New to this fourm and I know this has been covered before but haven't seen a specific answer. Just bought an old b6200 hydro. With a great bend front loader. The hydros are slow, very slow. And the three point hitch is also slow and pretty much unresponsive if rpms are below 2000-2500. I've read about checking the relief valve but have no idea where to look for it. Can someone here help me out ? I do plan on doing a fluid/filter change eventually but would like to see if the relief valve is the problem. I do not hear a difference in sound when the bucket hits the stop so that makes me thing fluid might be making its way past the valve. Any Info would be great. Also are there any service manuals available for free on line somewhere ?
