A New Breed of Power, Precision & Safety
Limb Beaver is proud to announce the launch of the TDM Series Twin Disc Mulcher—a groundbreaking attachment engineered for contractors who demand high production, exceptional control, and low operating costs. Designed from extensive development, customer input, and rigorous field testing, the Twin Disc Mulcher represents the next evolution in vegetation management technology.
This new unit blends the raw production capability of a disc mulcher with the stability, safety, and consistency of a drum, creating an entirely new class of equipment that outperforms traditional single-disc systems in both output and controllability.
A Perfect Balance of Performance & Protection
The TDM Series doesn’t just cut—it redefines what an operator can expect from a mulching attachment.
By combining two counter-rotating discs with a short center of gravity, high-strength steel construction, and strategically engineered debris control, Limb Beaver has created a mulcher that is fast, stable, and predictable. Operators enjoy improved visibility, smoother operation, and a safer working environment—all without sacrificing production.
Contractors will immediately notice:
- Exceptional visibility without needing to constantly reposition
- Reduced debris ejection thanks to a controlled discharge path
- Stable operation, even on uneven terrain
- A uniform mulch size without repeated processing
In other words: big power, small learning curve.
Twin Disc Technology: Twice the Cutting, Twice the Output
At the heart of the TDM Series are its two 36” counter-rotating discs, delivering a massive 72-inch cutting width. This central cutting position and front-and-center debris discharge allow operators to process material quickly and accurately.
Key Twin Disc Advantages:
- Large 72” cutting width (2 × 36”)
- Faster recovery for higher overall production
- Controlled debris flow for safer operation
- Centralized cutting for predictable machine behavior
This configuration eliminates the instability associated with oversized single-disc units while dramatically increasing throughput.
Built on a Strong, Agile Frame
The TDM frame was engineered for contractors who work long days and demanding terrain. Light enough for agility but strong enough for heavy commercial use, it delivers unmatched durability and control.
Frame Highlights:
- Short center of gravity enhances stability
- High-strength wear plates in critical stress zones
- Robust structural steel for long-term dependability
- Optimized for visibility and operator control
Unlike bulky drum mulchers or unbalanced disc units, the TDM provides the perfect balance of maneuverability and strength.
Counter Anvils for Cleaner, More Predictable Output
Behind the cutting edge, the TDM uses three machined, replaceable counter anvils that improve chip quality while protecting the discs themselves.
Counter Anvil Benefits:
- Prevent large material jams
- Reduce disc wear and extend lifespan
- Produce smaller, consistent mulch chips
- Improve efficiency with minimal reprocessing
These anvils work in harmony with the twin discs to achieve a clean, uniform mulch finish every time.
Powered by Pair of Radial Piston Motors
Driving the TDM’s high-output cutting system is a dual-motor configuration built for real-world performance.
Motor System Highlights:
- Two 115cc radial piston motors
- High torque at low RPM—where standard motors fail
- Operates at 36 GPM @ 4000 PSI (95–165 HP machines)
- Broad torque curve for consistent productivity
This extended torque range delivers confident cutting through dense brush, hardwood limbs, and tough vegetation without bogging down.
Efficient, Economical Tooling
The TDM uses Beaver teeth*—a single, universal tooth type that’s widely available, economical, and easy to replace. With *2 × 26 teeth, it’s designed for reliability and straightforward maintenance.
Tooling Advantages:
- One tooth style throughout the entire attachment
- Economical, easy to source, and simple to maintain
- Effective across a wide range of material sizes
This reduces downtime and keeps long-term operating costs low.
A New Era for Contractors
The Twin Disc Mulcher isn’t just an upgrade—it’s a breakthrough. Faster than a drum, safer than a traditional disc, and more predictable than anything in its class, the TDM Series is built for operators who want results without compromise.
- Higher production
- Lower cost of ownership
- Safer operation
- Smoother performance
- Faster cleanup
- Less fatigue
Contractors, land managers, and vegetation control professionals have been asking for a mulcher that delivers both power and control—and Limb Beaver has delivered.
The new Twin Disc Mulcher is here. And it’s ready to change the game.
