Rex Roth Hydraulic Motors
Rex-Roth hydraulic bent axis piston motor-Rex-Roth manufactures the best hydraulic motors in the world. We typically experience 3,000 to 4,000 hours of service with these motors.
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. We have numerous attachments still running with over 8,000 on the original bearings. 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 excavators 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 in power and control between the mulching attachment and excavator.
RDM Mulching Attachments
They are manufactured to work with the excavators thumb. We manufacture each RDM attachment to match and mate your excavators thumb. Just like your dirt bucket, we can pick up rock, dirt and other objects with the mulcher/thumb combination.
