John Deere has added a new PowerTech E 6068 Tier III engine to its 710J backhoe, improving both emissions compliance and power.

“Deere’s got the most powerful backhoe available at this size level, so contractors can step up to Tier III engines without sacrificing power, durability or lugging power,” said Bob Tyler, product marketing manager, John Deere Construction & Forestry Division.

The 710J still provides a dig depth of up to 22 ft. 4 in. (6.8 m) when extended. And now a PowerTech E 6068 Tier III engine that will come standard on 710J backhoes beginning in January will provide an increase in horsepower and the same heavy-duty six-cylinder torque as on the previous Tier II 710Js.

The new 710Js feature net horsepower of 126 hp (94 kW), compared to the 123 hp (91.7 kW) on the Tier II engines, along with a host of other improvements, Tyler said. For example, the high pressure common rail fuel system provides higher injection pressures, variable timing, and precise control of fuel injection, giving it highly efficient combustion.

“The increased combustion efficiency, power and torque results in higher low-speed torque and faster response, while the new ECU has twice the memory and five times the computing power of the previous engine,” Tyler said. “Plus, the redesigned ECU is now located inside the cab and your in-depth diagnostics can be retrieved using the monitor’s onboard diagnostics or Service Advisor.”

Deere also has ensured that daily servicing duties are easy to accomplish.

“Servicing is all done on the same side and accessed from the ground,” Tyler said. “You won’t need to raise the boom and no tools are necessary to open and tilt the hood, which can be tilted to 90 degrees if needed.”

In addition, exterior upgrades to the 710J include a new extended grill frame that comes standard and a side louver that improves airflow to the engine.
