Closing Recommendation
Both are trusted 21 to 22-tonne class excavators, so pick by your fuel worry and your digging load. Choose the Kobelco SK220 when you want the lowest fuel use, move the machine around a lot and want quicker travel, with an AC cabin and GPS as standard. Choose the Komatsu PC210LC-10M0 when you do heavy, steady earthmoving, want a bigger bucket to clear heaps faster, and need a bigger fuel tank for long shifts. Also check which brand gives faster parts and service near your site. So match the machine to your work: Kobelco SK220 for fuel saving and quick movement, Komatsu PC210LC-10M0 for more power and longer run-time.
