Device for driving a tool (4) positioned on a pivotable part (2), said device comprising a combustion engine (5) or the like which is arranged stationary, such that the extension of the motor drive shaft (6) crosses the pivot axis (22) of the pivotable part (2) and is square thereto, with the motor drive shaft driving a transmission shaft (26) by means of a bevel gear transmission (15, 16, 17), said transmission shaft being supported by the pivotable part (2) in such a way that the extension of the axis (36) of the transmission shaft also crosses the pivot axis (22) of the pivotable part and is square thereto. The wheel (16) being located between the wheel (15) which is directly driven by the motor drive shaft (6) and the wheel on the transmission shaft (26) has been mounted on a wheel shaft (18), the axis (21) of which coincides with the pivot axis (22) of the pivotable part (2). <IMAGE> |
