A power and cooling assembly is disclosed for use with a vehicle having a deck for a rotatable tool such as a mowing blade. An electric motor is mounted on the deck and used to drive the blades by an output shaft. A circulating pump is connected to a housing of the electric motor and is also driven by the electric motor. The circulating pump is hydraulically connected to at least one sump on the vehicle and at least one electrical component of the vehicle to provide cooling thereto. Additional cooling pumps may be provided on the vehicle and may provide cooling to additional electrical components.
