Deere 710G Backhoe Tackles Tough Assignments

Wed August 09, 2006 - National Edition

Numerous enhancements over the previous model make John Deere’s 710G backhoe well suited for tough jobs, particularly those where a small excavator and loader are used together, according to Bob Tyler, product marketing manager, John Deere Construction & Forestry Company.

“The 710G provides the kind of digging force and lift capacity that customers typically find only in a 12-metric-ton excavator, and on the front end it rivals most 2-yard loaders,” he said. “In many cases, it can maximize productivity by taking the place of a loader and small excavator used in combination.”

The overall design of the 710G has been updated from the previous model, including the boom, loader arms, cab and tilted hood, all of which feature numerous design improvements.

The only backhoe on the market powered by a 6-cylinder engine, the 710G’s 118-net-hp John Deere 6068T diesel is Tier II emissions compliant.

The pressure-compensating, load-sensing hydraulics are the same as the system used by Deere’s 410G backhoe.

A 70-gal. fuel tank allows the 710G to work longer without re-fueling.

“Mobile” productivity is delivered through a wide variety of tools, including couplers, hammers, buckets, forks, compactors and more. Two lever pilot controls are standard.

“The 710G is a go-anywhere, do-anything machine,” Tyler said. “Every feature was designed with productivity, serviceability and reliability in mind.”

Backhoe Features

Longer, box-constructed stabilizers provide stability through a stance that is 18 in. wider, yet transport width has decreased.

Stabilizer downforce has been increased by 74 percent, swing torque has been increased by 72 percent, and bucket dig force has increased by 4,000 lbs.

“These improvements enable the 710G to use more power for the job, so tasks like swinging uphill and sweeping dirt back into a trench are accomplished quickly and easily,” Tyler said.

Replaceable wear strip on the swing casting eliminates hose wear; replaceable bushings in the swing cylinder casting help maintain tightness; a boom lock eliminates the need for cable; and a rubber backhoe boom stop eliminates “chucking” when driving on the road.

Loader Features

Loader arms are stiffer and heavier than the previous model. Both the arm and mainframe are box-constructed of high-strength low-alloy steel and robot welded, and the mainframe is better balanced for enhanced ride when driving on the road or transporting by truck.

The high-knee loader design allows the use of larger tires, as well as providing better front tire clearance.

The bucket features numerous improvements. Loader bucket dump angle is increased to 45 degrees for better bucket clean-out, and 25 percent more bucket corner prying force. The bucket joints are positioned higher, keeping them out of the dirt.

Loader pins are bolted in place with replaceable internal bushings. Bucket pins also are larger.

The largest backhoe-loader in Deere’s product line, the 710G can tackle the toughest jobs, according to Tyler.

“In many applications, the 710G delivers the production-loading ability of comparably sized 4-wheel-drive loaders,” he said. “Rather than the loading and unloading you have to do with an excavator, the 710G can go from job site to job site in a few minutes, leaving a lot more time available to work,” Tyler said.
