Kubota
We make all our couplers with high tensile ST-52 steel. 400 BHN steel can also be used if specifically requested. These couplers are available for some mini excavators (2 ton class and above) and for backhoe loaders upto 8 ton class. Most of this particular model has been sold into Australia. You will notice the safety pin which is mandatory in case the hydraulic circuit fails for some reason.
