doing maintenance on my 36" metro w/ 15 hp kohler engine, the machine is great, thanks for improving my business so much now to the problem, trying to change the oil and oil filter, well, on the crank side, where the oil filter is, the so called "oil drain plug" is in a terrible spot, not very near the edge of the machine, very small bolt and theres wires hanging in front of it, the bolt is impossible to get off as well. now, on the other side of the machine there is a plug ( it looks like an oil drain ) and right under it is a hole to the ground, that looks like it is the right thing to mess with, but the engine manual only talks about the tiny oil drain plug on the crank side. If i can get the bolt off i will have to get a funnel, and shove it under the plug, and then get an oil pan that the funnel is leading into, am i doing something wrong? please help thanks, clint P.S., when im changing the oil filter it sais put it upside down in a pan and fil the thing up to the threads ( if im correct here, the threads are at the VERY bottoms ). now, if the bottom is up in the pan, and it is down on the machine, how are you going to turn it over, put it on the machine, and tighten without spilling any oil?
