Abstract
A slotted wall milling cutter for producing a slotted wall in the ground has a drive motor fixed to the cutter frame and a gear means positioned between the drive motor and two cutting wheel gears and which is partly arranged in recesses of a bearing bracket. The cutting wheel gear is constructed as a multistage planetary gear. A particularly high torque is made available on the cutting wheels with this arrangement. In addition, the cutting wheels can be constructed with a very high effective cutting width compared with the total slot width.
