Unlike the previous-generation 70ZV-2, the 70Z7’s Intellitech Operating System automatically adjusts the powertrain and hydraulics to actual operating demands, making the wheel loader an all-purpose option for public works departments with machine operators of varying skill levels. The 173 hp Cummins engine uses cooled exhaust gas recirculation (CEGR) to meet Tier 4 Interim emissions requirements. Hydraulic oil-change service interval: 4,000 hrs. with KCM SuperEX46 fluid; engine-oil service interval: 500 hrs. with low-ash CJ-4 oil.
