“Maintenance made easy, tackle tough terrain with the ATV Flail Mower”

Reliable Honda engine plus extremely robust build quality with fine attention to detail ensures these mowers withstand years of use

Designed for the full range of topping and mowing tasks, from thick dense rushes to fine topping of parkland, our range of Flail Mowers can tackle anything thrown at them.

  • Powerful 21hp Honda Petrol Engine
  • Heavy duty construction throughout
  • Unique double helix flail rotor
  • Large diameter tyres for smooth travel
  • Automatic belt tension system
  • Heavy duty ‘Y’ flails

Power & Performance

We use industry-leading 21hp Honda GX630 V-Twin Engines, which offer unparalleled power and performance. All machines are fitted with a heavy-duty rear roller to prevent scalping.

The compact design of the FM Series self-powered flail topper keeps the mass low to the ground for stability and allows cutting easily beneath trees and overhanging branches.

Clean & Reliable

The FM Series are fitted as standard with a centrifugal clutch, allowing for safe & efficient operation from the towing machine.

The centrifugal clutch gives automatic drive engagement and disengagement, and combined with the automatic tensioning assembly reduces maintenance by compensating for belt wear and belt loading.

Unique Rotor Design

Our innovative rotor design incorporates a solid 40mm diameter drive shaft right through the centre of the rotor with a structural grade 90mm diameter outer tube, onto which the flail lugs are welded in a spiral pattern.

This unique design transfers cutting power more efficiently from the engine to the cutting heads, giving a cleaner cut and better performance in tough situations. Furthermore the rotor incorporates dedicated bearing guards designed to prevent string and wire damaging the bearings.

Class leading

The FM Series feature heavy duty steel ‘Y’ flails for a clean and effective cut whatever your scenario.

Simple height adjustment for ease of use and heavy duty & robust B Section drive belts for low maintenance ownership, complete the package for this class leading ATV Flail Mower.

Vehicle Flexibility Compatibility

Simple cutting height adjustment, large wheels and easy-to-use design along with the ability to fit on a variety of vehicles such as ATV, UTVs and 4x4s make these machines a pleasure to use. This versatility ensures that you can use the flail mower with multiple vehicles, making it a practical and cost-effective solution for your agricultural or landscaping needs. It’s incredibly quick and easy to hitch up and get mowing, perfect for those small maintenance tasks and keeping on top of weeds and other vegetation.

Flail Mowers Built to Last

Our ATV flail mowers are durable and reliable machines, made in Britain to last. With 5mm steel on the main deck, and up to 15mm thick steel elsewhere, the ATV Flail Mowers really are a quality product designed for years of use and abuse in tough terrain. It’s one of the heaviest duty flail mowers on the market, ensuring optimal performance and efficiency, and a long service life.

You can trust that your ATV flail mower will provide you with superior cutting ability and longevity for years to come.

What is an ATV Flail Mower?

ATV flail mowers are a key piece of agricultural equipment which have been designed to attach to a range of vehicles such as an ATV, 4×4 or UTV. ATV Flail Mowers are commonly used on farms, smallholdings, estates and paddocks for cutting & mulching grass, weeds, bracken, ragwort and other vegetation. Powered by a Honda GX630 V-Twin electric start engine, with 21hp, there is plenty of power to make short work of tough mowing and cutting.

Benefits of an ATV Flail Mower

An ATV Flail Mower is one of the most versatile and cost-effective ways for farmers, smallholders and landowners to maintain their land with many benefits such as:

  • Cost-effective way to maintain fields and paddocks using existing towing vehicles
  • Much easier & quicker to connect up and use than tractor mounted units – easier to use for operators
  • Improves the overall health of the land by mulching and recycling vegetation back into the soil
  • Helps prevent the spread of weeds and invasive species with timely cutting to prevent flowering and seeding
  • Can be used to maintain hard-to-reach areas where a tractor-mounted mower may not be practical or safe

I’ve recently purchased a Chapman FM120 flail mower from Mark Keys Quads Fermanagh, Northern Ireland. My brother and myself started a contracting business about 4months ago and we were looking for an ATV mulcher. We had a Logic and Quad X out on trial, both of which we found to be underpowered and lightweight then we heard about the Chapman so we went looking for one. Keys Quads luckily had one in stock, so went to see it. We arrived and the Chapman was out ready for our inspection and at first glimpse we knew it was worth our visit!

The strength and size of the mulcher was absolutely amazing, we quickly made the purchase there and then!!! Since then, we have been out mulching everyday with it and all I can say is, WOW, this machine is bulletproof!

Thanks for making such an amazing wonderful piece of equipment!

Awesome piece of kit! I have cut through brambles 3-4 feet high as well as rushes, thick tufts etc. etc.
Very well built and highly recommended.

Mike Barritt3rd July 2016

I would only buy a UK made machine as the Chinese alternatives just don’t have the grunt nor the build quality and I have not been disappointed. Fantastic piece of kit and I would recommend this to anyone. Thanks Chapman!!

Perry Rigler28th July 2016

I can’t fault the machine for build quality and strength – it powered through the highest of rushes and left the paddock spotless. When coming over a big clump of rush all you have to do is slow down and give it a chance and it mulches right through it. I would highly recommend this machine to anyone and the extra money spent compared with the other brands is more than worth it for a quality machine.

Padraic Maguire11th August 2016

It started first turn of the key and cut perfectly for a hour and a half. This machine is a credit to your company and everyone who works there, the high quality, workmanship, and finish of the unit, and your professionalism throughout my purchase has made the whole transaction a dream so thanks to you and your entire team.

Kevan Maguire17th April 2017

Excellent flail mower. Well built, good powerful Honda engine, easy to use and had no trouble going through 4-5ft deep weeds/nettles and grass. Pleased and would recommend.

Andrew Spink6th July 2017

Fanstastic machine. I use the flail to cut horse paddocks and the local rugby club pitch both situations it does a fanstastic job. Great service back up from Chapman. Great to support a British manufacture.

Nick Wiltshire28th September 2017

Have bought the FM 120 with hammer flails……..Just amazing bit of kit !!! Built like a tank, very easy to use, best engine in the business ( Honda), very powerful, surprisingly quiet and just chews through, bracken, thistles, reeds, brambles, hogweed you name it . Very pleased with the purchase and wouldn’t hesitate to recommend over any other machine or make . Thank you Chapman!!!
