The Case-o-matic from case was a totally different system from the rest as there was no actual speed change. You had basically the same system as a modern auto trany in a car today with a torque converter but with a manual lock up and no shifting. When you are in direct the converter is locked allowing no slippage. In torque mode the converter was allowed to slip which perfectly matched engine power to load, the harder it pulled the slower you went til wheel slippage occured. As the load ligtened you gained speed til you got close enough and could lock up the converter again. This system worked especially well with heavy pto loads like running a chopper because as the pto load pulled down the engine the wheel speed slowed at a higher proportion so that the engine could stay in the power band with almost infinately variable and automatically adjusted speeds in your chosen gear.
