Designed From the Soil Up
Not Copied from the Surface Down
For more than 70 years, Yeomans Plows have been purpose‑built to do one thing exceptionally well: Improve soil structure, fertility, and water management with the least possible disturbance.
Developed from the pioneering work of P.A. Yeomans and the Keyline System, the Yeomans Plow is not a modified ripper or a dressed‑up chisel plow. It is a dedicated soil‑building implement, refined over decades of real‑world use across thousands of farms and more than 50 countries.
The Thinnest Shank for the Least Ground Disturbance
At the heart of every Yeomans Plow is the thinnest working shank in its class.
-
- A thinner shank displaces less soil, reducing surface heave and pasture damage
- Soil is lifted and fractured, not blown apart or inverted maintaining the living ecosystem
- Existing roots are flexed, not torn out, allowing plants to recover rapidly
The result is the classic Yeomans effect: the ground rises gently behind the shank and then settles back — softer, aerated, and biologically active — while the surface remains largely intact.
Correct Shank and Point Angles — So the Plow Stays in the Ground
The relationship between shank angle and point angle is critical, and it is one of the most misunderstood aspects of subsoil plow design. Many of our competitors are yet to understand this.
Yeomans shanks and points are engineered to:
- Pull into the soil, not climb out of it
- Maintain consistent working depth
- Eliminate the “lifting” and “porpoising” common in many competitor plows
This geometry has been refined continuously for over 50 years, ensuring:
- Better soil engagement
- Reduced draft spikes
- More even fracture patterns
- Less wear on both tractor and plow
In short, Yeomans Plows work with gravity and soil forces, not against them.
Massive Breakout Force — Where It Matters
Despite their slender profile, Yeomans shanks are extraordinarily strong.
A standard 26″ Yeomans shank delivers a breakout force of over 5.5 tonnes, allowing it to:
- Penetrate compacted layers reliably
- Maintain depth in hard or variable conditions
- Fracture deep compaction without excessive surface damage
This combination — thin profile with extreme strength — is one of the defining reasons Yeomans Plows outperform heavier, cruder designs.
The Ingenious Yeomans Shear Pin System
Protection systems are often overlooked — until they fail.
Yeomans use a simple, proven shear pin system that:
- Protects the frame and shank from shock loads
- Uses low‑cost, readily available steel bar for pins
- An M8 bolt can be used as a temporary fix to keep you working or cut your own bar
- Costs a fraction of to replace compared to machined pins used by others
Can be replaced in minutes, in the paddock
The Strongest and Most Practical Depth Control System Available
Depth control is not an accessory on a Yeomans Plow — it is a core system.
Yeomans depth control systems are:
- Exceptionally robust and durable
- Simple to adjust in seconds
- Weight and forces are spread over 10 splines, not a single bolt or pins.
- Designed to hold depth consistently across varying ground conditions
Uses easily sourced components such as Holden rims
The Most Advanced Stump Jump System Available
Yeomans’ Hydraulic Stump Jump system is unmatched in both design and performance.
Unlike systems that rely on shared pressure or mechanical trip arrangements, each Yeomans stump jump shank is fitted with its own hydraulic actuator.
This delivers real advantages:
- Each shank reacts independently to obstacles
- Immediate lift over rocks, roots, or buried timber
- Rapid, controlled return to working depth
- Reduced shock loads on the frame
- Superior protection in “uncultivatable” country
For contractors and farmers working variable or marginal land, this system turns problem paddocks into productive ground.
Points Designed to Work — Not Wear Out or Ride Up
Yeomans points are not generic wear parts.
They have been continually refined over more than five decades to:
- Stay engaged in the soil
- Resist lifting under load
- Produce optimal soil fracture
- Wear evenly and predictably
- Deliver long service life
- Points are reversable. If your point gets a flat spot at the tip, simply turn it upside down to even the wear and extend its durability.
- Reasonably priced wearparts. We won’t take advantage of you once you’ve bought our plow.
This refinement ensures that the plow works better for longer, with lower lifetime cost and more consistent performance season after season.
A Modular Frame That Grows With Your Operation
A Yeomans Plow is not just a plow — it is a platform.
Frames are designed to accept a wide range of factory‑engineered options, either at time of order or retrofitted later, including:
- Weed knives
- Disk coulters
- Disc hillers
- Wedge hillers
- Seeding systems
- Liquid fertiliser systems
- Chisel plow points
- Crumble rollers
This modularity allows farmers to adapt their plow to changing crops, soils, and farming systems — without replacing the machine.
Proven Worldwide — Built In Queensland
Yeomans have sold thousands of plows into more than 50 countries, operating across:
- Pasture renovation
- Broadacre cropping
- Orchards and vineyards
- Sugar cane
- Market gardens
- Regenerative and low‑input systems
Manufactured in Australia with heavy‑section steel and uncompromising build quality, Yeomans Plows are widely regarded as the most durable soil‑improvement plows available.
The Experts — Not the Imitators
Many plows look similar at first glance. Very few perform the same in the ground.
Yeomans Plows are:
- The original Keyline plow
- Designed by soil builders, not marketers
- Refined through decades of real‑world use
- Backed by unmatched technical knowledge and experience
