1. Powerful travel system for easy transit over loose stones, and highly reliable filtration system ensure higher machine performance.
  2. The new arm interflow system more efficiently controls hydraulic fluid flow, and significant reduction of in-line resistance and pressure loss boosts fuel efficiency by about 14%*. 
  3. A work environment that is quieter and more comfortable. A cab that puts the operator first is key to improved safety.
  4. Efficient Maintenance Keeps the Machine in Peak Operating Condition.
