<p>WHEELED SLED A wheeled sled is provided with crossed steering bars pivoted to each of the rear axle brace, front axle brace and steering handle. The steering bars pivot the axle braces in opposite directions as the steering handle is moved to minimize the turning circle. Longitudinally extending coil springs bias the steering handle to a neutral position. Handle grip brakes are provided on the steering handle for braking the front wheels.</p> |
