Search data still clusters around 1.5 tonne mini excavator, 1.8 tonne excavator for sale and 2 tonne mini excavator — and for good reason. That band is where most Australian landscapers, owner-builders and small civil crews find the balance between access and output. This size guide is a buying tool, not an operator manual: it maps real Achilles models in the ~1.4–2.1 t window to jobs, gates and budgets so you shortlist before you hit the yard.
Compare live stock on mini excavators for sale, then use the decisions below to pick one tonne class — not three.
Why the 1.5–2 t band dominates Australian yards
Access without giving up dig depth
Sub-1.5 t machines shine in the tightest courtyards. Once your gates open a little wider and trenches get deeper, the 1.5–2 tonne class pulls ahead on breakout, lift and attachment options. In our experience working with Australian landscapers, crews who “almost” outgrew a 1.2 t digger within six months usually should have started at ~1.8–2.1 t.
Trailer-friendly for multi-site weeks
Most dual-axle plant trailers in this market are built around compact diggers. A ~2 t machine still moves between Brisbane suburbs or Sydney jobs without booking a low-loader every time — a practical reason the 2 tonne mini excavator search stays hot in 2026.
Clear price step from entry models
On the Achilles floor, jumping from the A14SE (~$19,990 Inc. GST) into the A18/A22 band (~$29,990–$33,990 Inc. GST) is a real cheque — but it is still far below a 3.8–6 t workhorse. You buy capability, not vanity.
Achilles models that sit in the 1.5–2 t buying window
Weights and prices are indicative Inc. GST from the mid-2026 catalogue. Confirm before purchase.
Just under / at the 1.5 t edge
- A14SE — Yanmar 3TNV70, 20.8 hp, 1,400 kg, 0.028 m³, from $19,990 Inc. GST. Closest Achilles answer when someone insists on a “1.5 ton” search but needs a true compact footprint. Ideal for residential trenches, pool surrounds and narrow side access.
Core 1.8–1.9 t picks
- A18SE — Yanmar 3TNV70, 1,900 kg, 0.045 m³, from $29,990 Inc. GST. The volume all-rounder for landscaping and light civil.
- A18LG (SDLG) — Kubota D902, 23.5 hp, 1,840 kg, 0.04 m³, from $29,990 Inc. GST. Same price band as the A18SE with a Kubota diesel — useful if your workshop already stocks Kubota filters.
These two are the models to demo first if your Google history is full of 1.8 tonne excavator for sale queries.
Top of the “2 tonne” shortlist
- A22LG (SDLG) — Yanmar 3TNV80F, 23.9 hp, 2,100 kg, 0.04 m³, from $33,990 Inc. GST. When buyers say they want a 2 tonne mini excavator, this is the Achilles unit that usually wins the side-by-side — more mass and daily production than the A18 class without jumping to the A26S at 2.65 t.
Australian contractors typically find that once they clear 2.1 t, trailer choice and soft-ground flotation start to matter as much as dig depth. Plan the float with the machine.
Which size fits which job
Stay near 1.4–1.5 t when…
- Gates and side paths are genuinely narrow
- Most work is residential landscaping or short utility trenches
- You will float the machine yourself on a lighter trailer
- Budget caps near $20k Inc. GST
Choose the A14SE and resist “upsizing for pride.”
Choose ~1.8–1.9 t when…
- You dig several days a week across different sites
- You need a larger bucket and better truck loading than a 1.4 t can give
- You want Yanmar or Kubota serviceability without a 3 t+ float bill
Shortlist A18SE and A18LG, then pick on engine preference and cab feel at the yard.
Step to ~2.1 t when…
- Soft clay, deeper footings or heavier attachments are weekly, not rare
- Two operators will share the machine across a small crew
- You already know a 1.5 t felt underpowered on the last hire
Demo the A22LG before you look at the A26S / A38S workhorses.
What to check before you pay — size-specific checklist
- Gate and float width — measure the tightest opening on your most common site.
- Dump height — will you load high-sided trucks or only trailers?
- Attachment list — hitch, trench bucket, mud bucket, thumb; see excavator attachments.
- Hours per week — occasional weekend dig ≠ daily production; size for the heavy week, not the average week.
- Finance timing — if you need approval first, start on the finance page, then book the yard visit.
When you should leave the 1.5–2 t band
- Step down to the A12SE (~1.2 t, from $12,990 Inc. GST) only for ultra-tight access or lightest residential work.
- Step up to A26S / A38S / A60LG when truck loading, dam work or continuous civil production is the weekly norm — not “maybe one day.”
We will tell you if a skid steer fits better for your surface and access — Achilles does not sell skid steers, so you will get an honest redirect rather than a forced digger sale.
Indicative 2026 price anchors for this size band
Treat these as orientation numbers, always confirm live:
- A14SE — from about $19,990 Inc. GST (edge of the “1.5 t” search)
- A18SE / A18LG — from about $29,990 Inc. GST (core 1.8 tonne excavator for sale answers)
- A22LG — from about $33,990 Inc. GST (what most buyers mean by 2 tonne mini excavator)
Add hitch, buckets and trailer on top. A job-ready mid-compact package often lands in the low-to-mid $30ks before finance. If cashflow is tight, start the finance conversation before you fall in love with a cab on the yard.
Attachments that change whether 1.8 t is “enough”
Size is not only tonnes. A quick hitch plus trench and mud buckets turns an A18 into a daily earner; without them you will keep borrowing gear. Thumb grabs matter for demolition spoil and timber. Augers and hammers push hydraulic demand — if those tools are weekly, bias toward the A22LG rather than forcing an A14. Build the attachment list with the digger from excavator attachments so the first invoice matches the first job.

Side-by-side questions to ask on the yard
Sit in the A14SE, then the A18SE or A18LG, then the A22LG. Ask yourself: Can I see the trench line and the swing radius clearly? Does the auxiliary plumbing match the attachments I already own or plan to buy? Will this undercarriage and track width cope with my softest regular site? Is the trailer I own actually rated for this operating weight with fuel and a full bucket of mud?
Bring gate measurements and a photo of your tightest access. Sales conversations go faster when the constraint is on the phone screen, not guessed. If two models feel equal in the cab, pick on engine preference (Yanmar vs Kubota), attachment readiness and which unit is in stock for your state — not on a brochure tonne label alone.
How this guide differs from a generic “what is a mini excavator” article
This page exists to help you buy in the 1.5–2 t window. It maps search phrases like 1.5 tonne mini excavator and 2 tonne mini excavator to stocked Achilles SKUs, prices Inc. GST and job fit. It is not a how-to-operate tutorial. When you are ready, the next click should be the mini excavators for sale category or a call to book Kingswood / Archerfield — not another encyclopedia tab.
FAQ — 1.5–2 tonne mini excavator sizes
Is a 1.5 tonne mini excavator enough for landscaping?
For many residential landscaping and short trench jobs, yes — especially the A14SE class. If you load trucks daily or run heavier attachments, move toward the A18–A22 band instead of stretching a 1.5 t past its comfort zone.
What Achilles model matches “1.8 tonne excavator for sale” searches?
Shortlist the A18SE (~1.9 t) and A18LG (~1.84 t). Both sit near $29,990 Inc. GST in the current catalogue — confirm live pricing when you enquire.
Is a 2 tonne mini excavator harder to trailer?
Usually still practical on a dual-axle plant trailer, but check your trailer’s rated capacity and ramp angle. The A22LG at ~2.1 t is the Achilles unit most buyers mean when they say “2 tonne.”
Should I buy attachments with the digger?
Yes for hitch and core buckets. Ordering them with the machine from excavator attachments keeps the first job on schedule.
