The Yeomans L65 plows feature a two beam configuration with shanks positioned along both beams. Due to front‑to‑rear support beam(s) shanks can only be set at certain equal spacings. These are shown on the table to the left.
*In pasture work, minor variations in shank spacing caused by frame beam positions are inconsequential, whereas cropping applications require more precise, even spacings to align with defined crop rows.

The L65SJ is part of the L65 series of frames. These frames are multi-purpose and suited to Row Crop applications and general cultivation. All L65 series models can be configured as three point linkage plows, trailing models plows, or built with both capabilities if required. Front and rear beams are 65″ (1.65m). A third beam sits behind the three point linkage hitch location, giving the L65 the ability to cater for multiple wheel and shank positions.
The Yeomans Hydraulic Stump Jump Assembly use a high pressure impulse ram. If the plow point hits a rock, the resistance or “break out force” can reach three tonnes. If the rock hasn’t moved after the plow has travelled forward a few inches, the ram pressure switches to normal line pressure. This allows the breakout force to reduce to approximately one tonne. The shank then “jumps” the rock and returns to its operating position.
Yeomans Keyline Plow Frames suit a 13″ (330 mm) shank spacing. Shanks are clamped to the frame rather than being welded to it, this allows for multiple shank spacings. The fully welded frames are manufactured at the Gold Coast factory from 4″ x 4″ x ½” (102 x 102 x 12 mm) RHS. This results in high strength equipment which has 75 years of proven reliability in the field.
The L65SJ Series can be fitted with hydraulic Crumble Roller in addition to Depth Wheels but this needs to be specified at time of ordering.
Yeomans Crumble Rollers. They are a robust 26″ diameter, angle iron construction which provides a superior level of finish to your worked ground or pasture. Units are available as either Hydraulic (HYD CRUM) or Manual (XARM CRUM) depending on your requirements.
When selecting a Yeomans plow, drawbar horsepower and tractor weight are more important than engine horsepower alone.
A tractor may have sufficient horsepower on paper, but without adequate weight and traction it cannot apply that power effectively. This is especially true for compact utility tractors. For this reason, Yeomans plow selection should be based on usable drawbar horsepower.
How Many Shanks Should I Run?
Depending on soil type, compaction and tractor models, we recommend anywhere from 7-15HP per shank.
Up to 20–30 horsepower per shank may be required for initial cultivation in very compacted or dry hardpan soils. In such situations it is best to order a plow based on the standard recommendation, but start plowing with fewer shanks and re-introduce shanks as soil conditions improve.
With the above in mind, a practical starting point is to allow approximately 10 drawbar horsepower per shank.

Minimal Soil Disturbance Design
75 years of Keyline expertise, design and testing has produced the best shank and point geometry to lift and fracture compacted subsoil without inverting or mixing the topsoil.
This controlled soil‑lifting action is achieved through carefully developed shank profiles and working angles that loosen the soil profile while preserving surface structure, residue, and ground cover. The result is a precise, mechanical approach to subsoil conditioning rather than aggressive cultivation.
Advanced Shear Pin System
The shear pin acts as a sacrificial mechanical safeguard, absorbing sudden shock loads by failing under excessive force before damage can be transferred to shank, clamp and frame.
What sets the Yeomans system apart is the ingenious design which uses short pieces of off-the-shelf mid steel rod instead of expensive machined pins. Changing a Yeomans pin is quick, easy and cheap. When the shear pin breaks, the shank doesn’t fall to the ground, it remains on the frame meaning a pin change takes around 40 seconds. No spare pins? no problem, use an M8 bolt to get you working again until replacements arrive.
Interchangeable Yeomans Shank System
Built around the Yeomans Oyster Clamp Shank (OCS) system, plows support interchangeable 22″, 26″, and 31″ shanks with replaceable points and adapters.
Clamp‑mounted shanks allow fast reconfiguration, simplified servicing, and long‑term component replacement without cutting or welding. This modular system gives operators the flexibility to adapt one frame to multiple applications while protecting long‑term machinery investment.
Fully Customisable & Upgradeable Frame System
Yeomans plows are built around a highly adaptable frame system designed to accept a wide range of attachments and configurations. The frame allows coulters, crumble rollers (manual or hydraulic), depth control systems, seeders, weeders, and hilling components to be easily fitted, removed, or reconfigured to suit changing applications. Plows can be set up as a dedicated cultivator, seeder, weeder, or hiller, or configured to perform multiple tasks in a single pass.
Importantly, these options can be specified at the time of purchase or added at any stage in the future, allowing the machine to evolve over the years. This modular approach ensures long‑term flexibility, protects machinery investment, and allows Yeomans plows to be upgraded and adapted over many years of use.
Heavy‑Duty Australian‑Built Construction
All Yeomans plows feature fully welded RHS steel frames designed and manufactured in Australia for Australian conditions. Frame designs have evolved through decades of field use to withstand demanding soils, variable terrain, and long working hours.
This proven construction approach delivers strength, durability, and confidence that the plow is built to perform year after year.
