John Deere 270 LC

The number itself roughly sorts machines by size: the low number 110 denotes compact and mini excavators, mid-range ones like 370 or 490 the classic construction excavator, and high three-digit numbers like 790 or 990 the large-class machines. Part of the lineup grew out of a cooperation with Hitachi – parts sources document structurally identical cylinders for several of these size classes shared with comparable Hitachi excavator models, evidence of shared technical roots.

Trailing letters like D, E or LC mark generation or configuration – LC denotes an extended undercarriage variant with a larger footprint for soft ground. According to the database, engine power across the whole group ranges from 48 to 396 kW and operating weight from 7,335 to 84,311 kg, clearly showing the span from compact to large excavator.

When buying used, what matters most on excavators this size is the condition of the undercarriage and track tension, the tightness of the boom and arm cylinders, and any cracks on the boom or slew ring – repairs to the slew ring or final drives are among the costliest follow-up jobs.

In short, at John Deere the model number itself reads as the size class, and the letter after it as an equipment or generation marker – a 990 and a 110 therefore share little beyond belonging to the same database line.
