A feedstock processing apparatus for applying, distributing, and compacting feedstock in defined layer heights may include a chassis with a traction drive and a first and second undercarriage, a frame structure that connects the two undercarriages over a span width of the feedstock processing apparatus, a material feeding device coupled to the frame structure, a material distributing device coupled to the material feeding device and displaceable in certain sections over the span width and configured to apply the feedstock in layers on soil in different, predefinable height positions between the undercarriages, and a compacting device displaceably mounted on the frame structure and/or the material distributing device. The compacting device and the material distributing device can be displaced in a manner dependent on one another respectively along a predefinable movement path. A corresponding method is also disclosed.

A rammer includes: an engine; a reciprocating mechanism (3) including a crank shaft (13) and a connecting rod (14), and configure to convert a rotational force of the engine into a reciprocatory force; a leg part disposed in a forward inclined position in a traveling direction and configure to be moved up and down by the connecting rod (14); and a compacting plate disposed on a bottom end of the leg part. The crank shaft (13) is disposed orthogonally to the traveling direction. The reciprocating mechanism (3) includes a belt reduction mechanism (16) and a gear reduction mechanism (17).

A hand-held power tool has a lower mass and an upper mass. The lower mass has a tool and a working device for causing the tool to effect a work movement. The upper mass is movable relative to the lower mass and has a drive motor for the working device. A first vibration decoupling device is arranged between the lower mass and the upper mass for decoupling the upper mass from the lower mass in terms of vibration. A guide drawbar guides is provided for guiding the work tool by an operator. An electrical energy storage provides electrical energy for starting the drive motor. A drawbar carrier is carried by the upper mass and is connected to the upper mass via a second vibration decoupling device. The guide drawbar is attached to the drawbar carrier, and the energy storage is carried by the drawbar carrier.
