In one embodiment, a stand-on mower, comprising a chassis having drive wheels operably coupled to the chassis, a platform arranged between the drive wheels, a front wheel frame, coupled to the chassis, and having pivot mounts and front wheels coupled to the pivot mounts, and a load deck mounted to the front wheel frame and having openings through which the pivot mounts extend.

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.

An outdoor power equipment having sitting configuration and standing configuration is presented herein. The outdoor power equipment can be transformed from the sitting configuration to the standing configuration and vice versa, allowing an operator to use the outdoor power equipment in either a sitting position or standing position. The sitting position can place the operator at least in part forward of a drive axis of the outdoor power equipment, whereas the standing position can place the operator at least in part coincident with or behind the drive axis. The outdoor power equipment can be electric powered in some aspects, with modular and replaceable battery packs.

A housing holding parts includes a plurality of outer circumferential plates connected with each other to form a first enclosed space, one or more of the outer circumferential plates having a total of two or more outer holes formed therein, and a gutter member connected to at least two outer circumferential plates, the gutter member having an inner hole formed therein, wherein a second enclosed space is formed by the outer circumferential plates and the gutter member, the outer holes communicate with the second enclosed space, and the inner hole is provided to be offset from each of the lines passing through each of the outer holes which are perpendicular to the outer circumferential plates in which the outer holes 8 are formed.
