The machine is a hand-guided, reversible soil compactor.
The machine is composed of a bottom and a top section.
The bottom section houses the exciter, while the top section
contains the engine and the required controls.
An air-cooled Honda gasoline engine makes the exciter vibrate
via a centrifugal clutch. The generated force is transmitted
between top and bottom section via a V-belt.
The engine speed is adjusted between idle speed and full-
throttle speed via a gas lever.
Forward and reverse travel is variably controlled with a handle
via a hydraulic system.
