Help Cub Cadet

I have a cub cadet LT1050 purchased 2005 with 500 hours. It has a Koehler 26 HP engine. It has started leaking oil from somewhere up under the engine cylinder just up front of the oil filter. Anyone know what this involves or where it could be coming from. Possibly where the engine bolts together??? How major?
 
Is this a twin cylinder Kohler Courage? They give much better service than the single cylinders from that era do. If its a single cylinder, then its pretty much done.

You may just have to take the cover off and see what you find. Of course that involves removing the engine from the mower. I am thinking Kohler used a special RTV type material to seal the oil sump on that engine. If you take the sump off, its a good idea to replace the pto crankshaft seal.
 
Check the drain valve. Had one in the shop this spring and the drain valve was leaking on it. Kohler engine on it also. Not much room to work there but, I removed the cheap valve and replaced it with a pipe nipple and cap. No more leakage!
 
If it is a Courage engine.

Check the low oil sensor that is screwed into the front top of the filter housing. The O Ring on them can deteriorate and the unit itself can go bad and cause oil leaking.

Best photo I could find in a pinch. Just to show you the sensor's location by the oil filter.

Much thanks for replies. This engine is the Koehler Command 26 twin cylinder. To this point it never used oil. Just started leaking pretty bad quite suddenly. The writing on top of the engine shows it has low oil protection. Can anyone point me to where the low oil sensor is on this engine. I removed the covering and could not see anything. It only starts to leak after running for a few minutes. Thanks.
