[MikePhua]

Machine Overview
The Case 680CK is a robust backhoe loader designed for versatile construction tasks such as digging, loading, and material moving. Renowned for reliability and ease of operation, the 680CK balances power and maneuverability for efficient site work.
Engine and Powertrain

• Equipped with the Case G188D 4-cylinder diesel engine delivering around 58 hp at 2,000 rpm
  
• Maximum torque is approximately 173 lb-ft at 1,200 rpm, providing strong low-end power for digging and lifting
  
• Power shuttle transmission system allows smooth directional changes without the need for clutch pedal operation, enhancing productivity in confined spaces
  

Loader and Backhoe Specifications

• The loader front bucket offers versatile loading capability with hydraulic circuits delivering 25 to 45 gallons per minute, powering boom, bucket, and crowd functions efficiently
  
• Backhoe features a 36-inch hoe (bucket) suitable for trenching and excavation in moderate soil conditions, balancing penetration and material capacity
  
• Four-speed power shuttle and open-center hydraulic system generate sufficient pressure (around 2,150 psi) for dependable tool operation
  
• Maximum travel speed ranges around 18 to 23 mph depending on configuration, sufficient for site relocation and short hauls
  

Dimensions and Capacities

• Wheelbase approximately 6.7 feet, contributing to site maneuverability
  
• Overall weight around 14,500 to 15,000 pounds, optimized for stability and transport
  
• Fuel tank capacity near 28 gallons supports extended operation with fewer refueling stops
  
• Tires sized typically around 11Lx16 front, 16.9x24 rear, balancing traction and flotation on various terrains
  

Hydraulic System

• Dual pump hydraulic system supplying dedicated flows for lifting and swing actions, maintaining continuous performance during repetitive cycles
  
• Hydraulics engineered for smooth and responsive operation of loader and backhoe arms for precision work
  

Operational Advantages

• The 36-inch backhoe bucket width strikes a balance between trench width efficiency and machine load capacity, suitable for utility installation and landscaping projects
  
• Power shuttle transmission enables operators to work without frequent clutch use, reducing fatigue and increasing output
  
• The 680CK’s compact size facilitates work in tight urban or rural job sites while maintaining the strength for demanding excavation
  

Terminology Explained

• Power Shuttle: Transmission feature allowing seamless forward/reverse shifting via lever or controls without clutch engagement
  
• 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. Its combination of efficient powertrain, responsive hydraulics, and compact footprint makes it a preferred choice for diverse earthmoving and construction applications.
