Cat 140M Grader Price Guide

A broad indicative used-price band for the Cat 140M, modelled from a sourced new price and HeavyBook’s disclosed grader depreciation curve. It is not verified sold data; age, hours and condition decide where a real machine lands.

3-year low-hour reference $289,000 Newer modelled point

This is a broad modelled estimate, not a verified market range. It starts with the sourced indicative new price of $397,000 and applies HeavyBook’s declared depreciation curve for graders at the reference ages shown above. A real machine can sit outside it because of hours, condition, attachments and location. See the method →

The 140M sits in the middle of Cat's grader range and is close to the default road machine in Australia — the model shire councils, civil contractors and rural landholders reach for when roads need building or holding together. It marked the shift from the old lever-steer generation to joystick controls, which still divides veteran operators, so confirm your operator is comfortable before committing. Used stock runs from hard-worked ex-contractor units to well-kept ex-government machines with full service history, and asking prices spread widely as a result — hours, condition and documentation matter far more than age alone. All-wheel-drive variants and machines fitted with rippers, push blocks or grade-control hardware appear regularly. Supply sits mainly along the eastern seaboard, and tidy late-model examples with provenance hold their money notably well.

What a Cat 140M is used for

The Cat 140M is a larger motor grader for highway construction, bulk grading and mine haul-road maintenance.

  • Highway and main-road construction grading
  • Bulk grading and site levels
  • Mine and quarry haul-road maintenance
  • Large civil surface and drainage grading

What Moves the Price

Adds the most

GPS / machine control

A grader wired for machine control — or sold with the kit — commands a clear premium from civil buyers who would otherwise pay to retrofit.

Clear premium

Circle & blade condition

A tight circle, straight moldboard and healthy cutting edges are the heart of a grader. Buyers pay up for one that still holds grade.

The floor

Council & fleet disposals

Shire and fleet auction disposals set the floor of the market. Dealer-reconditioned machines recover most of the gap.

Priced off the top

Hours & driveline wear

High-hour transmissions and tandem-drive wear are expensive rebuilds — buyers price them before they price the machine.

140M Price FAQ

How much is a used Cat 140M worth in Australia?
HeavyBook's indicative used-price estimate spans $91,000–$289,000, with $171,000 as the 8-year mid-life reference. The low and high points use 14-year and 3-year reference ages. This is modelled from a sourced new price and a declared category depreciation curve — not verified sold data. Age, hours, condition, attachments and location can move a real machine outside the band.
Is this estimate based on real sold prices?
No. It is a transparent modelled reference while verified sold-price data is unavailable. HeavyBook keeps it visually separate from market ranges, publishes the assumptions, and never uses it as an offer, valuation or sample-sized market figure.
What is a Cat 140M used for?
The Cat 140M is a larger motor grader for highway construction, bulk grading and mine haul-road maintenance.
How much does a Cat 140M weigh?
The Cat 140M has an operating weight of 18,991 kg (typically equipped).
What engine is in a Cat 140M?
The Cat 140M is powered by Cat C7 ACERT.
How much is a new Cat 140M?
A new Cat 140M is around $397,000 ex-GST (WesTrac's tendered supply price for a new 140M in a 2020 WA shire tender, ex-GST. Its Cat 140 successor has tendered higher since.). Used examples list for less; HeavyBook's equipment finance calculator estimates the monthly repayment on either.
Where do used Cat 140Ms sell in Australia?
Most used 140Ms in Australia surface from two places: shire and council fleet renewals, which come with documented service history and predictable maintenance, and civil contractors offloading after a project ends. Both routes reach buyers through Cat dealer trade-in stock and through the major auction houses, Grays and Pickles among them, where government disposals are listed in volume. Supply favours the eastern states and rural service centres. Ex-government machines carry a clear provenance premium, and they are worth seeking out — the paperwork usually exists, which is rarer than it should be at this end of the market.
What makes one 140M worth more than another?
Circle and moldboard condition matter most — a grader that still holds grade earns its price — and machine-control fitout adds a clear premium. Council and fleet disposals set the floor; high-hour driveline wear is quoted straight off the top.

Buying a Cat 140M

What to check before you buy

  • Circle and drawbar wear, the defining cost item on any used grader
  • Blade, cutting edge and moldboard condition against claimed hours
  • Whether grade-control hardware is factory, aftermarket or stripped out
  • Articulation joint and lean-cylinder play
  • Whether the joystick control layout suits your operator, since it divides them
  • Transmission behaviour under load through the full range

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.

Graders are self-propelled and move at road speeds under their own power, so a serial search normally applies. Search by the machine’s serial or chassis number, and search the seller as well if the serial returns nothing.

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