Hey, how is everyone doing out there. Good I hope. Well I got a question about a John Deere LT155. I walked into my barn the other to get it out and cut some grass and there was a large amount of fluid under the rear end. I have called around and everyone is telling me that it is a sealed unit. That may be I am not judging these peoples answers. So if it is leaking there has to be someway to either fill it back up or I have also read about repair kits. I am not sure where the leak is coming from. I got under there and wiped everything down. It may be coming from the gasket. I was just curious if anyone else has had this problem and if so what was the outcome. Replace the rear end or if there is in fact a repair kit. Also if there is a way to fluid back into it what type of fluid goes in there. Thank you for any help that anyone may give. Have a great day.
