From 1925 the model M III was offered also with diesel engine, the mod. M II, was the first diesel-excavator offered with backhoe and skimmer ( from 1931).

The models MB, MC, MD, ME, MF were offered from 1926 and were special shovels for quarries. They were developed from the models M III bis M VII. The “JRA” was built on request of an South African goldmine and the “ KRA”, the largest shovel on caterpillars, for the Dyckerhoff Cementfactory in Amöneburg (near Frankfurt) ( see below!!).
