Versatility and Durability

The Frontier™ FL11S Series Flail Mower combines the toughness to cut brush with the finesse to leave turf grass looking polished. Its dual-purpose design handles everything from ditches and hedgerows to pond edges and turf, letting operators tackle diverse tasks efficiently without switching implements.

Hammer Blades for a Range of Conditions

The FL10 Series models come standard with hammer blades. These are great all-purpose durable blades, providing aggressive cutting for tougher conditions while also delivering a high-quality cut on maintained fields.

Side Shift Hydraulically for Hard-to-Reach Areas

The FL11S Series comes standard with hydraulic side shift, giving operators the ability to slide left of center 12 in. (30.5 cm) and fully extended up to 100 in. (254 cm), all from the seat of their tractor. Side shift is ideal for trimming along walls, buildings, trees with low-lying branches, fences, or orchards, making those hard-to-reach areas an easy cut.
