Abstract
A swing arm for a snowmobile has an upwardly curved, stepped, or angled intermediate portion that increases the swing arm's ground clearance relative to conventional, straight swing arms. The increased ground clearance permits more snow and other elements to pass underneath the swing without contacting the swing arm.
