EquipmentWorld.com | February 2014 15 ULTIMATE UPGRADES John Deere has upgraded their G-Series motor grader line to meet Tier 4 Final emissions standards. The 12 models in the G-Series – 670G/GP, 672G/GP, 770G/GP, 772G/GP, 870G/GP, 872G/GP – all weigh the same as their Tier 4 Interim predecessors. Diesel particulate fi lter cleaning occurs automati- cally, and the DPF can go up to 15,000 hours before ash removal. Upgrading the 220- to 287-net-horsepower G-Series allowed Deere to include improvements requested by customers. The new series includes better all-around lighting, a more modern radio, an improved rear view camera with a dedicated monitor and upgraded cab features. For 2014, a new laminated cab glass option will be available. FUEL SAVER Boost capacity while conserving fuel with the PC170LC-10 excavator from Komatsu America, which offers 5 percent more lift capacity with the standard coun- terweight than the previous model PC160LC-8, and up to 15 percent more lift capacity with an optional counter weight. The newest addition to the dash-10 series, the PC170LC-10 features operating weights ranging from 38,100 to 41,600 pounds, delivers 115 net horsepower at 2,100 rpm and is up to 10 percent more fuel effi cient than its predecessor. The excavator has an integrated design with a closed center load sensing hydraulic system that improves hydraulic effi ciency by using variable speed matching, which allows the engine speed to adjust based on the hydraulic pump output, and low speed matching, which uses a larger pump capable of producing higher pump output at lower engine speeds. The enhanced working modes match the engine speed, pump delivery and system pressure to the application. The Tier 4 Interim machine has the Komatsu Diesel Oxidation Catalyst, designed to allow soot removal with 100 percent true passive regeneration, eliminating the need for a diesel particulate fi lter. The KDOC delivers long life with no scheduled replacement interval. An advanced electronic control system better manages air fl ow rate, fuel injection and exhaust aftertreatment, which improves performance while reducing both emissions and fuel consump- tion. Komatsu's Equipment Management Monitoring System enables the operator to monitor and troubleshoot critical systems. KOMTRAX technology sends machine operating infor- mation to a secure website via wireless technology, including hour meter, location, cautions, load ratio, fuel consumption and maintenance alerts. Six working modes are available, and the excavator includes a standard rearview monitoring system.
