RDM34EXH Excavator Forestry Disc Mulcher
RDM34EX Excavator Forestry Disc Mulcher Overview
The RDM34EXH Excavator Forestry Disc Mulcher is one of the most compact units in our RDM Series, built for operators who need dependable performance in tight working conditions without giving up cutting power. This forestry disc is designed to handle standing timber more safely, making it a strong fit for jobs where control matters just as much as production.
At Advanced Forest Equipment, we build disc mulchers the way they ought to be built—out in the field, not in a lab. Plenty have tried to copy our work, but RDM technology is more than a spinning disc with teeth bolted on. Our proprietary design is engineered to transfer maximum power to the cutting disc using the carrier’s current hydraulic system.
The result is a harder-working mulcher attachment built for real forestry work, better efficiency, and the kind of reliable productivity serious operators demand.
RDM Series Excavator Forestry Disc Mulchers Increase Productivity by 40%
Owners running RDM Series excavator forestry disc mulchers have reported increased productivity of up to 40%. In the field, that means more clearing, less downtime, and stronger output from start to finish. With RDM technology, efficient hydraulic power transfer, and a proven cutting disc design, these excavator mulchers are built to help operators cover more ground without sacrificing durability or performance.
Key Benefits of the RDM34EX Excavator Forestry Disc Mulcher
Professional-Grade Performance
This forestry disc mulcher is designed, built, and field-tested to handle demanding excavator forestry applications and land-clearing work.
Better Visibility for the Operator
This disc mulcher is designed to give the operator a clearer view of the material being processed. Better visibility helps improve control during cutting and reduces unnecessary contact between the cutting disc, cutting teeth, rocks, and other foreign material.
No Extra Equipment Required
The RDM34EXH is built to make efficient use of your carrier’s existing hydraulic system to run the mulcher without requiring additional support equipment or a separate power pack.
Designed for More Efficiency
With the ability to mulch material up to 4 inches in diameter, the RDM34EXH delivers steady, efficient results across a wide range of excavator forestry applications, including vegetation management, land clearing, pre-commercial thinning, and fuel reduction for wildfire prevention.
Key Features of the RDM34EX Excavator Forestry Disc Mulcher
Fits CAT 309 and 8–10 Ton Excavators
The RDM34EXH Excavator Forestry Disc Mulcher is exclusively built for CAT 309 Excavators and 8–10 ton machines and designed to work with existing thumb attachment setups or quick couplers for quicker setup.
Digging Spade Feature Exclusive to RDM Series Only
Only RDM Series excavator mulchers from Advanced Forest Equipment come with our exclusive Digging Spade Feature. It gives the operator another tool in the field for digging, clearing overgrown roads, and loading logs without changing attachments.
Rugged Steel Mounting System
The mounting system is built for hard forestry work and the abuse that comes with it. It is strong enough to lift and reposition the excavator when needed, giving contractors the durability they expect from real forest equipment.
Rotary Disc Mulching System Designed for Efficiency
The RDM34EXH uses proven RDM technology with a 34-inch rotary disc mulcher, direct-drive power transfer, and a reduction shroud system that forces trees, brush, and vegetation into the fixed cutting teeth.
34 Diameter High-Strength Forestry Disc
This forestry disc is built from Weldox 700 and T-1 steel and measures 1¼ inches thick. It is made to cut through dense vegetation, including trees, of up to 4 inches in diameter.
Reduction Shroud for Increased Productivity
The reduction shroud system helps pull material into the mulching disc and fixed teeth for a finer finish and more consistent processing. That means cleaner results, greater material reduction, and greater productivity per pass.
Direct Drive Power Transfer
The RDM34EXH disc mulcher uses a direct-drive design to transmit power directly to the cutting disc for reliable mulching performance.
Heavy-Duty Bearing Box
The bearing box is fully tested and custom-built to withstand the load and protect critical components.
Bent-axis Piston Hydraulic Motor
The RDM34EXH excavator mulcher is equipped with a bent-axis piston hydraulic motor, a critical piece of the system that helps deliver efficient power to the disc.
Three Cutting Tooth Options
Different jobs call for different cutting teeth, and this unit gives contractors options. The RDM34EXH can be equipped with beaver teeth, carbide thumbnail teeth, or carbide bullet teeth, allowing the operator to match the disc mulcher to the material and working conditions.
With the ability to mulch material up to 4 inches in diameter, the RDM34EXH delivers steady, efficient results across a wide range of excavator forestry applications. As part of the RDM series, it’s used worldwide in vegetation management, land clearing, pre-commercial thinning, and fuel reduction for wildfire prevention.

RDM34EX Excavator Forestry Disc Mulcher FAQs
Does the RDM34EX Excavator Forestry Disc Mulcher Have Easy Maintenance?
The RDM34EXH Excavator Forestry Disc Mulcher is built to stay in the field, not in the shop. Maintenance is straightforward because the system is designed with fewer wear points and more dependable components.
- No belts, pulleys, or sheaves to adjust, replace, or fail under load
- Oil-bathed bearings for continuous lubrication and cooling during heavy mulching
- Heat-treated, precision-ground drive shafts built for long-term durability
- Rubber safety coupler designed to protect the hydraulic system and key components
Less complexity means fewer breakdowns, easier upkeep, and more productivity from your disc mulcher day in and day out.
What Is Not Included With the RDM34EX Excavator Forestry Disc Mulcher?
The RDM34EXH excavator forestry disc mulcher is sold as a complete mulcher attachment, ready to be matched with your excavator. Like most excavator mulchers, some components and services are not included with the base equipment:
- Optional equipment upgrades
- Hydraulic hoses
- Hydraulic quick couplers
- Freight and delivery costs
- Installation or setup costs
This gives contractors the flexibility to configure the attachment to match their machine, their hydraulic setup, and the type of forestry disc mulching work they are running in the field.
What Front Window Protection Is Recommended for the RDM34EX Excavator Forestry Disc Mulcher?
For the RDM34EXH Excavator Forestry Disc Mulcher, we strongly recommend installing an approved polycarbonate front window. It is built to withstand the impact of real mulching work, where debris, wood, and other materials constantly move under the cutting disc.
If you are unsure what setup fits your excavator or mulcher attachment, contact Advanced Forest Equipment for recommendations.
Are There Any Safety Precautions for the RDM34EX Excavator Forestry Disc Mulcher?
Follow these basic guidelines when running this disc mulcher attachment:
- Do Not Use on Open Cab Excavators: This forestry disc mulcher must be used on machines with fully enclosed cab protection. Open cabs do not provide the safety required for mulching operations.
- Do Not Use Tempered Glass Front Windows: Tempered glass is not built for excavator forestry applications. Install an approved polycarbonate front window before running any rotary disc mulcher.
- Maintain a Safe Working Distance: Never operate the mulching disc if anyone is within 300 feet of the machine. This is critical for protecting crew members and maintaining safe jobsite conditions.
