EurOpal - Perfect technology for improved work quality:
The two to seven furrow EurOpal mounted ploughs are characterised by high strength at low weight. They are easy to pull and consequently very efficient to use.
VariOpal - For wide and narrow ploughing, wide furrows for wide wheels:
The VariOpal perfectly fulfils all requirements for ploughing. Good ploughing performance relies heavily on the working width and working depth of the different bodies.
