Apparatus is described for use in a vehicle having a forward motion transmission operatively connected between an engine and the output shaft connecting the drive wheel and a reverse drive mechanism arranged to be operatively connected to the output shaft for driving the vehicle in reverse. A speed change shift device is arranged to operate the forward motion transmission and the reverse drive mechanism so as to prevent simultaneous operation of the two apparatus.

A vehicle comprising: a driving wheel; an output shaft drivingly connected to said driving wheel; an internal combustion engine operatively connectable to said output shaft through gear train means defining a variable forward motion transmission; a reverse drive motor operatively connectable to said output shaft through a gear train defining a reverse motion transmission; a speed change shift device for selectively connecting either said forward motion transmission or said reverse motion transmission to said output shaft, said speed change shift device including a movable operator containing a plurality of mutually spaced cam means including first cam means operable when said speed change shift device is in a first position to operably connect said forward motion transmission to said output shaft to the exclusion of said reverse motion transmission, and second cam means operable when said operator is in a second position spaced from said first position to operably connect said reverse motion transmission to said output shaft to the exclusion of said forward motion transmission; and means for moving said speed change shift device operator between said positions.
