Was using my 4000 to mow hay last weekend and when I went to pick the haybine up at the end
of the field, I had no hydraulics. I still had good steering and good brakes. I took the
tractor to my shop. Pulled the transmission screen it was clean. Replaced the hydraulic
filter still no change. Checked the pressure adjustment spring in the main hydraulic pump
and no issues there. I put a pressure gauge on the rear remote. I was told it should read
anywhere from 2100-2250. I got 1500psi. When i revved the tractors the pressure would
bounce between 1400-1600psi. Does this sound like the main hydraulic pump is bad or could
it be something different?
