Two Case mid-frame skid steer models the radial-path SR175 and the vertical-path SV185 — will offer a diesel oxidation catalyst-only solution for Tier 4 Final emissions compliance, says Case Construction Equipment.
“This is designed to take the fear out of Tier 4,” says Tim O’Brien, brand marketing manager. (Be sure to check out our video interview with Tim below.) The models’ ISM diesel four-cylinder turbocharged and after-cooled engine has electronic controls and a high pressure common rail fuel system.
Maintenance is simplified since the engines do not require a diesel particulate filter, O’Brien adds. And by only using a DOC, Case was able to retain the same size envelope as previous machines. “They can still work in the same space, but perform like the next size larger machines.
“We know that beyond emissions compliance, customers want more capability,” O’Brien continues. The SR175 now offers 21 percent higher peak torque compared with the previous model, and has 12 percent more horsepower. “With the increased torque capacity of these HPCR engines, users should focus on torque more than horsepower,” he says.
Optional counterweights will increase both the SR175 and SV185’s rated operating capacity by 100 pounds — to 1,850 pounds for the SR175 and 1,950 pounds for the SV185.
Case also introduced two compact-frame machines, the SR130 and SR160, which meet Tier 4 Final by using cooled exhaust gas recirculation with a DPF. And the company’s larger SR220 and SV250 machines have moved into Tier 4 Interim status, retaining their 82 gross horsepower engines, but receiving a 14.2 percent increase in torque.
