Apparatus adapted to be mounted on a vehicle frame for the purpose of increasing traction comprises an L-shaped framework, a first shaft rotatably mounted on the upper portion of the framework, a second shaft rotatably mounted on the framework and disposed below and spaced from the first shaft, spaced third, fourth and fifth shafts rotatably mounted on the framework and extending outwardly from the second shaft, a power source operable to rotate the first shaft, means interconnecting the first and second shafts to impart rotation to the second shaft, multiple wheels fixed in coaxial relationship respectively on the second, third, fourth and fifth shafts, track means mounted on the peripheries of the wheels, brake means associated with the first shaft and operable to fix the framework to the vehicle, and a second brake means operable to fix the framework to the second shaft.
Apparatus for increasing vehicle mobility with the vehicle having a vehicle frame and comprising a framework, a first shaft rotatably mounted on said framework, a second shaft rotatably mounted on said framework and disposed generally parallel to said first shaft, a power source operable to rotate said first shaft, means interconnecting said first and second shafts to impart rotation to said second shaft, at least one wheel fixed to said second shaft and being coaxial therewith, track means mounted on the periphery of said wheel, a first brake means associated with said first shaft and operable to fix said framework to said vehicle frame, and a second brake means associated with said second shaft and being operable to fix said framework to said second shaft.
