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.



POWER & PERFORMANCE - Using an industry-leading 21hp Honda GX630 V-Twin Engine, which offers 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.
