The 260E and 310E ADT’s have updated styling, new cabs, frames and axles.
The 26-ton 260E (235 kW / 321 hp) and 31-ton 310E (260 kW / 354 hp) use a John Deere PowerTech™ 9.0 Liter Final Tier 4 engine. A purpose-built ZF transmission includes a high-capacity retarder, eight forward gears and four reverse gears. Compared to previous models, these trucks have a 125 percent increase in retardation capacity. A new automatic differential lock provides both cross-axle differential lock and inter-axle differential lock options that can power the ADTs through soft underfoot conditions or steep terrains. In addition, the new John Deere hauler axles are designed for heavy-duty applications, and an optional cooling package is available for extreme conditions. Hydraulically actuated wet disc brakes are included in all three axles.
The updated ADT models use high-strength materials to provide durable, long-lasting structures while keeping a strong focus on overall weight and distribution. The machines have good power-to-weight ratios and hauling efficiencies. A newly designed stay-tight oscillation joint, standard adaptive front suspension and balanced weight distribution also provide the agility and ability to navigate difficult terrain. To minimize the risk of rollover while unloading, the dump body can be restricted from rising when the rear chassis exceeds a predetermined slope angle.
In the cab, sound levels have been reduced by 50 percent with the addition of sound abatement and improved floor mat design, providing operators with a fatigue-resistant working environment. When in the operator's seat, the cab monitor has an easy-to-read LCD screen with onboard diagnostics, digital gauges and vital system indicators. Two ergonomically positioned sealed switch modules simplify operation and convenience controls. The auto shutdown feature can turn off the engine after an owner-determined period of inactivity to help save fuel while reducing emissions, idle time operation and subsequent wear on the power train and hydraulics. Productivity is improved with standard features such as auto dump, descent control, shuttle shifting, hill hold and load assist. The 260E and 310E both feature centralized, true ground-level servicing to simplify daily maintenance and overall serviceability. Source
