In the early 1960s, the brand cooperated with ČZ Strakonice on developing the Type 998 (known as Agromobil) and, a few years later, the Type 990. Only a few prototypes were produced – their exact number is not known, but it was probably 13 – of which at least two have been preserved. One is owned by the ŠKODA Museum, the other by the Military Museum in Lešany (together with a Type 973, known as Babeta), both these vehicles appeared in the 1964 film If a Thousand Clarinets (Kdyby tisíc klarinetů).
As part of its ŠKODA 1203 modernization project, the brand had considered producing a 4×4 version for farmers (Type 779, 1970).
