An adjustment mechanism for a vibratory mechanism of a surface compaction machine, the adjustment mechanism includes a torque limiter coupled between the first eccentric shaft and the second eccentric shaft that prevents relative rotation between the shafts and a phase adjustment between the shafts when a net torque applied to the torque limiter is less than a locking torque threshold. Application of a net torque to the torque limiter that is greater than or equal to the locking torque threshold causes the first eccentric shaft to rotate with respect to the second eccentric shaft. An actuator subassembly selectively applies a linear force cause a first torque to be applied the first eccentric shaft sufficient to apply a net torque to the torque limiter that is greater than or equal to the locking torque threshold to cause the first eccentric shaft to rotate with respect to the second eccentric shaft.

A control apparatus for a soil compacting apparatus such as a vibratory plate has a movable operating element for specifying a running direction of the soil compacting apparatus by way of an operator, and having a hydraulic master device, with a master cylinder, in which a master piston can be moved to and fro in a linear manner, in order to generate a hydraulic signal. A hydraulic connector serves for coupling hydraulic components of the soil compacting apparatus and for transmitting the hydraulic signal from the master device. A transmission device is provided for converting the movement of the operating element into a linear movement of the master piston, it being possible for the operating element to be moved between a first position (V) and a second position (R). The first position corresponds to a maximum forward movement of the soil compacting apparatus, and the second position corresponds to a maximum reverse movement of the soil compacting apparatus. A latching device is provided for releasably holding the operating element in a predefined position, for example the first position.
