Abstract
Abstract A motor driven toy mobile playset has three articulated deck sections. Each section has a wheel and axle assembly powered by a battery motor driving a single drive shaft that extends through all of the sections transverse to the wheel axles. When supported upon a level playing surface the sections form a chassis having a generally planar deck. Various bores and slots are defined on the sections for removably mounting accessories. Some of the accessories are mountable within bores in the ends of the wheel axles. One accessory is driven by a power take-off. A crane boom is mountable in a number of positions including one which provides a manually operable winch with a hook and cable. The front section has a lighted bridge structure with a spotlight and an upper head lamp bar both utilizing a single light bulb connected to the battery.
