Abstract: A snowmobile is described having a frame with left and right sides with left and right suspension assembly disposed thereon. Left and right spindles are connected to the left and right suspension assemblies. A left ski is pivotally attached to the left spindle and a right ski is attached to the right spindle. Rotation of the left and right spindles alters the ski stance of the snowmobile. The stance may also be altered in other ways, which are also disclosed.

Abstract: A suspension for a vehicle includes an upper A-arm and a lower A-arm. A leg with an axis is rotatably connected to both the upper A-arm and the lower A-arm. A mechanical link is rotatably connected to the leg so that movement of the mechanical link applies rotational force to the leg to cause the leg to rotate about the axis.

Abstract: Blades are used in association with snow buckets articulated from snow-removing vehicles. In a preferred embodiment, the snow bucket comprises rotatably mounted about its lateral sides, a floating snow blade outwardly projectable substantially horizontally in front of the lower portion of each of the side walls of the bucket, as to float according to the conformation thereunder and to confine and to force the snow between the snow blades and the bucket to enter the bucket and to shovel it and thereby increasing the snow content of a bucket per stroke. Preferably, the floating snow blades are outwardly projectable substantially horizontally in alternation, in front of or in the back of, the lower portion of each of said side walls.
