Design enhancements for the N Series backhoe loaders include those for the drive train, hydraulics (an all-new pilot-control system), and electrical system. Also, Case has made several previously optional features standard equipment and, in addition, now offers an increased suite of factory options on these models.
The now-standard fuel-economy package includes ECO mode switches for both the loader and backhoe functions, an auto-engine-idle feature that reduces engine speed to idle when backhoe controls are not used for a set interval, and a shut-down feature that stops the engine after a set idling interval. Also standard is an engine-protection-shutdown mode, which stops the engine if coolant temperature, drive-train-fluid temperatures, or engine oil pressure exceed normal ranges. Standard electrical-system features now include a battery-disconnect switch and jump-start terminal.
According to Case, the N Series drive train has been updated for improved roading and gradeability, as well as for more pushing power under load and acceleration. New, externally adjustable Extendahoe wear pads are designed to facilitate serviceability, says Case, and to maintain tolerances for reducing strain and wear on components. Factory options now available on all N Series backhoes include new LED lights (four front, four rear, and two side), bolt-on chaff screen that attaches over the standard front grille, and bolt-on front fenders. Available for 580N and 580 Super N models are 18-inch front tires (bias ply or radial) and a heavy duty front axle.
