After long periods of time searching the internet looking for a conversion kit that will suit my tractor I came across a forum in which I asked for any information in relation to the company 4 Wheel Traction whom made the conversion kits for the 100 series tractor. Thinking that I would not get a reply back I acquired a 4wd parts manual which may help in my understandings on how the system works. Below shows the parts manual:
4wt Conversion For Massey Ferguson
Having looked at this parts manual its still unclear on exactly how the box works. My initial idea was to, hopefully manage to get the conversion kit first, then learn the inner workings of the design, but unfortunately this is much easier said than done. There is only some much you can learn from looking at drawings and manuals.
