More Power With Deere's New Scraper Tractor
John Deere is enhancing its Scraper Special Series Tractor lineup, including the 9620R, its largest model to date. Four wheel models and three tracked models are available.
The 9570R (570 hp), 9570RT (570 hp), and the 9620R (620 hp) feature a Cummins QSX15 Final Tier 4 diesel engine, while the 9470R (470 hp), 9470RT (470 hp), 9520R (520 hp), and 9520RT (520 hp) are equipped with a John Deere PowerTech 13.5L PSS Final Tier 4 engine. These new models include industry leading 115 GPM flow for increased hydraulic response when operating multiple scrapers.
The updated scraper tractors feature Efficiency Manager, which automatically adjusts and matches the performance of the engine and transmission to maintain ground speed with the lowest RPMs to dramatically reduce operator fuel consumption.
HydraCushion suspension offers contractors the ability to virtually eliminate road lope associated with high transport speeds typically seen on haul roads. By eliminating the lope from the ride, both loaded and empty cycle times can increase.. To further enhance ride quality and stability in high-speed transport where these tractors typically operate, all 9R wheeled scraper tractors have a 17 inch increase in their wheelbase.
To accommodate higher horsepower and larger loads, the 9R tractors’ front frame strength was increased by 10 percent and the rear frame assembly strength by 30 percent. To further support the loads of larger scrapers and reduce axle loading the short drawbar support is now standard equipment on all scraper special tractors, with the long support still being available on wheel tractors.
The tractors are equipped with AutoLoad, which controls the scraper’s hydraulic-lift functions during the load cycle by automatically adjusting the blade height until the pan is full, then disengages through normal operation.
Fuel tank capacity was increased to 400 gallons. Auto differential lock was added to the 9R Series and provides automatic traction throughout the entire jobsite.
Inside the cab, Active Command Steering was added for greater high speed control and improved low speed maneuverability. By controlling the steering inputs electronically it reduces the fatigue on the operator and keeps the tractor headed straight down the haul road with minimal correction.
