Komatsu Mid-Size Wheel Loaders offer great overall value, reliability and versatility. Komatsu's engine, pumps, valves, powertrain and all other major components are designed to work together to maximize efficiency and productivity. Now add the Waste Handler package which is integrated into the base tractor and you have a purpose-built machine that maximizes the amount of material you can push in all waste handling applications. Waste Handler configurations are available to meet any application and are available in as a package or as individual guards allowing you to customize your guarding package. Pair this with a pin on 6 yd³ pusher or 7 yd³ loader bucket and you have a loader that can transfer more trash. And thanks to the Tier 4 interim engine, you'll be helping the environment while you do it. A powerful Komatsu SAA6D107E-2 engine provides a net output of 142 kW / 191 HP with 10% improved fuel consumption. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified. Komatsu Variable Geometry Turbocharger (KVGT) uses a hydraulic actuator to provide optimum air flow under all speed and load conditions. Komatsu Diesel Particulate Filter (KDPF) captures 90% of particulate matter and provides automatic regeneration that does not interfere with daily operation. Increased cooling capacity ¡á Auto-reversing fan is standard ¡á Wider core coolers ¡á Standard rear screen An all new cab provides the operator with improved comfort and visibility. New high resolution monitor panel ¡á Enhanced and intuitive on-board diagnostics ¡á Integrated with KOMTRAX Level 4 ¡á Integrated with Komatsu Tier 4 technology Rearview monitoring system (standard) New high capacity air suspension seat ¡á Seat mounted EPC controls with F-N-R switch ¡á Seat heater is standard Energy saving guidance ¡á Six operator guiding messages ¡á Enhanced eco-gauge Komatsu Auto Idle Shutdown helps reduce idle time and reduce operating costs. Remote boom and bucket positioners can set kick-outs from inside the cab. Variable displacement piston pumps with CLSS help reduce fuel consumption. Large capacity torque converter with lock-up ¡á 10% lower fuel consumption ¡á Faster top speed ¡á Quick acceleration ¡á Lock-up in 2nd, 3rd and 4th gear Komatsu SmartLoader Logic helps reduce fuel consumption with no decrease in production. KOMTRAX equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.
