John Deere 200C Excavator Likely Built in 2004 Based on Serial Number Range and Market Trends

[MikePhua]

The JD 200C and Its Place in Excavator Evolution
The John Deere 200C LC hydraulic excavator was introduced in the early 2000s as part of Deere’s C-series lineup, which aimed to improve fuel efficiency, operator comfort, and hydraulic precision. With an operating weight of approximately 45,000 lbs and a dig depth exceeding 22 feet, the 200C LC was designed for mid-size excavation tasks including utility trenching, site prep, and roadwork.
John Deere, founded in 1837, entered the excavator market through a partnership with Hitachi in the 1980s. The 200C LC was built during a period when Deere was refining its own identity in the excavator space while still leveraging Hitachi’s hydraulic expertise. By 2004, the 200C LC had become a popular choice among contractors in North America, with strong adoption in both rental fleets and owner-operator businesses.
Serial Number Identification and Year Estimation
The serial number 200CX504859 falls within a range commonly associated with 2004 production. Deere’s serial number system for excavators typically includes a model prefix (200C), a plant code (X), and a sequential build number. While exact year decoding requires access to factory records or dealer databases, comparison with known machines for sale and auction listings suggests that units in the 504000–505000 range were built in 2004.
Supporting indicators:

• Machines with similar serial numbers listed as 2004 models in resale markets
  
• Emission compliance labels matching Tier 2 standards introduced in 2004
  
• Hydraulic pump and controller part numbers consistent with 2004 build sheets
  
• Cab layout and monitor design matching Deere’s mid-2000s configuration
  

A technician in Georgia cross-referenced a 200CX504700 unit with dealer records and confirmed a build date of late 2003, delivered in early 2004.
Key Features and Performance Characteristics
The JD 200C LC includes:

• A 6-cylinder John Deere diesel engine rated at approximately 145 hp
  
• Variable-flow hydraulic system with load-sensing capability
  
• Pilot-operated joystick controls for smooth modulation
  
• Optional long-reach boom and arm configurations
  
• ROPS-certified cab with climate control and ergonomic seating
  

Operators appreciate the machine’s balance between power and finesse. A contractor in Alberta used a 200C LC for both trenching and demolition, noting that the swing torque and bucket breakout force were ideal for mixed-use applications.
Maintenance Considerations and Common Wear Points
By 2025, most 200C LC units have exceeded 10,000 hours. Common maintenance needs include:

• Hydraulic pump rebuilds due to internal leakage
  
• Undercarriage wear, especially track chains and rollers
  
• Swing bearing inspection for play or noise
  
• Engine injector replacement and fuel system cleaning
  
• Monitor and wiring harness repairs due to age-related degradation
  

A fleet manager in Texas implemented a 1,000-hour inspection protocol and extended service life by 30% across his C-series excavators.
Parts Availability and Cross-Reference Tips
While Deere no longer produces the 200C LC, parts remain available through:

• Authorized John Deere dealers
  
• Aftermarket suppliers specializing in Hitachi-compatible hydraulics
  
• Salvage yards with C-series inventory
  
• Online platforms offering OEM and remanufactured components
  

Cross-reference strategies:

• Use engine model number (6068T) to source fuel and cooling parts
  
• Match hydraulic pump part numbers with Hitachi ZX200 equivalents
  
• Confirm bushing and seal dimensions before ordering kits
  
• Use serial number to verify compatibility with cab electronics
  

A technician in Ohio sourced a swing motor from a Hitachi ZX210 and adapted it to fit a 200C LC with minor flange modifications.
Conclusion
The John Deere 200C LC excavator with serial number 200CX504859 was most likely built in 2004, based on serial range analysis and market comparisons. As part of Deere’s mid-size C-series, it remains a capable and serviceable machine when properly maintained. With attention to hydraulic health, undercarriage wear, and electrical integrity, the 200C LC continues to deliver reliable performance in excavation tasks. In the world of legacy equipment, knowing the year is more than trivia—it’s the key to smart parts sourcing and preventive care.
