Stake in a machine chamber is hammered by hammer through a pad, to prevent damage to the stake. The hammer's lifting, arrestment and lowering is controlled mechanically. The hammer lifting mechanism is driven by the tractor's hydraulic circuit (lifting + lowering by plunger piston).

The hammer is equipped with longitudinal and transverse tilts, controlled by hydraulic double-acting cylinders, which are connected to the hydraulic circuit of the tractor by quick connectors. Positioning of the machine is by spirit-level. Hammering of the stakes is in the tractor's axis.
