L/LINK ENDS FORD BIG

The big lower link end for Ford tractors is an upgraded, robust end fitting attached to the end of the lower lift arms in the 3‑point hitch system. It connects the implement to the tractor via a pin, ball, or swivel mount. The “big” spec means it accommodates larger pin diameters (bore), uses thicker material, and has reinforced mounting areas to handle greater stresses, especially on higher horsepower tractors or heavy implements.

Key features & considerations:

• Bore & Pin Size: The bore (hole diameter) is larger to suit heavier tractor/implement connections.

• Strength & Material: Manufactured from high‑grade steel, possibly forged and heat treated, to resist bending, shear, fatigue.

• Mounting Surfaces: The mating surfaces (bolt holes, flanges) are thicker and better reinforced.

• Compatibility & Fitment: Must match the width, tail dimensions, and alignment of the lower arm of the Ford tractor.

• Load Capacity: Designed for higher loads, torque, and impact forces in heavy use.

• Wear & Maintenance: The bore, pin, and mounting bolt holes are subject to wear — regular inspection and lubrication are vital.

• OEM vs Aftermarket: Many Ford tractors use standard lower link balls (e.g. C5NN557B — lower link ball Cat II, used in Ford / New Holland
