Farmtrac 545 leaking oil from cotter pin

[Dcg1026]

My 545 is leaking from the hole with the cotter pin on bottom of gear housing. It’s always had a drop or two but I ran it the the other day for a few minutes for the first time in a while and now there is a fairly large pool of oil underneath and it’s still dripping. Somebody give me some good news……
