The Model 84E Asphalt Recycler is a tow-type machine with a 84 inch (7 foot) cutting width. With a 450 horsepower diesel engine dedicated to the cutter drive, the Model 84E has more horsepower per foot of cut than any machine in its class. Combined with a 100% mechanical drive line, the 84E puts all of the available power to the cutter drum, unlike self-propelled machines that use a portion of the power to propel, steer, etc. This additional power is a key to the production and performance of this design. And, the mechanical drive is more efficient and less expensive to maintain.
The standard cutter drum for the Model 84E has a maximum cutting depth of 8 inches, with an optional reclaimation drum allowing a 12 inch cutting depth. The arrangement of the cutter bits on the drum (bit-lacing pattern) is designed for optimum performance in the Partial-Depth, Cold, In-Place Recycling method of road rehabilitation. Since the graduation of the milled material is the single most important factor for consistent quality in the recycling process, Maddock Construction Equipment has used extensive testing to determine the best combination of bit-lacing pattern and drum speed to achieve this quality of material gradation.
