Abstract
An apparatus providing auxiliary traction to a riding lawnmower or similarly light off-road vehicle having a drive wheel with a hub anchored to a drive axle. The apparatus generally includes at least one traction bar having a pair of traction ends equally spaced beyond the outer circumference of the wheel. The traction bar anchored to a carrier mounted to the hub of the drive wheel. A traction bar of variable length may be achieved by having two traction arms, one telescopically received within the other, with a length-locking means such as retainer pins inserted through aligned bores extending through the overlapping traction arms and the carrier mounted to the hub.
