Abstract:
1. A drive assembly comprising: a rotatable drive shaft; a ground-engageable wheel mounted on the drive shaft and rotationally decoupled from the drive shaft with the drive shaft extending through the wheel; a drive transmitting member rotationally coupled to the drive shaft; a clutch member rotationally coupled to the drive transmitting member and movable relative to the drive transmitting member, wherein the drive shaft extends through the clutch member; a wheel drive member rotationally coupled to the wheel and adapted to receive rotational energy from the clutch member, the wheel drive member mounted on the drive shaft and rotationally decoupled from the drive shaft with the drive shaft extending through the wheel drive member; a drive receiving member mounted on the drive shaft and rotationally decoupled from the drive shaft with the drive shaft extending through the drive receiving member, wherein the drive receiving member is adapted to be engaged with the clutch member and with the wheel drive member to transfer rotational energy from the drive shaft to the wheel and wherein the drive receiving member is adapted to be disengaged from the clutch member to substantially prevent transfer of rotational energy from the drive shaft to the wheel; means for biasing the clutch member toward a position in which the clutch member transfers rotational energy to the wheel drive member; and means for moving the clutch member axially relative to the drive shaft, wherein the means for moving the clutch member is a lever.
