower?

The horsepower required to run a flail mower will depend on the weight of the machine and the area to be mowed. However, as a general guide, a flail mower with a flywheel weighing around 80 pounds can be powered by a 7.5 HP engine, whereas a motor of 15 HP or more will be needed to power a 100-pound flail mower.

When choosing a flail mower, it is essential to ensure that the engine’s horsepower matches the machine’s weight, as a smaller engine will not be able to power a heavier flail mower.

Is Flail Mower Good for Rough Ground?

A flail mower is particularly useful for mowing rough ground too uneven or steep for a rotary mower to reach. When cutting, the blades spin in a scything motion, and as the centrifugal force pushes those outwards, they can cut tall weeds and grass growing near the edge of the cutting path. 

A flail mower is particularly useful in areas that are too steep or uneven for a rotary mower. This can be useful for mowing vegetation such as tall weeds and grass that grows near the edge of fields.

What is the Difference Between Flail Mower and Topper?

A topper is a small flail mower cutting grass on a golf course or sports field. A flail mower is generally bigger and heavier than a topper and is used to cut longer grass, such as in fields and meadows.

Our Takeaways:

A flail mower is an incredibly efficient and simple-to-use piece of farm machinery that can be integrated into your everyday routine. A flail mower is made up of two rotating blades held by a pair of rollers and a central motor which connects them all. When you flick the handle of the device, the rollers move back and forth while the blades rotate around them.

The central motor powers the whole machine, which causes the blades to swing forward and backwards in a cone-shaped pattern. This action flails the grass and weeds into the soil, leaving your garden completely clean in the most efficient manner possible.

It is also worth noting that a flail mower is effective in removing both dry and wet kinds of grass, as well as weeds.
