Hey fellas I was looking for a bit of help here, with my 784 MFWD, its got an IH loader on it also. my hydraulics seem sluggish at an Idle and even 1000 rpm when I am maneuvering around the yard steering takes a lot of effort. we did a steering pressure test and it was 1600psi for the steering pressure relief valve which the service manual says is proper, also had pto problems when I put my snow blower on the tractor this winter, I can stall out the pto. I put a flow meter on the tractor and did a flow test at high idle I have 15gpm a little less once oil is up to temperature, but at idle theres only about 5-7gpm (not sure what it should be because manual doesn't say) tested the IPTO pressures and they were a bit low so we shimmed up the valve to get it into spec. The main hydraulic relief valve is set and working about 2450psi (book says 2500 psi) I'm fairly competent with hydraulics but was just checking to see if anyone has had any issues like this before, It may be that my pump is getting week but flow doesn't fall off like they usually do on a week pump. Thank you in advance for your help

It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
