Own the machine that drains your own country.

The Soil-Max Stealth ZD tile plough installs subsurface drainage pipe in a single pass — hitched to a tractor you already own. Drain your wet paddocks on your schedule, not a contractor's.

Backed by Farm X Australia — our office, yard and support team in Kojonup, Western Australia.

Meet the Soil-Max Stealth ZD

A tile plough built for the farmer expecting efficiency and zero downtime.

The Soil-Max Stealth ZD lays perforated drainage pipe below the surface in one pass. It comes in pull-type and 3-point configurations, attaches to a tractor you likely already have, uses Intellislope / GPS grade control for accurate fall, and installs pipe from 65 mm up to 290 mm (2"–10"). No open trench, minimal soil disturbance, and a grade you can trust.

Instead of paying a contractor every time you want to drain a paddock, you own the tool and do it yourself — this year, next year, and across your whole farm over time.

Why own your own tile plough

The machine is the advantage.

  • Use the tractor you already own.

    The Stealth ZD hitches to a tractor you've likely already got in the shed — no need to buy a dedicated machine. (What matters is tractor weight and traction — see below.)

  • Cut out the contractor.

    With tiling, the biggest cost is usually the contractor's labour. Own the plough and that value stays on your farm — you're paying for pipe and your own time, not someone else's day rate.

  • Drain on your schedule.

    Get onto your ground when conditions are right and your calendar allows, instead of waiting in a queue for one of the few drainage contractors in your region.

  • An asset that keeps working.

    Start with your worst paddock, then keep going season after season — your whole farm, on your terms.

  • User-friendly and DIY-ready.

    Intuitive controls and straightforward operation keep the learning curve short — built for the farmer to run, not just the specialist contractor.

  • Backed by a team on the ground.

    You get more than a machine: Farm X Australia runs an office and yard in Kojonup, in WA's Great Southern, with a support team right in the country you farm.

It's about weight & traction

Forget horsepower — it comes down to tractor weight.

To pull a tile plough through the profile you need enough tractor weight for traction, not a big horsepower number. That's the main thing to match. Minimum tractor weight per configuration:

  • Pull-Type
    ~11 tonnes (25,000 lb)
    Minimum tractor weight
  • ZD1600 / 3-Point
    ~9 tonnes (20,000 lb)
    Minimum tractor weight
  • ZD1200
    ~4.5 tonnes (10,000 lb)
    Minimum tractor weight

The equipment

Built to pull easy and hold grade.

Three configurations. One family of proven grade-control tech.

Soil-Max Stealth ZD Pull-Type tile plough

Pull-Type

Deepest reach
  • Working depth up to 2 m (6.5 ft)
  • Installs 100–290 mm (4"–10") tile via quick-change poly-sided boots and shear
  • Easy single-pin hitch; single-point hydraulic hook-up
  • Proprietary down-pressure manifold — only the necessary pressure on the wing wheels, so the install isn't thrown off by surface conditions
Minimum tractor
~11 t (25,000 lb)
Soil-Max Stealth ZD1600 3-point tile plough

ZD1600 / 3-Point

Mid-weight tractors
  • Working depth 1.6 m (5.5 ft)
  • 3-point linkage, Cat 3 or Cat 4 Narrow
  • Installs 65–290 mm (2"–10") tile
Minimum tractor
~9 t (20,000 lb)
Soil-Max Stealth ZD1200 / ZD48 tile plough

ZD1200

Lighter tractors
  • Working depth up to 1.2 m (4 ft)
  • Installs 65–130 mm (2"–4") tile
  • Thinner-profile shank for easier pulling through the soil
Minimum tractor
~4.5 t (10,000 lb)

Features across the range

Zero-Deflection (ZD) grade control

The pipe exits directly below the plough's hinge point, so it won't pinch or wander off grade as the ground rises and falls.

Proprietary proportional valve

Fine, incremental adjustments to stay on grade.

Quick-change poly boots & shear

Swap to change tile size; poly sides shed dirt for an easier pull.

Intellislope / GPS-RTK compatible

The grade-control system integrates with leading RTK guidance for accurate tile placement, including RTK you may already run. (Grade-control system supplied separately.)

T1 high-tensile steel construction

Strong and light, for lower drag, less tractor wear, and long life.

Tools & add-ons

Tile cart carries the pipe reel out in the paddock with the plough. Aggregate box available for aggregate-backfilled installs.

Why drainage pays off

What owning this machine does for your paddocks.

Subsurface drainage pulls excess water out of the soil profile, so your paddocks stay trafficable, your root zone stays healthy, and your wettest country stops dragging down your average.

39–73%
Canola yield uplift
~47%
Barley yield uplift

GRDC-funded trials on waterlogged WA sites. These gains are on genuinely waterlogged ground, where water is the limiting factor. Results depend on your soil, salinity, rainfall and how the system is set up.

The ground you can't rely on now becomes ground you can — and with your own plough, you can keep improving paddock after paddock.

How it works

Three steps, your tractor.

  1. 1

    Hitch it up

    Connect the plough — single-pin hitch, single hydraulic line.

  2. 2

    Survey, then set grade

    A field survey maps the lay of the land so Intellislope / GPS grade control can hold the fall before pipe goes in.

  3. 3

    Lay the pipe

    Install in a single pass, minimal disturbance, paddock by paddock.

FAQ

Common questions.

  • It's about weight and traction, not horsepower. As a guide: the Pull-Type needs about 11 t, the ZD1600/3-Point about 9 t, and the ZD1200 about 4.5 t. Tell us your tractor's make and weight and we'll match a configuration to it.
