In 1939, preparatory work began on the design of a new earth-moving machine - the KG-65 ( literal translation from the Russian language ) rotary digger. But the work was interrupted by World War II
The KG-65 was inducted into the armed forces of the Soviet Union in 1948. Serial production took place at the Dimitrovsky plant. For the development of the machine, the author's collective was awarded the Stalin Prize.
On KG-65 was used rotary working with gravity soil unloading. The machine had a serious drawback - it was designed only to create straight trenches. Ditches used as fortifications, almost always had to have a rounded shape.
Later, the experience of using the KG-65 in the army led to the modernization of the machine, which was given the designation ETR-152. The archaic chain drive from the landing gear mechanics was replaced by a hydraulic drive.
The KG-65 very quickly ceased military service due to the low transport speed and low productivity caused by the gravity unloading of soil from the excavator segments.
