Doosan DX300

Used Doosan DX300: Condition, Specs and Export Notes

Doosan DX300 should not be treated as a generic used excavator purchase. Production buyers who need more reach and bucket capacity than DX225 but still want a manageable export size. Doosan buyers often look for value, but pump response, final-drive noise and swing performance still need to be checked before deposit.

Doosan DX300 is a high-capital crawler purchase; boom structure, pump health, track groups and loading plan deserve more attention than paint. It is often compared with Doosan DX225 for the smaller step and Doosan DX340 when more reach, weight or capacity is needed. Deposit decisions should wait until the seller shows the machine moving, digging under load and holding the boom without obvious drift.

Where the Doosan DX300 Makes Commercial Sense

Doosan DX300 can be a strong production machine, but export buyers need evidence on structure and hydraulics before committing funds. Typical work includes large trenching, quarry support, heavy loading, earthmoving and road construction.

Export cost changes fast when track wear, repainting, missing attachments or port distance are discovered after the first quote. Buyers need exact-machine photos, videos, hours and shipment cost before deposit.

Used-Unit Checks Before Deposit

Pump and valve wear, structural cracks, swing bearing, final drives, track frame, hydraulic oil condition and loading width. Ask for cold-start footage, hydraulic cycle video, swing and travel video, undercarriage close-ups and a clear meter-panel photo.

Ask for the machine turning, digging under load, traveling in both directions and holding the boom still. Fresh paint and still photos cannot prove pump response, final-drive noise or linkage play.

Quote Checklist Before Payment

• Confirm the exact Doosan DX300 year and meter photo before quoting.
• Match the bucket, breaker lines and coupler to the buyer’s first job.
• Check undercarriage close-ups instead of relying on repaint quality.
• Compare inland freight, port handling and ocean freight before deposit.
• Record cold-start smoke, idle sound and hydraulic cycle speed on video.
• Verify the 29,000 kg reference against the actual nameplate when possible.
• Review pump and valve wear during live video inspection.
• Separate optional repainting, spare bucket and spare parts from the base FOB quote.
• Hold final payment until loading photos and shipping documents are confirmed.
• Ask whether the stock unit includes manuals, extra attachments or service records.
• Photograph the serial plate and engine plate when the buyer needs import files.
• Note any oil leak, welded repair or missing guard before the proforma invoice is issued.

Reference Specs for Quote Comparison

Use these fixed model references for comparison only. Confirm stock-specific year, hours, bucket set, cosmetic condition and service history from the actual available unit.

Estimated FOB Price and Next Step

Estimated FOB reference: US$38,000-45,000. This is a B2B used-machine reference range, not a checkout price. Final quotation depends on year, hours, undercarriage condition, attachment package, repainting request, current stock and destination port.
