I haven't fully decided on how I will synch the front drive with the rear. I think to start with I will mount an electric clutch on the hydraulic motor so I can completely disengage it from driving the front differential when not needed. I know Case 220 and 446 tractors have hydraulic motors that are control with a valve mounted under the dash. If I can use something like that I may be able to connect it to the lever control on the cub rears. I think it would be a trial and error situation to sync them as close as possible. Additionally I consider the front an "assist" rather than full time. I think if I have a momentary switch hooked to the electric clutch I could just engage the front when needed. Lots to figure out there yet. My plan is to get the grader functional with the rear drive first befor I tackle the addition of the front drive.
