1050J Crawler Dozer Provides Enhanced Productivity

The John Deere 1050J crawler dozer retains the customer-driven features of its predecessor — the hydrostatic drive train, the integral power management system for maximum efficiency, Deere’s Auto-Trac system that keeps the machine tracking straight in forward or reverse, and heavy duty undercarriage that provides long life and a smooth ride. Numerous improvements, including an improved operator’s station and more powerful engine make the 1050J crawler dozer one of the most productive machines on the market, according to Dan Drescher, product marketing manager, John Deere Construction & Forestry Company.

“The benefits of this dozer are many — its rugged engine design, smart cooling system, state-of-the-art power train, excellent visibility and serviceability,” Drescher said. “All of these features add up to make the 1050J a rugged, productive, reliable and easily serviced machine.”

A new, Tier III certified, 12-L, six-cylinder engine with a wet sleeve design provides electronic fuel management and 335 net hp (250 kW) at 1,600 rpm. The slow engine speed delivers long life, low fuel consumption and extremely low noise levels. A deep oil pan assures full pressure lubrication on steep slopes. All essential maintenance points are grouped together on the right side of the engine, accessible through a hinged lockable door.

The Deere 1050J’s ease of operation and precise maneuverability are the direct result of its full-featured hydrostatic drive train, which is controlled by a single joystick. The drive train allows the Deere 1050J to deliver power turns under load, infinite speed control, power management, counter-rotation, dynamic braking and other productivity-boosting advantages.

With an infinitely variable speed range from 0 to 6.8 mph (0 to 11 kmh), the operator can choose the right ground speed for the job. Maximum ground speed is controlled by a simple switch, and all available power is applied, regardless of the selected speed setting. Charge air cooling delivers greater power and longer component life.

A five fin per inch heavy-duty radiator resists plugging and cleans easily, while the hydraulically driven fan reduces wear and adjustment of the drive belts. In addition, operating weight has increased, enhancing the stability of the machine.

The Deere 1050J’s two drive pumps and four drive motors efficiently deliver power to the ground with two drive motors dedicated to each final drive, resulting in more steering power and more than 116,000 lbs. (52,617 kg) of drawbar pull. Additionally, a new electronic control system allows the technicians to adjust the machine to the operator’s preferences, as well as perform diagnostics on-site using a laptop.

The operator’s station features numerous improvements that enhance comfort and productivity, including large access doors with easy entry and exit, a 15-degree angled seat, large adjustable armrests, standard leg cushions, suspended style decelerator, two footrests and left and rear windows that open.

The Speed-in-Grip control lever features a shorter height and throw, which makes steering and forward/reverse travel even more intuitive and low effort. Speed selection is performed with an in-grip rocker switch, similar to other J-Series dozers. The dozer control lever also features shorter height and throw, with a button for optional hydraulic blade pitch.

A new front console mounted monitor system with backlit gauges and a high visibility screen provides visual and audible alerts to keep the operator well informed of the machine’s operating status. A lunchbox holder and cup holder are standard.

A new 11.5 yd. (10.5 m), 159-in. (404 cm) wide semi-universal blade enhances both productivity and uptime. Improved blade curvature enhances loading and increases production, while clipped corners allow the operator to easily see when the blade is fully loaded. This helps the operator spend less time in the cut. Push beam trunnion joints use replaceable long-life half shell bearings, and the ripper is pinned directly to the frame, which enhances durability.

Like all Deere dozers, the 1050J’s daily and periodic service points are grouped, and lockable service doors provide wide-open access to dipsticks, sight gauges, fill tubes and filters. The cab tilts rearward with the removal of just a few bolts, and service intervals are generous, with 500 hours for hydraulic/transmission filter changes and 2,000 hours for transmission oil. Onboard diagnostics allow quick diagnosis and rapid repair.

“In addition to being rugged, productive and durable, this machine is easy to operate and maintain,” Drescher said. “It excels in virtually any dozer application that takes some serious size and muscle.”
