Krupp’s Grosstraktor III as monument
at the barracks of Panzer Regiment 5 in Wunsdorf, 1937.
None of those prototypes entered production due to numerous problems and defects encountered during tests. In 1933, after completed test and completed co-operation with the Soviet Union, four functional vehicles returned to Germany. Krupp and Rheinmetall-Borsig prototypes were used for training purposes in continuation with work started at Kama. Eventually, they were handed over to the 1st Panzer Division and took part in maneuvers in August of 1935. Both Daimler-Benz Grosstraktors ended up as monuments at 1st Panzer Regiment headquarters at Erfurt and 5th Panzer Regiment headquarters at Wundsdorf. After 1935, remaining four prototypes were used for training purposes at Panzer Gunnery School at Putlos. In 1937, one of Krupp and Rheinmetall Grosstraktors ended up as a monument at 5th Panzer Regiment headquarters at Wunsdorf. The remaining two were either scrapped or used for target practice.Grosstraktors were extensively tested and lessons learned from them provided the German designers with valuable experience, which was then used in the direct development of Neubaufahrzeug and eventually of other designs.
