Abstract: A track for in-line tires on a skid steer vehicle, the track includes a continuous loop of links with sidebars and a pin and a barrel, the pin and barrel together forming a hinge between the links and extending between the sidebars. Tire side guides extend upward from the side bars to guide the tires along a pathway over the upward side of the hinges. The opposite side of the hinges engage the ground. The tire side guides can be permanently attached or temporarily fastened to the sidebars at selected positions and moved to other selected positions to convert the track for use with different sized tires, thereby proving a convertible track and a method of converting a track. A system for forming and closing the track as a loop of links is also disclosed.
