Standard features at a glance
The CPR makes sure you don’t bite off more than you can chew, and controls the discharge particle size. The drum features easily replaceable hardened steel wire cutters that prevent wire from winding around the drive shaft between the end of the drum and frame, damaging the bearing seals. All of the CPR holders and plates on the drum are manufactured from high strength steel for superior impact resistance and longevity. Keeps production rolling while creating a consistent mulch in a single pass.
The Teeth
The drum accepts multiple tooling options to suit any budget, performance and ground conditions. Including: Promac’s proprietary reversible knives or “chipper teeth”, double carbides and the standard beaver teeth.
The Frame
Incorporates high-strength steel with full-strength welds for durability. Machined bearing plates within the boxed-in ends increase rigidity and durability, resulting in longer bearing life and lower weight.
The Motor
The combination of the variable torque bent axis motor with the Promac Automatic Torque Controller (ATC) is a new Promac innovation that continuously matches motor displacement with the available hydraulic power for sustained drum speeds and increased productivity.
THE PARTS
Promac knows these machines are operating in extreme conditions where normal mild steel will not hold up well in the long term. Abrasion resistant steel, AR400, is incorporated in high wear areas and in components that are replaceable ensuring longevity and easy maintenance. The replaceable parts include: The wear liner, the bolt-in skid shoes and the bolt-in rear anvil.
Versatile Tooling Options
The HSM60 can be equipped with tooling tailored to suit the job conditions and desired end product. The machine comes with our standard chipper teeth that can be easily sharpened, reversed, and replaced. For best results in extreme conditions our double carbides are recommended. Beaver teeth are another great option for most working conditions.
Beaver Teeth
Works for most conditions.
With the addition of a specialized adapter, the HSM60 drum can be transformed to accept very common and widely available 2 5/16″ beaver teeth.
Double Carbides
Best for rocky conditions.
Promac’s Double Carbide Teeth are extremely tough, lasting up to 500 hours. Because the attachment is more likely to make contact with rocks and other hard materials on the ends of the drum, we recommend purchasing Double Carbide Teeth for the outer 4 rows on each end of the drum (16 teeth), and leaving the middle section with the more efficient Chipper Teeth.
Chipper Teeth
Best for sand or soil conditions.
These can be sharpened, reversed, and replaced easily. They are extremely efficient at mulching wood and last between 40-100 hours per side depending on the conditions. They deteriorate quickly in rocky conditions.

Built with safety in mind
Discharge control is important when working near the public or buildings. The trajectory of the front discharge is within 5’ feet of the machine when operating level vs. 20-50’ on other open face mulcher machines.
A hydraulic drum brake is an option for those operators that are safety focused. The brake can bring the drum to a rapid stop to protect the operator and other workers.
