Overview
The BAUER eCSM is a prototype for electrified Cutter Soil Mixing (CSM), introduced at Bauma 2025. Twin electric motors drive the CSM cutter head in place of the conventional hydraulic drive, aiming at lower emissions and simpler power management for soil-mixing walls. This record is a technology / prototype entry — not a series product. Availability, series specifications, torque, cutting envelope, power ratings and pricing are not confirmed and must not be presented as production values.
