FM31 Series Flail Mowers

Available Models



Land Pride's FM31 Series Flail Mowers feature the same tough components as our 41 Series, but with blades offering a fine cut. The rear roller, which acts as the cutting height gauge, has tapered ends to eliminate gouging during tight maneauvers. Easily offset the hitch for a closer cut alongside buildings, fences, roadsides or for getting under tree limbs. A formed scraper keeps the roller free of moist grass and mud so cutting height is not disturbed.
