I just bought a low hour 6210 2wd cab tractor. When driving straight cutting hay you have to constantly turn steering wheel CCW. The steering wheel will make a complete 360 degrees turn in about 30 seconds. I am pretty sure this is not right is it? I was told it was either the steering motor or the hydraulic cylinders leaking internaly. It has 2 steering cylinders that controls front steering. How do i tell for sure which one of the three is leaking inside? Is the steering hand pump hard to remove on the 6210?
