I have a 574 ih that I am working on for 3pt lift issue. The man it belongs to states that when he has his rotary mower hooked up the 3pt will just drop sometimes. I have-not actually seen it do this and I mentioned to him about the draft lever but he assures me that he hasn't touched it when letting mower up or down. He thinks it is a pump problem, but pump doesn't seem to be under a load and steering works fine. I have a light weight implement attached now that weighs roughly 300# and it will hold it up all day long with no problems. I was wondering if there was any way to check pressure on pump and what it should be just to eliminate the pump from being the problem.
