T74 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.

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 T74 is fitted with heavy duty 7.50 x 16 (8 Ply) tyres on 5 stud Jeep rims and axles.

The T74 series is available with either a Short Drawbar (SD) or Long Drawbar (LD) configuration. Both versions share common shank spacings of 13‑inch (333 mm) and 20‑inch (500 mm), with additional even spacings available depending on frame size and drawbar geometry. As a general rule, smaller frames use the SD drawbar while larger frames use the LD drawbar, allowing the T74 range to cover a wide spread of working widths and horsepower requirements.

Manufactured from fully welded 4″ × 4″ × ⅜” RHS steel, the T74 frame is engineered for strength, rigidity, and long service life. Shanks are clamp‑mounted rather than welded, allowing flexible spacing and easy reconfiguration while maintaining structural integrity. The frame is designed to accept the full range of Yeomans Oyster Clamp shanks, including 22″, 26″, 31″, and adjustable Big‑Y shank assemblies.

The trailing drawbar is a solid welded A‑frame construction, equipped with a screw jack for parking and height adjustment, and pinned height selection to suit operating conditions. This setup provides stable tracking behind the tractor and supports accurate, repeatable depth control during operation.

For enhanced performance and finish, the T74 can be fitted with optional castoring coulter discs for pasture renovation and Yeomans Crumble Rollers, available in both manual and hydraulic configurations. These options improve surface finish, protect pasture cover, and assist with consistent depth control across varying soil conditions.

Designed and manufactured on the Gold Coast, the T74 Trailing Plow embodies over 75 years of Yeomans Keyline plow engineering, providing a strong, adaptable platform for reducing compaction, improving soil structure, and supporting long‑term productive farming systems.

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.
