HI and welcome to JA. THE first question is does this tractor have power steering?
Hi and sorry the question closed and only you could reopen it the first thing to do is add 1-2 gallons of extra hydraulic oil and if the problem goes away then you are having a suction problem on the implement pump. Give this a try and get back to me and if it don't work then you are probably looking at a worn pump that is causing the problem
IF you need any more help just ask
IF you agree with my answer then please accept,feedback is also welcomed THANKS
