Good Question. And I think the answer depends on year the LK3054 was built. I do not believe Kioti was doing fabrication and marketing of Daedong backhoes when this model LK3054 was first available in 1993. Toward the end of the model life, Daedong did indeed start frame-rail mounted backhoe fabrication for the LK30 tractor line in 2001, giving two years of that model line access to Daedong backhoes.
Some tractor owners may have also built their own custom frame and rail mounting for Woods backhoes who did market backhoes for the early Kioti LK30 tractor line. At no point, did Daedong market a 3pt backhoe, but Woods certainly did.
Avoid 3pt backhoes at all cost.
