Pre-Sale FAQ & Product Specifications

Advanced Forest Equipment is not only the manufacture of disc forestry mulching attachments, we are also a 35-year forestry mulching contractor here on the west coast of the good ole USA. We know how important it is for you to get quick answers to your questions. Please read the following Q & A to get the answers for the most common questions.     

Question: Other forestry mulchers/mowers need either a dedicated carrier or an additional power pack to operate. How is the RDM™ able to operate on the existing carrier hydraulic flow?

Answer: This was one of the first requirements that Jon Moffet realized must be met in order to create a cost-effective means for fuels reduction work. Jon spent many hours designing and testing his pending gearbox to achieve this. He designed a set of gears and bearings that work so efficiently they eliminate the need for external power. We're not telling what goes on in there... that's our secret!


Question: How is the RDM™ able to provide such consistent mulch?

Answer: RDM™ Technology success is based on the synergy of the cutting disc rpm’s, cutting teeth placement and the reduction shroud design. All three have to work in harmony to be able to achieve true mulching capabilities.  "The attachments do what AFE says they can do. You can get more production out of a smaller base machine without doing any expensive modifications to the excavator. If your excavator has auxiliary hydraulics to run a hammer or breaker, you can easily run an RDM attachment."


Question: What additional controls are needed on the carrier to operate the RDM™?

Answer: None! The RDM™ does not need any add-on controls.


Question: How long does it take to install or remove an RDM™ attachment?

Answer: This depends on the carrier and the type of disconnects you order with your RDM™. The changeover ranges from 5 minutes to 15 minutes. Either way, your carrier maintains its versatility.


Question: Who will service or repair the RDM™?

Answer: Maintenance and service are simple for the RDM and many of our customers do routine tasks themselves.  Advanced maintenance training is available as an option.  We also have an 800 # for technical assistance.


Question: Where can I buy parts for the RDM™?

Answer: All bearings, seals, pistons are OEM parts and can be obtained from your local heavy equipment dealer or any parts supplier in the heavy equipment business. The shaft and bearing box are proprietary products and must be obtained through Advanced Forest Equipment. We stock a complete line of parts at our manufacturing facility and can provide express shipment to most anywhere in the world.


Question: What is the warranty on the RDM™?

Answer: Direct from Advanced Forest Equipment we offer a 6-month warranty that covers the RDM™ from defects in material and workmanship. Some OEM parts have warranties available directly from their manufacturer. (Refer to the warranty information card for a complete description of the warranty).


Question: How many models do you have in the ECO Series Line?

Answer: We have four models under our ECO Series Line. The SS ECO Mulcher is designed for Skid Steers. We have three different models for excavators, 34ECO, 38ECO, and the 44ECO.


Question: Do the ECO Series Mulchers have an edge over the RDM™ Series?

Answer: Our ECO Series offers the same outstanding performance at a lower more affordable cost.  The ECO Series utilizes a bolt on the adapter plate mounting system so you can easily and efficiently move this mulching implement between excavators.  This is a lighter duty mulching attachment, ideal for the smaller contractor, farmer, ranch or landowner.


Question: What kind of life should I expect out of the RDM™?

Answer: Contact Jon in our Sales Department to go over specific RDM™ Model warranties. The RDM™ 30, RDM™ 34 and RDM™38 have 6-month warranties, the hydraulic motor is an OEM Product and is covered by the Manufacturer directly not by Advanced Forest Equipment. The RDM™ 44 & 52 RDM™ have 12-month warranties, the hydraulic motor is an OEM Product and is covered by the Manufacturer directly not by Advanced Forest Equipment.

 

RDM Product Line Specifications

Rex Roth Hydraulic Motors

Rex-Roth hydraulic bent axis piston motor-Rex-Roth manufactures the best hydraulic motors in the world. 

Bearing Box

Oil-bathed bearing box with heat treated shaft. Our output shaft is 6” in diameter and they are heat treated for additional strength.  Oil-bathed systems run cooler with better lubrication than grease systems and required no daily maintenance.

Reduction Shroud System

Reduces debris field but more importantly, this system aids in a one cut method by pulling the cut material into the reduction shroud forcing the material directly into the cutting teeth surfaces resulting in faster mulching with smaller treated mulch size.

Digging Spade Feature

This allows the operator to clear and clean ditch lines, pull material for quicker mulching, mates to the excavator's thumb to move material or load material into trucks, aids in movement of the excavator.

Structural Mounting System

This is the strongest design for mounting mulching attachments and digging buckets for excavators. This allows for the digging and pulling operation without collapsing the mulching attachment.

Variable Speed Capability

One of the most important features of the RDM™ mulching attachment is for the operator to have the ability to regulate the speed "RPM's" on the mulching attachment. Different material species require slower or faster speeds when mulching. Faster production with smaller mulch size is a result when running variable speed mulching attachment. Safe operation of mulching attachment with more control for your operator.

RDM52EX

This attachment requires 60-70 GPM with 4,500 – 5,000 PSI. This mulching attachment is not manufactured as a generic model. We manufacture each attachment for your specific machines hydraulic flows and pressures to get the best match for power and control between the mulching attachment and excavator.

RDM Mulching Attachments

They are manufactured to work with the excavator's thumb. We manufacture each RDM attachment to match and mate your excavator's thumb. Just like your dirt bucket, we can pick up a a rock, dirt and other objects with the mulcher/thumb combination.
