John Deere announced today the release of the 46-ton 460E, the company’s largest articulated dump truck to date and the largest ADT available in North America.
The 460E ADT joins the 370E and 410E as the latest entry in Deere’s E-Series. Deere says the 460E was designed for mining, quarry, aggregate, highway and site development applications.
Like the 370E and 410E, the 460E ADT is powered by a John Deere PowerTech™ 13.5L Interim Tier 4 engine. The 460E is powered by 481 horsepower and features a ZF transmission with a high capacity retarder, eight forward gears and four reverse gears. In addition, the new John Deere hauler axles on the 460E are designed for heavy-duty applications and include on-the-fly differential locks, outboard planetaries and each axle is independently pressure lubed and filtered. The E-Series axles use internal wet disc brakes that utilize independent cooling circuits.
“This new truck design offers contractors some serious advantages in the market, including high power-to-weight ratios, gradability, and capacity,” says Mark Oliver, Deere’s ADT product marketing engineer. “One of the biggest customer inspired enhancements are the on the fly differential locks that can be applied at any speed, manually or automatically, for improved performance in poor conditions.”
Oliver explained during a Tuesday webinar on the new truck that allowing the differential lock system to run in automatic mode simplifies operation for new operators by taking the guesswork out of using the differential locks. When ground conditions get soft and difficult, the system will automatically control the axle differential locks as well as the inter-axle differential lock all while the truck is still moving. Meanwhile, an experienced operator can still choose to manually engage the traction controls.
One feature brought up a few times during the announcement is Deere’s new Adaptive Suspension Control System which improves stability on the 460E. The new suspension system is now standard on all E-Series ADTs.
