Product Description

The FM150 ATV Flail Mower, part of the FM Series Flail Mowers range by Chapman Machinery Ltd are designed from the outset to tackle tough mowing tasks including mowing on rough, wet & boggy ground where a heavier mounted unit could become stuck. Built to be exceptionally tough, yet have a low ground pressure for easy towing, the FM Series Flail Mower can go where other machines cannot.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 FM120 self-powered flail topper keeps the mass low to the ground for stability, and allows cutting easily beneath trees and overhanging branches.

The FM150 ATV Flail, like all the mowers in the FM Series Flail Mower range 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. Heavy-duty ‘bx’ type drive belts last longer and are more efficient than smaller units used on competing machines.

    Great machine goes through anything with ease only small criticism is when you wind up the machine off the floor you have to make sure you don’t go too far as it catches the electronics on the engine but that’s all other than than not had a problem with my machine since I’ve owned it

    I am delighted with this flail mower. I have owned it for almost a year and have had no problems with it despite tackling a lot of dense vegetation, mature rushes and rough wet ground. The Honda engine never misses a beat and has ample power for even the toughest situations. The robust construction and excellent balance of the machine make towing with a quad in rough or steep terrain safe and effective. All in all a terrific machine.

    Had the FM150 for almost a year now, awesome piece of kit, more powerful and quieter than a logic flail, recommend to anyone!

    The 150 Flail I have purchased is a really well engineered piece of kit. I have some tough terrain to get back into good heart and am confident this machine will be a great assistant! Did have a weld failure issue but the company had the parts here in a day or two, so all was repaired in an hour or so.

Front Break Bar – Tubular fender bar to protect wheels and feed tall material (eg. bracken, reeds) into the mower smoothly

Cutter Bar – Fixed cutter bar within the deck to increase mulching and reduce chop size, for faster cut material de-composition.

Twin Bogie Axle – Replaces standard axle assembly with rocking beam axle with two wheels (per side), for smoother travel over rough terrain. Can only be used with the wheels to the side, cannot be used with wheels trailing.

Engine Centre Mount – Engine is centrally mounted on the deck to provide 50/50 weight distribution for improved safety on steep terrain.

Forged Hammer Flails – Fitted in place of standard steel blades, the forged hammer flails are considerably heavier, harder and give a better finish when cutting tough material eg. reeds, bracken. Higher rotational mass improves mower performance when encountering heavy clumps of material.
