Four new Series II Articulated Dump Trucks from John Deere come with onboard weighing systems and tire-pressure monitoring systems as standard equipment along with Tier 3-certified engines and the requisite cab upgrades. Mirror-mounted lights alert the loading operator when the truck is nearing capacity, and JDLink records payload weights (the JDLink Ultimate telematics package is also standard equipment). Deere says its new fully automatic transmission with integrated retarder improves transmission shift performance and reduces fuel consumption. The 250D and 300D have dry disc brakes and axles with limited slip differentials, while the 350D and 400D have controlled traction differentials and wet disc brakes standard.
