The D8T is the mainstream heavy dozer of Australian mining and bulk earthworks, sitting a class below the biggest pit machines but well above general civil gear. Typical buyers are mining contractors, large civil firms and quarry operators pushing production dirt or ripping rock. Used examples are almost always set up with a semi-universal blade and single-shank ripper, and many come out of mine fleets with full guarding, fire suppression and the paperwork to match. Supply skews to the eastern mining states, and the price spread is unusually wide: tired high-hour units trade at a fraction of what late-model, low-hour or rebuilt machines fetch. Undercarriage condition, ripper wear and rebuild status matter more than build date, so component hours and service history are the first things to check.

What a Cat D8T is used for

The Cat D8T is a heavy bulldozer for mining, quarry and major civil earthmoving, including ripping hard ground.

  • Mass earthworks and bulk push
  • Mining and quarry dozing
  • Ripping rock and hard ground
  • Land clearing at scale
  • Major civil site formation

What Moves the Price

Adds the most

Undercarriage remaining

Undercarriage is the price-maker on tracked gear: a machine at high remaining percentage is worth dramatically more than the same unit run down to steel.

Clear premium

Rippers & blade spec

Multi-shank rippers and the right blade for the class widen the buyer pool and lift the price — bare-back dozers sell to fewer bidders.

The floor

Mining & fleet auctions

Bulk fleet and mine-site disposals set the floor. Civil-spec machines with history recover a clear margin over auction pricing.

Priced off the top

Powertrain hours

An engine or final-drive rebuild is a six-figure conversation on big dozers — buyers price component hours before anything else.

D8T Price FAQ

What is a Cat D8T used for?
The Cat D8T is a heavy bulldozer for mining, quarry and major civil earthmoving, including ripping hard ground.
How much does a Cat D8T weigh?
The Cat D8T has an operating weight of 39,420 kg (standard, SU blade + single-shank ripper).
What engine is in a Cat D8T?
The Cat D8T is powered by Cat C15 ACERT, 233 kW (312 hp) net.
How much is a new Cat D8T?
New Cat machines like the D8T are usually sold price-on-application rather than at a published list price, so a new Cat D8T depends on spec, options and dealer. Once you have a quote, our equipment finance calculator estimates the monthly repayment.
Where do used Cat D8Ts sell in Australia?
Mine fleets set the terms in this market. The bulk of used D8Ts come out of mining and quarry operations in the eastern states, often still wearing full guarding and fire suppression, and they arrive with the component-level records that industry keeps as a matter of course. Mining contractors and large civil firms buy them back. Machines move through Cat dealer channels and the big plant auctions, where whole fleets clear at once. The wide gap between a tired machine and a rebuilt one is the whole story: rebuild status, not build year, is the price.
What makes one D8T worth more than another?
Undercarriage percentage is the price-maker on a dozer — it is the first number a serious buyer asks for. Rippers and blade spec widen the market, fleet auctions set the floor, and component hours on the powertrain are priced before anything else.

Buying a Cat D8T

What to check before you buy

  • Undercarriage remaining life, which at this size dwarfs every other cost
  • Rebuild status on engine, transmission and final drives, with component hours
  • Ripper shank, tips and lift-cylinder condition
  • Semi-universal blade wear, cutting edges and push-arm trunnions
  • Whether mine-spec guarding and fire suppression are still fitted and certified
  • Service records, which mine fleets keep and smaller owners often do not

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 dozers travel too slowly to reliably meet the motor-vehicle test, so a clear serial search proves little. Search against the seller rather than the machine: an individual by name and date of birth, or a business by its ACN.

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