The Snow Blower is an obstacle that is in Winter Wipeout. It was a different version of the Pitchfork Tumblers. However an extra prong was added to the objects and the second set spins counter clockwise.
Because this was a summer episode they were renamed the Lawnmowers, the colors were sliver on the prongs, red on the shape, and the trampoline was green. It was exactly the same but the trampoline height between objects was slightly taller.
