Both Are Excellent Machines — But Parts Cost Differs
The John Deere 200G LC and Komatsu PC200-8 are two of the most popular mid-size excavators in North America, both offering excellent performance and reliability. But when it comes to parts availability and cost of ownership, there are some notable differences worth understanding before you commit to a fleet purchase.
Engine Parts
Both machines use well-supported industrial engines with strong aftermarket ecosystems. The Komatsu SAA6D107E-1 engine in the PC200-8 has an extensive aftermarket — filter kits, gasket sets, and rebuild components are widely available and competitively priced. The John Deere PowerTech 4045 in the 200G LC is similarly well-supported, with the added advantage that it is shared with John Deere agricultural equipment, meaning parts availability even in rural areas tends to be excellent.
Hydraulic Components
This is where costs diverge more significantly. Komatsu hydraulic components — pumps, motors, and cylinders — have a strong rebuilt component market, and aftermarket seal kits are available from multiple suppliers at 30–50% below OEM pricing. John Deere hydraulic parts tend to have fewer aftermarket alternatives, meaning you are more often buying OEM or paying a premium for rebuilt units.
Undercarriage
Both machines have excellent aftermarket undercarriage availability. Multiple suppliers produce track chains, rollers, and idlers for both platforms at competitive prices. This is generally the largest recurring parts cost on any excavator, so strong aftermarket availability matters significantly here — and both machines score well.
Our Verdict
Both machines offer strong parts support. The PC200-8 has a slight edge in hydraulic component availability and cost. The 200G LC benefits from John Deere's extensive dealer network and agricultural-sector parts overlap. For most buyers, the difference in parts cost over a machine life will be modest. Make your decision on work requirements, dealer relationship, and machine performance — both are well-supported platforms.
