“Exceptionally tough & heavy duty”

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.

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!!!
