The 521F wheel loader offers a 12 percent increase in fuel efficiency over the E Series model, Case Construction Equipment says. The machine is available in standard Z-bar, extended-reach and tool-carrier models. Case chose selective catalytic reduction (SCR) technology for the 521F to meet Tier 4 Interim emissions standards. According to Case, SCR results in lower temperatures in the exhaust system while optimizing combustion. In addition, the 521F offers optional heavy-duty axles, enabling it to operate in scrapyards or recycling centers. The axles, with auto-locking front and open-rear differentials, have the same design as the larger F series wheel loader axles, including metal face seals and sintered-bronze brake linings.
