3. Blade Options

   • Available with various blade configurations for versatile operations:
     • Straight Blade (S-Blade): Ideal for fine grading and leveling.
     • Semi-Universal Blade (SU-Blade): Combines the advantages of S-blades and U-blades, allowing for high material capacity and precision.
     • U-Blade: Designed for maximum material pushing.
   • Blade width and height vary depending on the configuration.

4. Transmission

   • Powershift Transmission: Offers three forward and three reverse speeds.
   • Delivers smooth and efficient power transfer to the tracks.
   • Equipped with a torque divider for better load management and fuel efficiency.

5. Ripper (Optional)

   • Rear-mounted single-shank or multi-shank ripper available for breaking hard ground and materials.
   • Heavy-duty construction for tough ripping applications.

6. Cab and Operator Station

   • Ergonomic Cab: Designed for operator comfort and safety with:
     • Climate control (air conditioning and heating).
     • ROPS/FOPS protection for enhanced safety.
     • Intuitive joystick controls for precise operation.
   • Visibility: Large windows and well-placed mirrors provide excellent visibility of the work area.

7. Hydraulic System

   • High-capacity hydraulic system for smooth and precise control of the blade and ripper.
   • Reliable and responsive performance in heavy-duty applications.

8. Cooling System

   • Advanced cooling system with efficient airflow management to maintain optimal operating temperatures during continuous use.
   • Includes a radiator, cooling fans, and thermostats.

9. Weight and Dimensions

   • Operating Weight: Approximately 80,000 lbs (varies depending on attachments and configuration).
   • Dimensions: Vary based on blade type, but the D8R is larger than the D7R, designed for heavier applications.
