BX1860 kubota Leaking transmission

[marshtg]

I have a BX1860 Kubota that drips some oil from transmission after using front bucket or raising rear blade a lot, seems to be coming from top left looking in from rear. This started after heavy use one day moving heavy dirt. Is there a rubber hose somewhere of trans. Also what is best way to remove rear fender and seat assembly, looks like a lot of work, Thanks for any info.
