  • Backhoe: Excavating attachment mounted on rear of loader used for digging and trenching tasks
  • Boom: The main arm of a backhoe that raises and lowers the dipper stick and bucket
  • Crowd: Mechanism controlling the inward or outward movement of the backhoe bucket
  • Open-Center Hydraulic System: A hydraulic system where fluid is supplied constantly and directed via valves to specific implements.
Maintenance and Usage Tips
  • Regularly inspect hydraulic hoses and fittings for leaks or wear to maintain system reliability
  • Maintain proper engine oil and filter schedules to ensure consistent performance
  • Monitor transmission fluid levels to avoid shifting issues
  • Verify the condition of bucket teeth to maximize digging efficiency
Conclusion
The Case 680CK equipped with a 36-inch backhoe hoe presents a balanced solution for operators needing a reliable, maneuverable machine capable of precise digging and loading tasks.
