Abstract
A power driven snow bob is provided with a detachable fuel tank which can be readily attached and reattached in a rapid and expedient manner in a cold outdoor environment. To assist in retaining the fuel tank, it is formed with a groove on its under surface which mates with a cross bar portion of the frame and with a sliding interlock portion at one end for sliding in an interlocking relationship with a retaining means on the frame. At the other end of the fuel tank, a quick connect and disconnect means comprising a push-pull retaining pin is inserted through aligned apertures in a fuel tank and a grommet on the fuel tank. The fuel line is detachably connected to a fitting having a shut-off valve.
