I just changed the oil for the first time on a used 2002 Exmark TT HP w/Kawi 17hp engine that I just bought. What a mess. The engine deck has a slotted hole beside the horizontally oriented engine drain plug. I put a large drain pan beneath the slotted hole. Problem is when you pull the plug all of the oil doesn't conveniently go thru the hole, a lot of it spills all over the top of the engine deck. If you own one of these you can picture what I'm talking about, if not this probably doesn't make much sense. Or perhaps most Walk Behinds have this arrangement, I don't know. I'm thinking there's got to be a trick or technique to doing this without making such a mess every time. Can any one tell me how to do this without spilling oil? Also there actually are two drain plugs on this engine. The Kawasaki engine manual that came with the mower doesn't reference both of them. Any one know which is preferred to use and why? I suspect it doesn't matter. Both are at the same elevation so I wouldn't think they both need ot be pulled (plus again the manual doesn't even mention the second one). Thanks for any help.
