Kohler Courage 20---what beside main crank seal will quickly dump all oil from under engine?

Something you did when you changed the oil if it was ok before.
for example oil filter not correct.
sump drain plug overtightened and cracked the block.
Spraying oil under pressure is a indicator of the oil filter area.

A $15 dye kit from the auto store would have saved you lots of time.

Makes a lot of sense to us!

Wet cold weather and health issues have kept me indoors and away from the mower for a week now. I did pick up a dye kit and hope to get the motor upright so I can try it this weekend.
I really did like the suggestion to replace the son-in law.

Purchased a Toro Bronco new 15 years (or more) ago and it has had a very babied life at a lakehouse that only gets used about 3 times a year. I had a need to loan it to son-in-law that burned up ( it literally caught on fire ) his new JD Zero turn.

Never had any issues at all with the Toro / Kohler other than replacing a couple of tires that dry-rotted.

I Picked it up and made a trailer ride back to home. Did a full tune-up and oil change. When I cranked it all the oil immediately sprayed out from beneath the motor in just a couple of seconds. I felt pretty sure it was a main seal on the crank because of he volume and speed with which it occurred and just ordered a new OEM seal. With the mower lifted overhead and pulleys removed The part of the motor around the crank is dry and dusty.
After a lot of digging online I stripped the top end of the motor and it does not even suffer the common oil leaks and all side of the engine are still dry and dusty.
When the oil was being discharged it came out like it was under high pressure directly down on the trailer ..

That was a lot of background for a relatively simple question. Does the Kohler Courage 20 have any type of opening beside the main seal on the very bottom of the engine that could of dumped all the oil in just a few seconds. If not, I am suspecting a catastrophic block crack. I can pull the engine and inspect the bottom but that simple act will cost me considerably and I will probably just cut my losses and try to find a used mower.

Are you sure the new oil filter had the gasket properly in place or that the gasket from the old oil filter came off and it didn't double up?

THIS!
Please check the oil filter.
You may have a 2 gasket situation!

So you just changed the oil and all of the sudden you have an oil leak. And you reinspected the oil filter that you just put on? The seal from the old filter may be stuck to the engine or you may have rolled the new seal from not putting oil on it before installing. Your engine is proly fine. Also if it has an oil cooler with rubber hoses check them. My $5 is on the oil filter.

I have been a woodcarver for roughly 50 years and have always been really active. Congestive heart failure for over 10 years but it did not really affect me much. Now I have a rarer version of an already rare disease called Grover's. The skin starts to delaminate causing disconnected layers in small " tears" most often found under sweat glands. Normally you get what looks like chigger bites that itch terribly 24/7 and last a month or more. In my version the adjacent tissues tears as the sweat glands start to accumulate sweat but cannot open up to release the sweat. that tears some nerve endings resulting what feels like very bad prickly heat quickly turning into what feels like bee stings. It is triggered by warm air, direct sunlight, physical exertion, emotional stress, spicy food. Lost about 40lbs of muscle mass in 6 months.

Wow, that's rough...sorry to hear. Hopefully you can find a specialist who can treat it and get you some relief.

The main seal is not that difficult to replace and is not a large expense. That's if the engine pully comes right off. No need to pull the engine off. The oil will ride down the crank and settle on the pulley. Mine would be intermittent. Couple of sheet metal screws into the seal and it pulls right out. Lube the new one well and gently slide on. I used a short piece of 1.5" pvc pipe to tap into place.

Like Ran said, oil filter the oil filler tube's O ring and the valve cover gaskets are everyday leaks.

Not to be harsh on the OP. The only thing he did was an oil &filter change so that’s where he needs to look should not have pulled the engine!
Hope he is feeling better!
