Abstract:
1. A soil stabilizer apparatus, comprising: a chassis having a direction of travel from a rearward end toward a forward end; a pair of forward ground engaging supports and a pair of rearward ground engaging supports supporting the chassis from a ground surface, all four of the ground engaging supports being driven and steerable; four lifting columns supporting the chassis from the four ground engaging supports, so that a height of the chassis above the ground surface may be adjusted; first and second pivot arms having upper and lower ends, the upper ends of the pivot arms connected to the chassis and defining a pivotal axis transverse to the direction of travel; a working drum mounted on the lower ends of the pivot arms and including a drum axis extending transversely to the direction of travel; a combustion engine transversely arranged between the pivot arms and behind the forward running gear, the engine having an output axis co-axial with the pivotal axis so that the pivot arms and the working drum pivot about the output axis; an operator's platform located on the chassis, the operator's platform being transversely movable relative to the chassis; at least one mechanical power transmission device received by at least one of the pivot arms to transfer drive power from the engine to the working drum, the power transmission device including a belt drive including a first pulley driven by the engine, a second pulley for driving the working drum, a tensioning pulley, and at least one drive belt connecting the pulleys; and a clutch operably connected between the engine and the power transmission device.
