Definitions3.1 SnowmobileA self-propelled vehicle intended for off-road travel primarily on snow, having a curb weight ofnot more than 450 kg

8、 (1000 lb), driven by a track or tracks in contact with the snow, steered by a ski or skis incontact with the snow, with the following special classes:3.1.1 CLASS I-COMPETITION SNOWMOBILEA snowmobile intended only for competition as stated and identifiedpublicly by the manufacturer.3.1.2 CLASS II-CH

9、ILDRENS SNOWMOBILEA snowmobile intended only for use by children, as stated and identifiedpublicly by the manufacturer. For a more detailed definition, see SAE J1038.3.2 Operation WeightThe total weight of a snowmobile including a full load of fuel, oil, coolant, tool kit (suppliedby manufacturer),

10、and an 80 kg (175 lb) operator.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-SAE J33 Reaffirmed DEC2000-2-3.3 Curb WeightThe total weight of a snowmobile including a full load of fuel, oil, coolant,

11、and tool kit (suppliedby manufacturer), but without any occupants or cargo.3.4 Unladen WeightThe weight of a snowmobile without load, fuel, and oil, but comprising of all other materialsnecessary for its operation.3.5 Flotation Area (Bearing Area)The projection in a horizontal plane of the area on t

12、he surface of the trackand skis which contact the snow. To account for machine penetration into snow, the projection plane islocated 75 mm (3 in) above a nonyielding horizontal surface supporting the snowmobile while in a curb weightcondition.

Snowmobile Dimensional DefinitionsThe dimensions listed are defined by Figure 1 and are to be takenwith the snowmobile in an unladen weight condition on any unyielding horizontal surface, with the followingexceptions:4.1 Overall LengthThe horizontal distanc

14、e from the foremost part of the snowmobile, to include the bumper andski or ski handles, to the rearmost part of the snowmobile, to include the bumper or other fixed attachments.4.2 Overall HeightThe vertical distance from any unyielding horizontal surface on which the snowmobile, in anunladen weigh

15、t condition, rests to the topmost fixed part of the unladen snowmobile, including the windshield.4.3 Overall WidthThe horizontal dimension of the minimum aperture through which the snowmobile can pass.4.4 Driver PositionThe seated, forward-facing position which is necessary to operate the controls u
