The models were shipped from South Korea to the Argo base in Italy where they are kitted out with European-specification wheels, tyres and hitches.
According to Argo, which produces tractors from 35hp to 225hp at its manufacturing complex in Fabbrico near Milan, there is a good fit between the two companies.
A representative said: "In choosing Daedong as our partner for a range of compact and utility tractors spanning 22hp to 91hp, we have teamed up with a leading manufacturer in its sector."
"Argo Tractors is no stranger to OEM agreements with manufacturers - it already produces its own compact and track-laying tractors for two other makes."
Ray Spinks, AgriArgo UK general manager and sales director, said the new ranges will benefit from the after-sales support resources both Argo and Daedong.
"Apart from spares stocked by our local Landini and McCormick dealers, we have added the top 100 fastest-moving parts to the stock held at our Harworth base."
