Abstract
A soil treatment apparatus has a plurality of tool units that have at least one bracket, at least one plunger tool and at least one stop for the plunger tool. The bracket with an end section on a chassis is driven up and down to pivot about a first pivoting axis. The plunger tool device is linked at another end section of the bracket to pivot about a second pivoting axis. The stop is formed such that plunging is carried out at a predefined plunging angle. To enable faster operating speeds, the first pivoting axis is provided behind the second pivoting axis as seen in a driving direction, and the plunger tool device is linked such that whenever the bracket is pivoted about the first pivoting axis it is subjected to a centrifugal force in a direction toward a position limited by the stop.
