A tractor backhoe attachment turns a compact tractor into a mini excavator for trenching, footings, and general digging on a lifestyle block — this guide ranks the options sold through Implements Direct against real digging jobs, not just horsepower charts.
- Del Morino RES10 Backhoe is the best tractor backhoe attachment for lifestyle block digging in 2026, priced at NZ$10,995 for 10-35 HP tractors.
- Sierra PTO Post Hole Borer (Large) beats a backhoe bucket for round fence post holes.
- Novaquip Single Tine Ripper with Pipe Laying Attachment cuts drainage trenches without a full excavation rig.
- Novaquip Rippers for Compact Tractor at NZ$1,095 loosens compacted ground before you dig anything.
- An 18-inch auger is the budget pick for planting holes and small-diameter digging jobs.
Why this matters
Most lifestyle block digging jobs in New Zealand don't need a hired excavator — they need the right implement bolted to the back of a compact tractor. Fence post holes, drainage trenches, footings for a shed, planting holes for an orchard: each one calls for a different tool, and a backhoe attachment is only the right answer for some of them.
A true tractor backhoe attachment gives you a hydraulic digging arm on the 3-point linkage, run off the tractor's PTO or hydraulics, with enough reach to dig a trench a metre or more deep. That's overkill for a single fence post and underpowered for a job an actual excavator should handle. Getting this wrong either wastes NZ$10,000-plus on gear you barely use, or leaves you renting a digger for a job a Sierra post hole borer would have handled for a fraction of the cost.
The ranking below treats the backhoe attachment as one option among several digging tools, because that's how the decision actually plays out on a real block in 2026.
What makes the best tractor backhoe attachment
- Digging depth and reach matched to the trench or footing you're actually cutting, not the deepest spec on the page
- PTO or hydraulic horsepower requirement that sits inside your tractor's rated output, not right at the ceiling
- 3-point linkage category (Cat 1 or Cat 2) that matches your tractor's hitch
- Bucket, auger or tine width sized to the hole or trench you need, not the widest option available
- Stability under load — a rear-mounted digging arm shifts the tractor's centre of gravity more than most implements
- How often you'll actually use it versus renting or hiring a digger for one-off jobs

1. Del Morino RES10 Backhoe: best tractor backhoe attachment for deep trenching and footings
The Del Morino RES10 Backhoe is a PTO-driven digging arm built in Italy for tractors from 10 to 35 HP, mounted on the 3-point linkage. It's the closest thing to a real mini excavator you can bolt to a compact tractor, and it's the only true backhoe attachment in this lineup.
Del Morino RES10 pros:
- Digs trenches and footings a stand-alone bucket or auger can't reach
- Fits the same HP range as most compact and sub-compact tractors used on lifestyle blocks
- 3-point linkage mount means no separate loader or quick hitch required
Del Morino RES10 cons:
- At NZ$10,995 it's the most expensive item on this list by a wide margin
- Needs a tractor with hydraulic output that matches the arm's demands
- Overkill if your only jobs are fence posts or planting holes
Del Morino RES10 pricing: NZ$10,995.
Best for: lifestyle block owners cutting drainage trenches, shed footings, or pond edges who'd otherwise hire an excavator.
Verdict: Buy if you're digging multiple trenches or footings a year and want to stop paying for excavator hire on a 10-35 HP tractor.
2. Sierra PTO Post Hole Borer (Large): best for fence post holes
The Sierra PTO Post Hole Borer runs off the tractor's PTO through the 3-point linkage, driving a large-diameter auger straight down for round fence post holes. It does one job — round, vertical holes — better and faster than a backhoe bucket ever will.
Sierra Post Hole Borer pros:
- Purpose-built for round holes, so it's faster per hole than any bucket attachment
- 3-point linkage mount suits most compact tractors already running other Sierra implements
- No lateral digging arm to balance, so it's more stable on smaller tractors
Sierra Post Hole Borer cons:
- Useless for trenching or footing work — it only digs round holes
- Auger size has to match your post diameter, so check fitment before buying
Best for: fencing jobs where a backhoe attachment would be slow overkill.
Verdict: Buy if fence posts are your main digging job — a Sierra post hole borer will out-pace a backhoe attachment hole for hole.
3. Novaquip Single Tine Ripper with Pipe Laying Attachment: best for drainage trenches
The Novaquip Single Tine Ripper with Pipe Laying Attachment combines a subsoil ripping tine with a pipe-laying shoe, cutting a narrow channel and guiding pipe into it in the same pass. It's a cheaper route to a drainage trench than a full backhoe arm, at the cost of trench width.
Novaquip Ripper pros:
- Rips and lays pipe in one pass, saving a second implement change
- Mounts on the 3-point linkage like most other implements in this list
- Cheaper entry point into trench work than a backhoe attachment
Novaquip Ripper cons:
- Trench is narrower than what a backhoe bucket cuts, which limits pipe diameter
- Not suited to footings or anything needing a wide, flat-bottomed excavation
Best for: drainage runs and underground pipe work where trench width isn't critical.
Verdict: Buy for straightforward drainage runs; Hold for anything needing a wide trench or footing depth — that's the Novaquip single tine ripper with pipe layer job description, not the backhoe's.
4. Novaquip Rippers for Compact Tractor: best for breaking up compacted ground before digging
The Novaquip Rippers for Compact Tractor attachment is a multi-tine ripper sized for compact and sub-compact tractors, built to break up hardpan and compacted farm tracks before anything else touches the ground. It doesn't remove soil — it loosens it so a backhoe, auger or spade can do the rest.
Novaquip Rippers pros:
- At NZ$1,095 it's one of the cheaper implements on this list
- Sized specifically for compact and sub-compact tractors, not scaled-down from a bigger machine
- Makes hard clay or compacted tracks workable for the digging tool that follows
Novaquip Rippers cons:
- Doesn't dig a hole or trench on its own — it's a prep step, not a finishing tool
- Limited value if your soil is already loose or sandy
Novaquip Rippers pricing: NZ$1,095.
Best for: hard clay or compacted ground that stalls a post hole borer or backhoe before it's even started.
Verdict: Buy as a companion tool if your soil is heavy clay; Skip if your ground is already soft enough to dig directly.
5. 18-inch auger: best budget option for planting holes
An 18-inch auger is the simplest tool on this list — a PTO-driven bit with no hydraulic arm and no linkage complexity beyond the standard mount. It's built for round holes at planting or fence-post scale, not trenches.
18-inch auger pros:
- Simplest and lightest implement in this lineup, easy to mount and remove
- No hydraulic arm to balance, so it suits smaller sub-compact tractors
- Well suited to orchard, vineyard or shelterbelt planting holes
18-inch auger cons:
- Round holes only — no lateral digging, no trenching
- Diameter is fixed at 18 inches, so it won't suit every post or planting spec
Best for: planting jobs and smaller post holes where a full post hole borer or backhoe is more than the job calls for.
Verdict: Buy for planting-scale holes; Skip if you need anything wider or deeper than a single round hole.
“If your tractor sits at the bottom of the backhoe's rated horsepower range, the trenching job will be slower than the spec sheet suggests.”
How we ranked
Each item earned its slot against the criteria above, not against a single leaderboard. The Del Morino RES10 Backhoe wins overall because it's the only implement here that actually digs a trench or footing — everything else is ranked against a narrower job it does better than a backhoe would. Price, PTO fit, and the specific digging task decided every placement, and the rippers for compact tractor attachment sits lower because it preps ground rather than finishing a hole.
Which tractor backhoe attachment should you choose?
If you're cutting trenches, footings, or drainage lines more than once a year, the Del Morino RES10 Backhoe at NZ$10,995 is the default buy — it's rated for 10-35 HP tractors and it's the only true backhoe in this lineup. If your digging is really fence posts, buy the Sierra PTO Post Hole Borer instead and save the backhoe budget. Heavy clay ground gets the Novaquip Rippers for Compact Tractor first, as prep before anything else touches the soil. Drainage runs without a wide trench requirement suit the Novaquip Single Tine Ripper with Pipe Laying Attachment. Planting holes at orchard or shelterbelt scale suit the 18-inch auger, no backhoe required.
FAQ
What's the best tractor backhoe attachment for lifestyle block digging in 2026?
The Del Morino RES10 Backhoe is the best tractor backhoe attachment for lifestyle block digging in 2026, rated for 10-35 HP tractors and priced at NZ$10,995. It's the only true hydraulic digging arm in this category, suited to trenches and footings rather than single holes.
How much horsepower do you need for a PTO backhoe attachment?
The Del Morino RES10 Backhoe is rated for tractors from 10 to 35 HP. Sitting near the bottom of that range means slower digging, so match the tractor's rated PTO output to the harder end of your soil conditions.
Is a post hole borer better than a backhoe for fence posts?
Yes, a PTO post hole borer like the Sierra PTO Post Hole Borer digs round fence post holes faster than a backhoe bucket. A backhoe attachment is built for trenches and footings, not repetitive round holes.
Can a ripper attachment replace a backhoe for drainage trenches?
A ripper with a pipe-laying attachment, like the Novaquip Single Tine Ripper, can lay drainage pipe in a narrower channel than a backhoe bucket cuts. It's a cheaper option when trench width isn't critical.
How much does a tractor backhoe attachment cost in New Zealand?
The Del Morino RES10 Backhoe is priced at NZ$10,995 in 2026. Post hole borers, rippers and augers cost considerably less, since none of them include a hydraulic digging arm.
What's the difference between a 3-point linkage backhoe and hiring an excavator?
A 3-point linkage backhoe attachment mounts on your own tractor and stays on the property, while an excavator is hired per job. Buying makes sense once you're digging trenches or footings more than a couple of times a year.
Do you need extra hydraulics to run a backhoe attachment?
A PTO-driven backhoe attachment like the Del Morino RES10 uses the tractor's existing PTO and hydraulic supply rather than a separate hydraulic kit. Check your tractor's rated hydraulic flow matches the implement's requirement before buying.
What tractor attachment digs the cheapest holes for planting?
An 18-inch auger is the cheapest route to planting-scale holes, since it needs no hydraulic arm and mounts directly on the 3-point linkage. It's limited to round holes only, with no trenching capability.
One last thing
Most lifestyle block owners buy the backhoe attachment first and the ripper second — it should be the other way round on heavy clay. Running the Novaquip Rippers for Compact Tractor through hard, compacted ground before the backhoe or borer goes in cuts the load on both, and it's the NZ$1,095 step people skip until the digging job stalls halfway through.
