   This is what the bottom tranny area looks like on my old Snapper   
   Snowblower. The silver colored disk is belt coupled to the 5hp engines   
   power-takeoff shaft. It spins all the time the engine is running. The   
   rubber disk contacts it when a hand grip is squeezed. The lever in   
   front slides it left to right changing speed and reverse by contacting   
   the other side of the disk. Everything you want is already here. This   
   is a common drive mechanism in the snowblowers here and some   
   lawnmowers...
