Hello Leo, Sorry I did not see your post earlier. I am proud owner of a 5 Deutz tractors, among them is 3 06's: a 68, 100, and 130. I cannot provide any requested diagram, but for all my Deutz tractor needs I contact Landwehr Repair. They have been selling Deutz tractors forever, and continue to sell new and reconditioned ones. Dale knows them inside and out. His advice is free and has all parts you would ever need usually at reasonable price. Website is linked. Hope this helps. The 06's are reliable old workhorses!
