I have a 10″ two furrow plough with some linkage parts missing. I have the top link and RH adjusterble bottom link apparently complete. On the LH side I have the lower link arm and a green bracket and turning handle. I do not know what else I need. The handle turns a threaded bar. What fits on the thread? There is also a hole in this bracket. I believe a bracket goes from this fitting across to the RH frame which does have a bracket fitted. Will someone please send up photographs and dimension to enable me to finally fit the plough to the tractor. Thanks
