The SH235X-6 is Sumitomo's reduced-tail-swing machine at the heavier end of the mid-size excavator class, sold and supported in Australia through Tutt Bryant. It suits civil and utility contractors working road corridors, rail and urban infrastructure where a full-size counterweight won't fit inside a lane closure. Used examples along the eastern seaboard typically arrive from civil fleets, most commonly on steel tracks with a hydraulic quick hitch, auxiliary plumbing for a hammer or tilt attachment, and often a dozer blade. Supply is thinner than for the equivalent Cat, Komatsu or Kobelco, so pricing spreads widely with hours and condition rather than tracking a tight benchmark. Buyers rate the Isuzu engine and smooth hydraulics; dealer support is concentrated near capital cities, worth weighing for remote operators.

What a Sumitomo SH235X-6 is used for

The Sumitomo SH235X-6 is a twenty-tonne-plus excavator for large-scale civil, road and production earthworks.

  • Mass excavation and bulk earthmoving
  • Major civil and road construction
  • Subdivision and infrastructure works
  • Deep basement and trunk drainage
  • Production truck loading
  • Quarry and pit support

What Moves the Price

Adds the most

Hitch + bucket set

A hydraulic hitch with a proper bucket set is the single biggest add. Machines sold bare consistently land at the low end of the range.

Clear premium

Low hours for age

Well under average annual hours reads as a weekend machine. Buyers pay a visible premium over the same year at contractor hours.

The floor

Auction vs dealer

Auction is the floor of the market. Dealer and private sales recover most of the gap — at the cost of time and effort.

Priced off the top

Tracks & condition

Worn rubber tracks and tired pins get quoted straight off the asking price — buyers price the fix before they price the machine.

How much is a new Sumitomo SH235X-6?
New Sumitomo machines like the SH235X-6 are usually sold price-on-application rather than at a published list price, so a new Sumitomo SH235X-6 depends on spec, options and dealer. Once you have a quote, our equipment finance calculator estimates the monthly repayment.
Where do used Sumitomo SH235X-6s sell in Australia?
Civil fleets are the source. Machines come off road-corridor, rail and urban infrastructure work when a project finishes, and reach buyers as Tutt Bryant trade-ins or through the general plant auction houses; very little of this class passes through private hands. Supply is thinner than for the equivalent Cat, Komatsu or Kobelco, so two machines of the same age and hours can carry very different asking prices without either seller being unreasonable. Location matters as much as condition here: dealer support clusters near the capitals, worth weighing before buying one to work remotely.
What makes one SH235X-6 worth more than another?
Hours for age matter most, then attachments — a hydraulic hitch with a proper bucket set lifts the price, and machines sold bare sit at the low end. Track condition, service history and where it sells (dealer, private or auction) move the rest.

Buying a Sumitomo SH235X-6

What to check before you buy

  • Undercarriage remaining life on the steel tracks, the largest single cost item at this weight
  • Slew ring play, checked with the boom out at full reach
  • Quick-hitch condition and whether the bucket set matches it
  • Hammer and tilt circuits, and whether the plumbing was done properly
  • Isuzu engine service records, particularly on machines out of continuous fleet use
  • Dozer blade wear if fitted, and whether it was used as a blade or a stabiliser

Check it is not encumbered

A search shows whether someone else has registered a security interest over the machine — a financier who can repossess it after you have paid the seller — and whether it has been reported stolen or written off. It does not tell you what is owed, and it is not a valuation.

Tracked excavators sit right on the boundary of the motor-vehicle test, so do not rely on a serial search alone. Run both searches — by serial or chassis number, and against the seller.

Search the Personal Property Securities Register. The register publishes a case study on buying heavy construction equipment privately.
