A stone burier is a PTO-driven rotor that tills the ground and forces surface rock below the tilth line in one pass, and picking the right one for a compact tractor in 2026 comes down to matching PTO horsepower, working width and gearbox rating to your worst paddock, not your average one.
- Sierra Stone Burier 1.65m is the best overall stone burier for compact tractors in 2026 - buy it for dedicated rock burial.
- The compact Stone Burier model suits smaller sub-compact tractors where a narrower footprint beats coverage rate.
- A gear-drive rotary hoe breaks up stony ground without full burial - use it for seedbed prep, not rock clearing.
- A box blade or chain harrow only relocates loose surface stone; neither buries rock like a dedicated burier.
- Match PTO horsepower and gearbox rating to your stoniest paddock - undersizing is the top cause of early failure.
Why this matters
Rocky ground wrecks mower blades, cultivator tines and tyres, and it is a recurring cost on lifestyle blocks and cropping paddocks across New Zealand. A Sierra Stone Burier 1.65m tackles the problem at the source by tilling the soil and pushing surface rock below the working depth in a single pass, instead of you picking stones by hand or running a separate cultivation implement first.
Buying the wrong size stone burier for your tractor is the most common and most expensive mistake. Undersize the PTO horsepower and the rotor stalls in dense clay or rock-heavy ground. Oversize the unit for a sub-compact tractor and you risk gearbox damage or an unsafe lift. The rest of this 2026 guide breaks down which stone burier - or which adjacent implement - actually fits your paddock and your tractor.
What makes the best stone burier for a compact tractor
- PTO horsepower match - the burier needs to match your tractor's rated PTO output, not just its three-point lift capacity, or the rotor bogs down in dense ground.
- Working width vs paddock size - wider units cover ground faster per pass but demand more horsepower and a heavier tractor to carry them safely.
- Burial depth control - depth adjustment decides whether stones actually get pushed under the tilth layer or just shuffled sideways.
- Linkage category and PTO speed - confirm your tractor's three-point hitch category (Cat 1 or Cat 2) and PTO speed (540 or 1000 rpm) before ordering.
- Gearbox rating for rock load - a gearbox under-built for stone impact fails long before the flails wear out.
- Wear part access - hammer flails and rotor tines take a beating in stony ground, so parts availability matters more than spec-sheet numbers.

1. Sierra Stone Burier 1.65m: best stone burier for compact tractors clearing rocky paddocks
The Sierra Stone Burier 1.65m is a rotor-driven implement that tills the top layer of soil and drives surface rock below it in a single working pass. It is built for compact tractors doing genuine paddock reclamation, not light tidy-up work. This is the model most operators mean when they search for a stone burier in 2026.
Sierra Stone Burier 1.65m pros:
- Buries rock and tills in one pass, cutting the number of implement changes on a rocky job
- 1.65m working width covers ground faster than the compact model
- Purpose-built for the job rather than adapted from a general cultivator
Sierra Stone Burier 1.65m cons:
- Requires enough PTO horsepower to keep the rotor turning under load in dense or heavily stony ground
- Wider footprint needs more headland room to turn on tight blocks
Best for: compact tractor owners clearing genuinely rocky paddocks before planting or pasture renewal.
Verdict: Buy if your paddock has enough surface rock that hand-picking or a rotary hoe alone is not cutting it.
2. Stone Burier (compact model): best stone burier for sub-compact tractors and smaller blocks
The Stone Burier uses the same burial mechanism in a narrower footprint, aimed at operators running smaller tractors or working tighter lifestyle blocks. Coverage per hour is lower. The lighter build sits within the lift capacity of more sub-compact machines, which is the whole point.
Stone Burier pros:
- Narrower footprint suits sub-compact tractors and tighter turning circles
- Same burial principle as the larger model at a lighter working weight
- Fits smaller blocks where a 1.65m unit is overkill
Stone Burier cons:
- Slower per-hectare coverage than the 1.65m model
- Still needs the tractor's PTO output matched correctly - smaller does not automatically mean lighter load
Best for: sub-compact tractor owners with smaller rocky sections who do not need wide-pass coverage.
Verdict: Buy if your tractor sits at the smaller end of the compact range and the block is under a few hectares.
3. Sierra Rotary Hoe 73 inch 1.85m Gear Drive: best for stony seedbed prep without full burial
The Sierra Rotary Hoe 73 inch gear drive is a cultivator, not a dedicated burier. It breaks up clod and surface rock at working depth to leave a fine seedbed. Gear-drive tines stand up to stony ground better than chain-drive units, but the machine is not built to press stone permanently below the tilth line.
Sierra Rotary Hoe pros:
- Gear drive handles stony ground better than chain-drive alternatives
- Doubles as a general seedbed preparation tool, not just a stone-related implement
- 1.85m width covers ground efficiently for its class
Sierra Rotary Hoe cons:
- Does not bury stone below the working layer, so rock can resurface with later cultivation
- No substitute for a dedicated stone burier on genuinely rock-heavy ground
Best for: operators preparing a seedbed on moderately stony ground who do not need full rock burial.
Verdict: Hold as your only tool if the paddock is heavily rock-affected - run a burier pass first, then finish with the hoe.
4. Sierra Box Blade 7ft: best for surface stone dragging on tracks and yards
The Sierra Box Blade 7ft grades and relocates loose surface stone rather than cultivating or burying it. It is the right tool for farm tracks, yards and driveways where stone needs moving, not tilling into the ground.
Sierra Box Blade pros:
- Adjustable blade angle for grading loose stone and material off a surface
- Handles general track and yard maintenance beyond stone work
- Simple design with few wear parts
Sierra Box Blade cons:
- Does not cultivate or bury stone - it moves only what is already loose on the surface
- Wrong tool for paddock reclamation where stone is embedded in the soil
Best for: track, yard and driveway maintenance where surface stone needs shifting.
Verdict: Skip for paddock stone burial. Right tool for tracks, wrong tool for paddocks.
5. Chain Harrow 2.5m: best budget option for post-cultivation stone tidy-up
A chain harrow is a flexible, low-cost implement that drags across the surface after cultivation and redistributes loose stone, clod and debris. It buries nothing. Treat it as a finishing tool, not a solution for rocky ground.
Chain Harrow pros:
- Low cost relative to a dedicated burier or rotary hoe
- Simple mechanical design with minimal maintenance
- Useful as a finishing pass after cultivation on lighter paddocks
Chain Harrow cons:
- No burial function at all - surface stone stays on the surface
- Not built for genuinely rock-heavy ground
Best for: light surface tidy-up after cultivation on paddocks with minor stone presence.
Verdict: Wait unless your stone problem is genuinely minor. It will not solve a real rock problem.
How this list was ranked
Every entry was assessed against the six criteria above: PTO horsepower match, working width against paddock size, burial depth control, linkage and PTO speed compatibility, gearbox rating for rock load, and wear part access. Items that do not actually bury stone - the rotary hoe, box blade and chain harrow - are ranked on how well they solve an adjacent problem, not compared head-to-head with dedicated buriers on burial performance.
Which stone burier should you choose in 2026?
If your compact tractor has the PTO horsepower and the paddock has genuine surface rock, the Sierra Stone Burier 1.65m is the default pick for 2026 - purpose-built for burial and faster over ground than the compact alternative. Drop to the compact Stone Burier if your tractor sits at the smaller end of the compact range or the block is under a few hectares. If you are prepping a seedbed rather than clearing rock, the gear-drive rotary hoe does that job better than any burier will.

FAQ
What is a stone burier and how does it work?
A stone burier is a PTO-driven rotor implement that tills the soil and forces surface rock below the working depth in a single pass. It combines cultivation and stone clearance into one operation instead of requiring a separate rock-picking step.
Is a stone burier better than a rotary hoe for stony paddocks?
A stone burier is better when the goal is putting rock below the tilth line; a rotary hoe is better for general seedbed preparation on moderately stony ground. On heavily rock-affected paddocks in 2026, a burier pass followed by rotary hoe finishing is common practice.
What size tractor do I need for a stone burier in 2026?
You need a compact tractor with enough PTO horsepower to keep the rotor turning under load in dense or rocky ground, matched to the specific model's working width. Undersizing the tractor is the leading cause of stalling and early gearbox wear.
How deep does a stone burier work?
Stone buriers work within the top tillage layer that the rotor reaches, similar in depth to a standard cultivation pass. Depth is adjustable on most models so you can match how deep the surface rock sits.
Can I use a stone burier on new pasture or only cropping ground?
Stone buriers are used on both pasture renewal ground and cropping paddocks before planting. The implement suits any ground where surface rock needs to be worked below the tilth line before seeding.
What is the difference between a stone burier and a stone fork bucket?
A stone burier is a PTO-driven implement that buries rock in the ground; a stone fork bucket is a front-end loader attachment that sorts, sieves and lifts stone already loose on the surface. They solve different stages of the same problem.
Do I need a Cat 1 or Cat 2 linkage for a compact tractor stone burier?
Most compact tractors in this size range run Category 1 three-point linkage, though it varies by tractor model. Confirm your hitch category and PTO speed - 540 or 1000 rpm - before ordering to avoid a mismatch.
How much maintenance does a stone burier need in rocky NZ soil?
Hammer flails and rotor wear parts take direct rock impact and wear faster than on a standard cultivator, so regular inspection is standard practice. Matching the gearbox rating to your worst paddock reduces load on wear parts and extends service intervals.
One last thing
Most stone burier failures are not flail wear. They are gearbox overload from matching the implement to an average paddock instead of the worst one on the property. Spec the PTO horsepower and gearbox rating against your stoniest ground and the rest of the machine looks after itself for years.
