T74 STUMP JUMP PLOW

Frame – Manufactured in Australia from 4″ x 4″ 3/8 RHS

Hitch – The Yeomans Trailing Model plows are fitted with a heavy‑duty hydraulically adjustable Top Link incorporated into the solid steel A‑frame tow bar assembly. This system allows precise hydraulic levelling of the plow frame from the tractor cab, ensuring the plow operates dead level at the selected working depth regardless of terrain or drawbar height variation.

Optional Depth Control – Hydraulic adjustment or the award winning “Ripple Clamp” system gives 25mm (1″) incremental height adjustment and capable of variable positioning internally or externally of the frame. The T74SJ depth control system features heavy duty 7.50 x 16 (8 Ply) tyres on 5 stud Jeep rims and axles.

At the heart of the T74SJ is the Yeomans Hydraulic Stump Jump shank, which normally operates as a rigid shank for effective deep soil loosening. When an immovable obstacle such as a rock or tree stump is encountered, hydraulic pressure is automatically reduced, allowing the shank to trip, lift over the obstruction, and then return to its working position without interrupting forward motion. This system dramatically reduces downtime and makes true Keyline subsoiling possible in country that would otherwise be avoided.

As a trailing model, the T74SJ benefits from an optimal pulling angle for deep penetration and is well suited to higher‑horsepower tractors, crawler tractors, contractors, and large‑scale operations. The integrated hydraulic depth control wheel system uses self‑phasing cylinders to maintain an even working depth across the full width of the plow, even in undulating terrain.

As with all Yeomans frames, shanks are clamped rather than welded, allowing flexible shank spacing and long‑term adaptability as soil conditions and farming systems evolve. The T74SJ can be configured with a wide range of shank spacings and frame widths, making it equally effective for broadacre cropping, pasture renovation, irrigation layouts, and regenerative farming systems. Optional equipment includes hydraulic or manual Yeomans Crumble Rollers for improved surface finish and moisture retention, as well as compatibility with Yeomans seed and fertilizer delivery systems for one‑pass soil improvement.

Designed and manufactured in Australia, the T74SJ reflects more than 75 years of Yeomans engineering experience, delivering reliable performance, minimal soil disturbance, and long‑term improvements in soil structure, water infiltration, and biological activity.

Why We Prefer Drawbar Horsepower (Not Just Engine Horsepower)

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.
