The 17-inch-diameter Battle Ax rotor includes built-in depth gauges, which function similarly to raker teeth on chain saws to prevent the attachment from engaging too much material at one time. This unique design is more ideal for managing the amount of material being fed into the attachment than competitive ring-style rotors, which many operators find to be overly limiting, especially when using carbide cutting teeth.
The Battle Ax features the Loftness-exclusive two-stage cutting chamber design, which is capable of processing material more thoroughly than competitive units by cutting material twice. Not only does this allow faster decomposition, but it also results in a nicer looking end product. Material is first cut at the primary shear bar, which is adjustable, so the clearance can be narrowed or widened depending upon the desired material size and production rate. From here, the partially reduced material passes smoothly to the secondary cutting chamber behind the front bumper, where it’s processed further before being discharged toward the ground.
The 30 Series Battle Ax features a 105cc adjustable displacement piston motor for excavators with hydraulic systems ranging from 20 to 60 gallons per minute and up to 6,000 PSI (45 to 150 hydraulic horsepower). This motor turns the rotor from 2,000 to 2,600 RPM and can be manually adjusted for fine-tuning performance on a variety of excavators.
The positive drive, cog belt and sprocket design increases efficiency and requires less maintenance than other drive types.
A staggered tooth arrangement ensures single-tooth contact with the work surface at all times while maintaining optimal rotor balance.
The cutting teeth are mounted to the rotor with a single bolt. They can be easily reversed or replaced on the jobsite using a common hex socket.
The rotor ends mate with close tolerance machined anti-wrap rings, resulting in minimal debris in the bearing chamber.
The Battle Ax is constructed of high-strength steel to withstand some of the toughest operating conditions.
