The system is composed of two variable diameter pulleys with a belt in between. One pulley has a hydrolic cylinder attachment that controls its diameter and the diameter of the second cylinder simply 'follows' the first through a spring loaded arrangement. The hydrolic system is under the control of the operator. This system works quite well; at least the ones that I am familiar with did. No maintenance was ever required, etc. But they were huge; size was not a serious factor on the side of a big piece of field equipment. It is hard for me to picture a manufacturer development anything like the above that would fit in as small a space as our standard car transmissions. -- Albert H. Spinks - 71BU072120
