A riding lawnmower vehicle includes two main drive wheels, at least one caster wheel, an electric traction motor, an internal combustion engine, a generator driven by the internal combustion engine, and a lawnmower. The electric energy generated by the generator can be supplied directly or via an electric accumulator to the electric traction motor. The main drive wheels are independently driven by the electric traction motor, which can operate as a traction power source. When viewed from one end to the other end in the width direction of the vehicle, the internal combustion engine and a secondary battery operable as the electric accumulator overlap each other, and the main drive wheels overlap at least a part of at least one of the internal combustion engine, the generator, the secondary battery, a fuel cell, a capacitor, an inverter, a cooling device, a mower driving motor, and a grass-collecting duct.

A loudspeaker has a cooling system in which a pole portion has a shorting ring made of non-magnetic conductive material that stabilizes magnetic field to reduce distortion of sound and a heat dissipation plate that couples to the shorting ring to facilitate efficient dissipation of heat. The heat generated by a voice coil of the loudspeaker is transmitted to the shorting ring and is conducted to the heat dissipation plate which acts as a heat sink to allow the heat dissipation. A multiplicity of shorting rings may be provided to further reduce impedance modulation, each of which is coupled to the heat plate. The heat dissipation plate has a gap in an axial direction of the loudspeaker to prevent an electric current in the shorting ring from flowing through the heat dissipation plate.

A hydraulically powered fan system for the cooling system of a vehicle. Two hydraulic motors, powered by a hydraulic pump, drive a common fan which cools a radiator. When hydraulic flow in excess of that required to power a single motor is present, a second motor is placed in parallel with the single motor, thereby reducing system pressure, and reducing the power consumed by the pump.

A cooling system includes a radial fan rotatable by an axis to deliver radial air flow to the cooling system, a plurality of heat exchangers spaced radially from the fan and arranged around the fan in a box-like configuration to receive the radial air flow therefrom, with the heat exchangers bounding an interior space of the cooling system. One of the heat exchangers is provided in the form of a charge air cooler that includes a first flow path for a charge air flow in heat exchange relation with a second flow path for an engine coolant flow of the vehicle. The cooling system further includes a surface associated with the charge air cooler to substantially block the radial air flow from exiting the interior space through the charge air cooler.
