RDM Series Excavator Forestry Disc Mulchers Increase Productivity by 40%

Key Benefits of the RDM38EX Excavator Forestry Disc Mulcher
Built by Contractors, For Contractors
The RDM38EX excavator forestry disc mulcher is built for hard use in the field, not light-duty work. Part of the RDM Series, this forestry disc mulcher is handcrafted and field-tested to withstand demanding excavator forestry and land-clearing jobs day after day.
Enhanced Operation Visibility
This excavator disc mulcher provides the operator with a clear view of the material, helping reduce contact between the mulching disc and cutting teeth and rocks and other foreign debris.
Less Equipment, Less Hassle
The RDM38EX uses your excavator’s hydraulic system efficiently, delivering the power needed to run the disc mulcher without an additional power pack or support equipment.
Mulch Overgrown Roads With Less Effort
With proper hydraulic flow, the RDM38EX excavator can handle trees, brush, and heavy vegetation up to 8 inches in diameter. It is a hard-working forestry disc attachment built to take on serious clearing work and keep moving.
Key Features of the RDM38EX Excavator Forestry Disc Mulcher
The RDM38EX excavator forestry disc mulcher is built to fit 10–15 ton excavators and work with your existing thumb attachments or quick couplers. That means less setup trouble and a better fit for the machine you already run.
Found only on the RDM Series, the Digging Spade Feature gives operators a practical edge in the field. You can dig, clear overgrown roads, and transfer logs without switching attachments. More work gets done with less downtime.
This mounting system is built for real forestry equipment work. It is strong enough to lift and reposition your excavator when needed.
The RDM38EX features a 38-inch rotary disc mulcher with a direct-drive system and a reduction shroud that feeds trees, brush, and vegetation into the fixed cutting teeth. The result is fast, steady mulching with fewer passes and less wasted motion.
The 38-inch forestry disc is built from Weldox 700 and T-1 steel and measures 1¼ inches thick. It can go through dense brush, heavy growth, and trees up to 8 inches in diameter without clogging.
The reduction shroud vacuums vegetation into the mulching disc and cutting teeth for finer mulch, cleaner results, and more production in less time.
The RDM38EX disc mulcher uses a direct-drive system that delivers power directly to the cutting disc via a heavy-duty bearing box. Fewer complications. Stronger transfer. Reliable mulching performance where it counts.
Every AFE disc mulcher comes with a fully-tested, custom-built bearing box.
This hydraulic motor sends power from the excavator directly to the forestry disc. It delivers consistent torque and dependable cutting performance without the need for extra hydraulic systems or added support equipment.
Contractors can choose from multiple cutting tooth options, including beaver teeth, carbide thumbnail teeth, and carbide bullet teeth.
Advanced Forest Equipment has dedicated nearly 37 years to the land-clearing business to develop a product line that continually outperforms other mulcher designs under the same harsh working conditions. With an RDM44EX Excavator Forestry Disc Mulcher, you can take on the harshest work, day in and day out.

RDM38EX Excavator Forestry Disc Mulcher FAQs
Is the RDM38EX Excavator Forestry Disc Mulcher Easy to Maintain?
Yes. The RDM38EX excavator forestry disc mulcher is built to keep maintenance simple and downtime to a minimum:
- No Belts, Pulleys, or Sheaves: This disc mulcher does not rely on belts, pulleys, or sheaves that can wear out, slip, or fail under hard forestry mulcher workloads.
- Oil-bathed Bearings: Oil-bathed bearings provide continuous lubrication and cooling to help the forestry disc mulcher run more smoothly, stay protected, and last longer under demanding job conditions.

What Front Window Protection is Recommended with the RDM38EX Excavator Forestry Disc Mulcher?
