Case Construction Equipment’s Alpha Series line of skid steer loaders now meet the Tier 4 Final emission standard with upgrades to four products. The SR175 and SV185 medium-frame skid steers use new engine technology and a diesel oxidation catalyst (DOC) solution only to meet Tier 4 Final requirements. The SR130 and new SR160 compact frame skid steers meet Tier 4 Final status using the more typical cooled exhaust gas recirculation (CEGR) with diesel particulate filter (DPF). Additionally, the large frame SR220 and SV250 skid steers move to Tier 4 Interim with CEGR and DPF technology. The SR175 and SV185 skid steers are updated with a new ISM diesel four-cylinder turbocharged and after-cooled engine with a high pressure common rail (HPCR) fuel system design and electronic controls.
The SR175 has a 21-percent higher peak torque rise at 1,800 rpm compared to the previous model, and goes from 60 to 67 gross horsepower, a 12-percent increase. The SV185 remains at 60 gross horsepower, but it has 7 percent more torque than the previous version. Operators now also have the flexibility to increase the machines’ rated operating capacities by a hundred pounds — to 1,850 pounds for the SR175 and 1,950 pounds for the SV185 — with optional counterweights.
