A subsoiler breaks up the compacted layer sitting below topsoil that blocks root growth and stalls drainage, and New Zealand pasture builds that layer fast under stock traffic, feeder wagons and repeat passes with the same tractor. This 2026 guide ranks the subsoiler and ripper attachments Implements Direct stocks for compact and mid-size tractors, with a straight verdict on which one earns a spot on your three-point linkage.
- Novaquip NSR0020 single tine ripper at NZ$1,695 is the best subsoiler for larger pasture blocks in 2026 - Buy.
- Novaquip NTR1200 rippers at NZ$1,095 suit compact tractors on smaller lifestyle blocks - Buy.
- Novaquip NSR0010 at NZ$895 doubles as a drainage tool but shatters less soil per pass - Consider.
- Contractor-hire multi-shank subsoilers only pay off past several hectares worked in one pass - Wait.
Why compacted pasture needs more than a harrow
A chain harrow or rotary hoe works the top 50-100mm. Compaction from stock hooves and machinery sits deeper than that, forming a hardpan that stops rain draining through and stops roots pushing past it. The result is pooling after rain, patchy pasture growth in dry spells, and paddocks that green up slower every spring.
A subsoiler, sold in New Zealand mostly as a single tine ripper, is built to run a shank below that pan and lift it without inverting the topsoil. The Novaquip single tine ripper/pipe layer is the largest version Implements Direct stocks for this job in 2026, and it sets the benchmark the rest of this list is measured against.
How we ranked these subsoilers
Implements Direct has stocked ground-engaging attachments for New Zealand conditions for over 22 years, and that experience shapes the ranking criteria here: tine design (single shank versus a multi-tine set), mounting type, price against build weight, and how each model is actually described for compaction and drainage work rather than general cultivation.
Every model below is a real product listed on the Implements Direct store as of 2026, not a lab test result. Price, mounting and stated use are pulled straight from the product listing. Where a model's specific working depth or tractor HP figure isn't published, that gap is flagged rather than filled with a guess.
The best subsoilers for compacted pasture in 2026
1. Novaquip NSR0020 Single Tine Ripper/Pipe Layer - the deep-shatter pick
This is the "big brother" version in the Novaquip ripper range, built heavier than the entry model for jobs that need more shatter per pass. At NZ$1,695 in 2026, it's the priciest single tine ripper Implements Direct stocks, and the extra weight is what buys the added shatter depth.
A ripper that only scratches the topsoil is an expensive garden fork - the point of this attachment is breaking the pan below plough depth, not tidying the surface. For larger pasture blocks with real compaction history, this is the model that does the job in fewer passes. Verdict: Buy if your paddocks run several hectares and you want fewer runs across them. Full details on the single tine ripper/pipe layer are on the product page.
2. Novaquip NTR1200 Rippers for Compact Tractor - the lifestyle-block pick
Built as a set of rippers sized specifically for smaller tractors, this one exists because lifestyle block owners kept asking for something lighter than the full-size single tine models. At NZ$1,095, it sits in the middle of the pricing spread and matches compact tractor hydraulics rather than overloading them.
Running multiple smaller tines instead of one large shank means more even coverage per pass on a smaller paddock, at the cost of the single deep shatter line the NSR0020 delivers. Verdict: Buy for lifestyle blocks under a few hectares where a compact tractor is doing the work. See the rippers for compact tractor listing for fitment.
3. Novaquip NSR0010 Single Tine Ripper with Pipe Laying Attachment - the budget pick
The smaller sibling to the NSR0020, priced at NZ$895 in 2026. It's built for exactly this job description on lifestyle blocks: breaking up compacted soils, cutting drainage channels, and subsoiling in one pass with the pipe-laying attachment doing double duty.
It won't match the shatter depth of the larger NSR0020, but for a smaller lifestyle block that also needs the occasional drainage run, the dual function earns its keep. Verdict: Consider if budget matters more than working a large area quickly.
4. Contractor-hire multi-shank subsoiler - the go-big option
Multi-shank, winged subsoilers exist as heavier contracting equipment for working large paddocks in fewer passes than any single tine ripper can manage. Implements Direct doesn't stock this category, and for most lifestyle block and small farm paddocks it's overkill anyway.
The pull requirement and transport logistics only make sense once you're working multiple hectares in one session. Verdict: Skip unless you're subsoiling at a scale that a compact tractor and a single tine ripper genuinely can't cover in a reasonable day.
“A ripper that only scratches the topsoil is an expensive garden fork - the point is breaking the pan below plough depth.”

| Novaquip NTR1200 | NZ$1,095 | Set of rippers | Compact tractors, small blocks | Buy |
| Novaquip NSR0010 | NZ$895 | Single, with pipe layer | Budget-conscious lifestyle blocks | Consider |

Where to buy a subsoiler in NZ
- Match the tine to your tractor's rear linkage capacity first. A ripper built for a compact tractor won't shatter as deep as the NSR0020, but forcing an oversized shank onto a light linkage strains the tractor, not the soil.
- Buy from a supplier that ships the attachment fully assembled and covers freight NZ-wide, so a heavy single tine ripper doesn't arrive needing extra parts sourced separately.
- Check whether the paddock also needs a drainage pass. If it does, a model like the NSR0010 that combines ripping with a pipe-laying attachment saves buying two separate implements. For general track and race compaction rather than pasture, the ripper guide for compacted farm tracks covers a related but different job.
FAQ
What is a subsoiler used for on pasture?
A subsoiler breaks up the compacted hardpan sitting below topsoil so water drains through and roots can push deeper. On NZ pasture that pan usually forms from years of stock traffic and repeat machinery passes over the same lines.
Is a subsoiler the same as a ripper?
Yes, in the New Zealand market the terms are used interchangeably for a single-tine or multi-tine shank pulled below plough depth. Implements Direct lists its 2026 range under the ripper name, and the function matches what's marketed elsewhere as a subsoiler.
How deep does a subsoiler need to go to break up pasture compaction?
Subsoiling generally targets below plough depth, roughly 300-450mm depending on where the hardpan sits. Running shallower than the compacted layer just cultivates the topsoil and leaves the pan intact.
What tractor horsepower do I need to pull a subsoiler?
It depends on tine depth, soil type and moisture, and this varies by model rather than a single fixed number. Check the specific attachment's tractor size guidance on the product listing before buying, since a compact tractor model and a heavy-duty single tine ripper are not interchangeable.
When is the best time of year to subsoil pasture in NZ?
Subsoil when the ground is dry enough to shatter rather than smear, typically late summer to autumn in most NZ regions. Working wet, sticky soil compacts it further instead of breaking it up.
Can I use a single tine ripper instead of a multi-shank subsoiler on a lifestyle block?
Yes, and for most lifestyle block paddocks it's the more practical choice. Multi-shank subsoilers are built for working several hectares in one pass, which is more machine than a small block needs.
How much does a subsoiler cost in NZ in 2026?
Single tine rippers sold by Implements Direct in 2026 range from NZ$895 for the entry model to NZ$1,695 for the heavy-duty version. Price scales with build weight and shatter depth, not brand name.
Does subsoiling need to be done every year?
No, subsoiling is not an annual job on most pasture. It's needed again only when compaction returns, which depends on stock density and how wet the paddock runs through winter.
One last thing
Run the first pass along the contour, then cross it at an angle on a second pass rather than doubling the same line. Two passes at roughly 90 degrees to each other break a wider shatter zone through the pan than one deep single pass, and it's the detail most lifestyle block owners skip the first time they run a subsoiler.
