Features

        
  • Auto shift mode, when active, allows the machine to upshift or downshift based on machine speed and torque, optimizing performance and saving fuel.
    •     
  • The left pedal acts as a brake, transmission neutralizer and an engine decelerator to override the engine speed selected by the throttle lock. Operators can slow down when the throttle lock is engaged and to return to throttle lock without pressing a resume or set button. Helps maneuvering around trucks, tractors or other obstacles.
    •     
  • Steering and Transmission Integrated Control System (STIC™) enhances operator comfort by integrating steering and transmission control functions in a single lever. Includes finger-controlled gear selection.
    •     
  • Load sensing hydraulic steering system ensures smooth steering at all speeds and engine levels.
    •     
  • Variable displacement piston pumps enhance efficiency.
    •     
  • Steering articulates 43 degrees each direction allowing operators precise positioning for easy operation in tight areas.
    •     
  • Electro hydraulic controls help ensure responsive, predictable implement control.
    •     
  • Electronically controlled hydraulic cylinder stops deliver smooth machine operation, less stress on operator.
  • Designed and made with purpose-built structures to remain safe and durable for the long run.
  • Long-life-designs, materials and robotic welding ensure multiple life cycles and ability to withstand the toughest conditions.
  • Full box-section rear frame resists torsional shock and twisting forces.
  • Heavy-duty steering-cylinder mounts efficiently conduct steering loads into the frame.
  • Single Clutch Speed Shifting (SCSS) delivers consistent, smooth shifting and efficiency.
  • Strategic use of metallurgy and heat treating ensures long-life gears.
  • Torque converter with lock-up clutch eliminates drive losses, reduces system heat, improves travel speeds, and increases fuel efficiency.
  • Cat C15 engine is built and tested to meet your most demanding applications.
  • Two engine options are available to meet Tier 4 Final/Stage IV or Tier 3/Stage IIIA equivalent emission standards. (depending upon market).
  • Fully integrated electronic engine controls work in concert with the entire machine to make fuel go farther.
  • Engine Idle Shutdown reduces fuel waste during idling periods.
  • Delayed Engine Shutdown maximizes durability.
  • Chevron Tamping Tip Design provides greater ground pressure, more compaction, excellent traction and a smooth ride.
  • Compaction is achieved from the bottom of the lift to the top. The tapered tips walk out of the lift without “fluffing” the soil. The top of the lift is compacted and the surface is relatively smooth and sealed so hauling units are able to maintain a high speed when traveling over the fill.
  • The 825K travel speed delivers four forces of compaction: pressure, manipulation, impact and vibration.
  • This compactor also spreads fill, potentially reducing the number of spreader tractors needed for the project.
  • Symmetrical tamping tip pattern delivers equal compaction in forward or reverse. Tips are full perimeter and replaceable.
  • Two cleaner bars on each wheel keep drums free of carryover dirt, in forward and reverse, maximizing efficiency. Cleaner bars are available with standard or abrasive tips depending upon the application. Bars are adjustable and bar tips are heat-treated and direct-hardened cutting-edge steel to increase life.
  • Pressurized cab sits on isolation mounts improving comfort and reducing sound.
  • Cab features a convenient floor storage tray/lunch box.
  • Cat Comfort Series III Seat includes mid-back design, thick, contoured cushions, air suspension, six-way adjustments, and a seat-mounted implement pod and STIC steer that moves with the seat for optimal control.
  • Control panel gives operators the information and controls for safer and time-saving settings.
  • STIC control simplicity provides maximum responsiveness and control with STIC that combines directional selection, gear selection and steering into a single lever.
