POWER INCREASED IN LINE OF SCRAPER TRACTORS
John Deere has introduced a new line of large, high-horsepower tractors - the 9030 Series Scraper Tractors. These three models of tractors, ranging from 425 to 530 hp, are engineered for large-scale scraper operations, providing more power, productivity, operator comfort and cleaner burning engines that meet Tier III emissions standards.
The six-cylinder PowerTech Plus engines are designed with four valves per cylinder, exhaust gas recirculation (EGR) and a variable geometry turbo (VGT). The result is a cleaner-burning engine delivering up to a 38 percent torque rise and a 10 percent power bulge to bring more power and performance to the ground while meeting Tier III emissions standards.
A new cooling package includes the patented Vari-Cool fan drive and cooling system. The mechanical-type fan runs only at the necessary speed to meet the cooling requirements of the tractor, increasing fuel efficiency and reducing power consumption. The 18-speed PowerShift Transmission (18-forward and 6-reverse speeds) is standard equipment on the 9030 Series Scraper Tractors and is designed with enhanced, event-based shifting logic to provide best-in-class shift quality and to accommodate increased power levels.
Another industry-exclusive feature on the 9030 Series Scraper Tractors is AutoLoad, which automates the scraper's hydraulic lift functions during the loading cycle when used with Deere scrapers. Once activated, it automatically adjusts the scraper's cutting-edge height according to draft loads of the equipment without operator intervention. A key feature of all 9030 Series Tractors is a larger fuel tank, which gives the new tractors up to 33 percent greater on-board fuel capacity. Combined with the fuel-efficient engines, the 9030 Series Scraper Tractors stay on the job longer between refueling.
John Deere also builds 10 models of construction-grade scrapers, both carryall and ejector style, ranging from 15 to 21 yards. Main scraper features include quick attach front and rear hitches, ORFS hydraulic connections and components, optimum edge and floor angles for best-in-class loading and four- to six-tire design for reduced ground pressure. They also feature optional scraper brakes that pass the following standards: MSHA 30CFR/57.14101, ISO 3450, ASABE S365.6. In addition, cutting edge sections can be changed depending on loading material, and scrapers can be top-loaded, direct-loaded, loaded with AutoLoad and, in the case of the 2007 ejectors, push-loaded.
