The tractor is an M4700 '98 model. All of a sudden the remote auxiliary cylinder control valve started leaking hydraulic fluid out of the bottom of the valve through a small hole in the bottom cover plate. From what I can tell from the parts book, it is a new style valve. Is there a rebuild kit available for this valve, or do I have to buy a new $$$$ valve? (I hope not), or can a hydraulic repair shop rebuild it for me (none real close around me). I hope you experienced Kubota hydraulic experts out there who can/will give me some guidance on this problem. Thanks in advance!
