Steyr tractor, single differential, needs a battery and a front tire puncture. It has a plow. The lift is not working. It needs air bleeding. The tractor is for inheritance, valued at 15,000 from Sudanese workers, but we haven't sold it. Its engine is original. I changed the differential before my father's death for 11,000. I took it off one tractor and installed it, and no gear was damaged. I brought a tractor mechanic, and he worked on it, and it started working. I added a video of it running. However, he told me it needs injectors and filter cleaning because it cuts off the diesel. It runs and continues, then cuts off and stops.
