I have. 2000 873 G with 3100 hrs. I have kept the machine maintained and keep it pretty clean. I have noticed a little oil leak but it has not been bad. This evening I loaded it heading home and noticed when I got home that there was a decent amount on the trailer floor. It seem to be running out from under the engine and out the back. I pulled the side panels and looked in but could not see any signs. Since I keep it pretty clean I though I would see the leak. What are some of the things I should check? It runs like a champ so I wouldn't think it would be a major issue. I'm thinking it's a fitting or gasket. What thoughts do you guys have?
