*FM120 Pictured. 


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.


  • Front Breaker Bar - Ensures tall materials (e.g reeds or bracken) feed evenly into the rotor for consistent cutting performance

  • Chop Control Cutter Bar - Adjustable cutting bar within the deck to increase mulching and speed breakdown of cut material

  • Auto Idle - Idle function on an electronic switch for periodic cutting (e.g. Cutting heather fire-breaks on moorland)

  • Twin Axle - Twin wheels on bogie axles for smooth towing over the roughest terrain

  • Engine Centre Mounting - Engine is centrally mounted for 50/50 weight distribution giving greatly improved stability on steep ground

  • Hammer Flails - Forged & hardened hammer flails for cutting brush or to give the cleanest cut and finish on grass
