The P-Tier articulated dump trucks from John Deere, Moline, Ill., include the 410 and 460 ADTs. The models retain the same fuel efficiency, dump body and drive modes as the previous E-II models, the company said. For all P-Tier models, additional updates to the external styling and interior cab layout modernize the fleet while maintaining productivity. Standard on the P-Tier ADTS are a variety of owner and operator settings. These onboard features, such as rollover protection, downhill dump protection, frame protection, hill hold, shuttle shifting and descent control are designed to help eliminate some of the operator inputs and simplify operation.
