Flail mowers can give you a smoother, more complete cut in overgrown areas than Rotary Cutters, and they thoroughly shed and scatter clippings. For large or overgrown acreage, the Heavy-Duty 918H Flail Mower fits tractors up to 70 hp equipped with a 540 rpm PTO (Power Take-Off). It can be used with Category I or II hitches, without adding lift links or other parts. Cutting widths available: 60", 71" or 91". For thorough mulching, the Lighter-Duty 918L Flail Mower fits tractors up to 30 PTO hp equipped with a Category I hitch. Select a 50" or 60" cutting width.

Flail Mower on Tractor
Cutting knives rotate vertically at 2100 rpm for a fine, even cut. This reduces the chance of objects being thrown from the mower.
Blades are reversible for long life. Single-bolt mounting makes replacement easy.
Allows the Flail Mower to float independently with ground contours for uniform cutting on uneven terrain.
Rotor direction can be reversed for mulching. Forward rotation of the rotor knives lifts the grass for even cutting. Reversing the rotors allows for thorough mulching of the clippings and throws them to the rear where they are evenly distributed.
Mower can be centered behind the tractor or offset for close cutting next to buildings, walls, shrubbery or other obstructions.
Blades yield when they strike an object, reducing blade damage and maintaining an even cutting pattern.
Cutting height can be adjusted from 1" to 5".
The blades are mounted with a single hinge to a rotor positioned across the direction of forward travel, so blades are parallel to the ground and in line with the mower's direction. Cupped blades for greater lift are available.
Clippings are thoroughly shredded by the reverse rotation of the rotor blades, then thrown to the back of the mower where the extended rear skirt helps to distribute them evenly.
The Rear Gauge Roller allows the mower to follow ground contours.
Because the Flail Mower sits off-center, it allows you to easily trim close to trees and buildings. Your Boomer Tractor and mower respond as a single unit for greater maneuverability.
