NOVELTY - The device has a traction wheel (8) provided with an electric motor (5) on a vertical axle (16) to provide continuously variable forward speed and/or reverse speed. An articulated final drive system is provided between the vertical axle and the traction wheel. A scalable and flexible main chassis (9) is provided with an operator platform suspension system. A global positioning system (GPS) monitors slip of the traction wheel. An inner shaft (17) is slidingly mounted inside a housing (17a). The housing is connected to the chassis through a rotary joint assembly.    USE - Multi-utility hybrid traction device for use as a mobile electric power source to run an electrical appliance (all claimed) for agricultural service and rural transportation.    ADVANTAGE - The device generates tractive force with minimum carried weight, provides variable ground clearance and track width, improves safety of an operator, and increases the operator comfort with better control at relatively higher speed. The device is inexpensive, light in weight and simple to manufacture. The device provides a unique hitch system with or without ballast weights to provide improved stability on slopes enabling haulage of heavier loads, and improves maneuverability by a four-wheel electrical steering system with different modes to optimize tractive efficiency and field capacity for performing regenerative braking effect. The device generates low soil compaction, and has better fuel economy and variable ground clearance for movement over crops. The device utilizes a hitch linkage system below the main chassis to enable draft force to be transferred downwards on supporting wheels, so that the device is easily pulled with better stability on the slopes.
