<p>DX85R-3 excavator</p>

Both the DX63-3 and DX85R-3 models include a blade float, multi-function joysticks, color instrumentation panel, Auto-Shift drive system, and standard rubber tracks. Their 59.4 hp diesel engine features a high-pressure common-rail fuel injection system, diesel oxidation catalyst (DOC) and a diesel particulate filter (DPF) and are compliant with Tier 4 standards.

The DX63-3’s upper-structure is shifted rearward on the undercarriage to increase efficiency. The DX63-3’s 11.6 inches of tail swing overhang improves its lifting performance without increasing the machine’s overall weight. The added tail swing also improves the DX63-3’s slew performance when working on side slopes. It is engineered to dig to depths of 13 feet 6 inches. It offers 5,767 ft.-lbs. of arm force, while bucket force has increased to 9,731 ft.-lbs.

The DX85R-3’s 5.8 inches of tail overhang allows it to work in congested environments and tight spaces and dig to depths of 15 feet 6 inches. The DX85R-3’s bucket force has increased for productivity when excavating or trenching with 14,509 foot-pounds of breakout force, and it offers 8,069 fft.-lbs. of arm force.

The blade float feature provides operators the versatility to smoothly grade, level, or backfill material. Operators can use one machine to excavate and fill material. It is the first time the blade float is available on Doosan excavators in this size class.

Both new Doosan excavators come standard with Auto-Shift travel, which shifts the excavator out of high range or low range and back automatically.

Both the DX63-3 and DX85R-3 excavators incorporate fingertip boom swing and auxiliary hydraulics functions. Independent boom swing control on the joysticks allows operators to position the work group for offset digging. Selectable auxiliary flow rates and the detent (continuous flow) mode allow for more exact attachment performance.

A new color panel displays fuel level, coolant temperature, day/time, throttle position, and engine rpm. Operators can select auxiliary hydraulic flow modes and rates from the panel.

New boom cylinder guards provide both excavators improved uptime protection, guarding the boom cylinder when the excavator is digging. Integrated into the undercarriage are four tie-down points to simplify trailer loading for transport. Extended grease intervals on the machines’ work groups minimize maintenance requirements, the company stated.
