摘要
A tricycle type vehicle with two forwardly disposed spaced apart drive wheels and a rear centrally disposed caster wheel. Spaced apart auxiliary drive wheels flank both sides of the rear caster wheel and are arranged for vertical movement on the vehicle. The auxiliary drive wheels may be in an up inoperative position to permit the vehicle to act solely as a tricycle with two driving wheels, or down in ground engaging operative position causing the caster wheel to be raised off the ground and thus converting the vehicle to a four wheel drive vehicle.
