Case Construction Equipment recently introduced a variety of improvements to its N Series loader/backhoe product line. The upgrades include the application of cooled exhaust gas recirculation (CEGR) emissions-control technology to achieve Tier IV Interim certification, as well as important improvements in performance, productivity and maintainability.
The Case 580N, 580 Super N, 580 Super N Wide Track and 590 Super N loader/backhoes now feature 3.4-L, turbocharged engines, ranging from 78 hp (58 kW) in the 580N to 108 hp (80 kW) in the 590SN. The Tier IV Interim-certified engine—with CEGR technology—burns cleaner while delivering superior horsepower, faster response and up to 4-percent better fuel efficiency under load, according to the manufacturer.
Other new standard N Series features include automatic ride control on four-wheel-drive models that engages at roading speeds to help reduce bucket spillage; and remote hydraulic test ports that allow easy, ground level access for service diagnosis to keep the machine up and running, reducing the expense associated with downtime.
Case also added a standard panel of dipper teeth on the bottom surface of the dipper, along with an optional extension/replacement pack that can expand the area of the dipper covered with serrated teeth. The dipper teeth enable the operator to secure unusually shaped or oversized pieces of debris or rock by pinning those objects against the dipper with the bottom of the bucket. The dipper teeth not only provide control of materials being moved, but they also protect the dipper from excessive wear.
