For most landscaping and trenching, a mini excavator needs three tools: a narrow digging bucket sized to the trench, a wide smooth-edged grading bucket for shaping and cleanup, and a thumb for rock, roots and brush. Add an auger only if you drill post or planting holes — and only when the machine's auxiliary hydraulic flow sits inside the auger's published range.
Everything else — breakers, rakes, tilting buckets — is a second-season purchase. Buy the three that cover the work you already have, run them for a season, and let the jobs you turn down tell you what to add.
Match each job to a tool
| Job | Tool | What decides the size or type | Needs auxiliary hydraulics? |
|---|---|---|---|
| Irrigation, drainage or utility trench | Narrow digging (trenching) bucket | The trench width the job calls for | No |
| Footings, planting beds, general digging | Digging bucket with teeth | Soil, frost and rock content | No |
| Shaping slopes, cleaning ditches, finish grade | Wide grading (ditch-cleaning) bucket with a smooth edge | How much finish work you do | No |
| Placing rock, pulling roots and stumps, handling brush and landscape block | Thumb, working against the bucket | Mechanical or hydraulic, and the bucket widths it must close on | Mechanical: no. Hydraulic: yes |
| Post holes, planting holes | Auger (drive unit plus bit) | The drive's flow and pressure range, then bit diameter | Yes |
| Backfilling and spreading | The machine's own blade | — | No |
The pattern in the last column matters. Buckets and a mechanical thumb are a mounting question only. Anything with a hydraulic motor or cylinder is also a flow question, and that is where a mini excavator purchase goes wrong.
Buy in this order
- A digging bucket that matches your trenches. A bucket wider than the trench you need means more spoil to move, more backfill and more restoration on a finished lawn. If most of your trenching is irrigation or drainage, buy for that width first.
- A grading bucket. The smooth edge and width are what make finish work and ditch cleaning fast. It is the tool that turns a digging machine into a landscaping machine.
- A thumb. A mechanical thumb is set in position and adjusted by hand: simpler, with nothing to plumb. A hydraulic thumb opens and closes from the seat, which pays off when you handle rock and brush all day, but it needs a hydraulic circuit to the stick. Either way, it has to close cleanly on the buckets you actually run.
- An auger, last — after the flow check below.
A quick coupler changes how often you swap tools, but only if every bucket, thumb and auger matches its interface. ArcPath's excavator page states that AX excavators support buckets, augers, breakers, grapples and more through standard couplers; confirm the coupler on your machine before ordering any tool.
The flow check, with ArcPath AX numbers
Hydraulic flow is the one to measure, not estimate. Too little and the tool runs slowly and stalls under load; too much and you generate heat, which shortens a hydraulic motor's life. ArcPath's published auger asks for 7.9–13.2 gpm (30–50 L/min) at a maximum pressure of 3,046 psi (21 MPa). Here is how the three AX excavators sit against that range, using the auxiliary flow published on ArcPath's comparison page:
| Model | Width | Max dig depth | Aux hydraulic flow | Against the auger's 7.9–13.2 gpm range |
|---|---|---|---|---|
| AX-18 | 39 in (990 mm) | 7' 7" (2,310 mm) | 7.5 GPM | Below the bottom of the range |
| AX-26 | 61 in (1,549 mm) | 9' 4" (2,845 mm) | 12.2 GPM | Inside the range |
| AX-35 | 67 in (1,702 mm) | 9' 7" (2,915 mm) | 16.5 GPM | Above the top of the range |
Two cautions. First, ArcPath's published auger lists mini track loader as its carrier family; on an excavator, the combination goes through ArcPath's fitment review — mount, interface, hydraulics and application — before anything is recommended. Second, the published flow is a starting point: if a machine has been re-plumbed, confirm what is actually available at the couplers.
Which AX fits which landscaping job
- AX-18 — gates, side yards and finished properties. At 39 in wide with zero tail swing, a hydraulic retractable undercarriage, boom swing and an adjustable blade, it is the narrowest of the three and the one to take through a residential gate. Its 7.5 GPM sits below the published auger range, so treat drilling as a separate question rather than assuming it.
- AX-26 — the middle ground. ArcPath describes it as balancing power and compactness. It digs to 9' 4" (2,845 mm), and its 12.2 GPM falls inside the published auger range.
- AX-35 — deeper, heavier digging. The deepest dig (9' 7", 2,915 mm) and longest reach (17' 2", 5,225 mm) of the three, and the highest auxiliary flow. At 67 in wide, it is not a narrow-gate machine.
When none of these is the right answer: if the trench must go deeper than 9' 7" (2,915 mm), none of the AX models reaches it. If the job is long, narrow irrigation runs across a finished lawn, a mini track loader with a trencher is the other way to cut it — ArcPath lists a trencher among the ATL-1000 track loader's compatible attachments. And ArcPath does not currently publish excavator buckets or thumbs on this site: buy those matched to your machine's pins or coupler, and use Find My Fit to have ArcPath review any combination that involves its attachments.

Frequently asked questions
What attachments do I need for a mini excavator to do landscaping and trenching? Start with a narrow digging bucket sized to your trenches, a wide smooth-edged grading bucket for shaping and cleanup, and a thumb for rock, roots and brush. Add an auger only if you drill post or planting holes, and only after confirming the machine's auxiliary flow sits inside the auger's published range.
Do I need a hydraulic thumb, or will a mechanical thumb do? A mechanical thumb is set in position and adjusted by hand, with nothing to plumb. A hydraulic thumb opens and closes from the seat, which helps when you handle rock and brush all day, but it needs a hydraulic circuit to the stick. Either type has to close cleanly on the buckets you run.
Can an ArcPath AX-18 run an auger? Not with the published ArcPath auger as a given. The AX-18's published auxiliary flow is 7.5 GPM, below the 7.9–13.2 gpm range published for ArcPath's auger, and that auger lists mini track loader as its carrier family. Send the combination through Find My Fit rather than assuming it.
Which ArcPath excavator is best suited to landscaping? The AX-18 suits tight access, at 39 in wide with zero tail swing. The AX-26 balances power and compactness, with a 9' 4" (2,845 mm) dig depth and 12.2 GPM auxiliary flow. The AX-35 digs deepest of the three, at 9' 7" (2,915 mm), but at 67 in wide it is not a narrow-gate machine.
Do ArcPath attachments fit a mini excavator? Every attachment published on this site lists mini track loader as its carrier family. ArcPath also selects attachments for excavators and other carriers, with the specific combination reviewed before order — mount, interface, hydraulic flow and pressure, and the work itself.
Do I need to locate utilities before trenching or drilling? Yes. Have buried utilities located before you dig; the Click Before You Dig portal routes you to the locate service for your province.
