Komatsu America Corp., a leading global heavy equipment manufacturer, introduced the new PC1250SP-11 and PC1250LC-11 Tier 4 final emissions certified hydraulic excavators. These new EPA Tier 4 Final (T4F) certified models have SAA6D170E-7 engines with two Komatsu Diesel Particulate Filters (KDPF) that do not require Diesel Exhaust Fluid (DEF) or a Selective Catalyst Reduction (SCR) system.
