John Deere

September 28, 2010

Engineered for large-scale scraper operations, the new range of John Deere 9030-Series scraper tractors (9430, 9530 and 9630) provide horsepower ratings from 425 to 530. All three new models use a John Deere PowerTech Plus diesel engine, which features exhaust-gas recirculation, variable-geometry turbocharger, up to 38-percent torque rise and a “10-percent power bulge to bring more power and performance to the ground.” A new Vari-Cool fan runs only at speeds necessary to meet engine-cooling requirements, thus reducing horsepower draw and conserving fuel. The new tractors feature an 18F/6R powershift transmission, an AutoLoad system that, when used with John Deere scrapers, automatically varies the height of the cutting edge to match load conditions; a pair of 7-inch-diameter tapered roller bearings in the articulation joint; and a 350-gallon fuel tank.
