I bought a 2019 MF GC1725M Sub Compact Tractor with 60 inch mower w FEL - Very nice machine- My question is when starting the tractor cold and raising the bucket and mower the hydraulics are quiet. After operating the the mower or FEL or just running the tractor - I start to get a hydraulic squeal after the tractor warms up and when I lower the RPMs, when I raise the FEL or mower the noise will go away but will come back , the noise goes away if the mower/3pt hitch lift leaver is is moved around center I m thinking a shuttle valve is not centering ,but then again I would think the mower or 3pt hitch would raise.The dealer was out once and felt the hoses to the power steering was vibrating , every time he would move them the noise would go away, Has anyone had this issue , Thanks in advanced for any insite - tractor has 12hrs
