Ask for current stock, real machine video, specs, weight, transport size, hydraulic test and export support before quotation.
This used Doosan DX300 / 300 excavator is a practical 30-ton class crawler machine for heavier earthmoving, road work and quarry support. Before discussing price, check engine sound, hydraulic speed, undercarriage condition, real model identity and working video first.
If you are looking at a Doosan DX300 or Doosan 300 excavator, you are probably not looking for a small site machine. You want more digging capacity, more weight and stronger working stability than a 22-ton class excavator, but you may not want to pay the same brand premium as CAT 330 or Komatsu PC300. For a used excavator, the real value is not in the sticker. It is in the engine, pump response, travel strength, boom foot, swing condition and undercarriage.
This page is mainly for buyers comparing Doosan DX300, DX300LC, DX300LCA or similar 300-class crawler excavators. It should not compete with a Doosan brand collection page, a DX225 page or a DX340 / DX380 page. In the Doosan line, DX300 is for buyers who need more capacity than DX225, but still want a practical machine before moving into heavier models.
Daewoo, Doosan and Develon names may appear on machines from different periods of the same construction equipment history, but used buyers should not judge only by the badge. Machine plate, model code, machine number, weight, dimensions and real working video matter more than paint or decals.
Doosan DX300 is not simply a Hyundai 300 replacement. Hyundai 300 machines often feel more like modern Korean equipment with newer configuration and comfort positioning. Used Doosan DX300 is more of a practical, price-flexible 30-ton class machine, but the buyer must confirm whether it is a real DX300.
This model has a special market risk: some machines may be repainted or relabeled from smaller DX260-class machines, and some older Daewoo 300 machines may be dressed as newer Doosan 300 machines. A real DX300 usually costs more, so an unusually low price should be checked carefully. Do not judge only by stickers, paint, year or hour meter.
This Doosan 300 excavator specs table is for quick buyer checking, not a fixed factory promise. Final specs should always be confirmed by the current machine plate, engine plate and real working video.
| Specification Item | What to Confirm |
| Real Model Confirmation | Confirm machine plate, model code, machine number, weight, dimensions and undercarriage size |
| Model Version | DX300 / DX300LC / DX300LCA, confirm by machine plate |
| Operating Weight | 30-ton class, confirm by current machine |
| Engine | Confirm engine model by engine plate |
| Engine Power | Confirm by plate or current stock record |
| Hydraulic System | Check pump response and cycle speed by working video |
| Boom / Swing Area | Check boom foot, swing bearing play and structure condition |
| Undercarriage | Check track shoes, rollers, sprocket, idler, track frame and wear level |
| Transport Size | Confirm width, height, weight and loading method before shipment |
| Import Details | Confirm year, documents, weight and local import rules before booking vessel |
These specs matter because they affect job fit, shipping cost, import rules, trailer arrangement, loading method and final quotation. For DX300, specs also help confirm whether the machine is truly a 300-class unit.
The Doosan DX300 is for buyers who need more digging power, stability and working weight than a 22-ton DX225-class machine. It fits heavier earthmoving, road projects, quarry support and dealer customers who need a larger machine range.
For this model, real identity matters before price. Check the machine plate, model code, machine number, operating weight, dimensions, undercarriage size and working video before treating the machine as a true DX300.
A used Doosan 300 may offer a more flexible price range than some CAT 330 or Komatsu PC300 machines. But lower price only makes sense when real model identity and working condition support the quotation.
Engine sound, hydraulic pump response, travel strength and swing movement should support the price. On a 30-ton used excavator, weak hydraulics or tired travel can cost more than the money saved from a low quotation.
Boom foot, swing bearing, travel motors, track frame and undercarriage wear matter more on a 30-ton class machine than on smaller excavators. A clean repaint cannot cover weak structure or tired hydraulic response.
