it says Kohler:ExtremeFunny::ExtremeFunny:

on a serious note depending on how much of a furrow you had it may have just gotten to much oil in one of the cylinder and coughed it out the breather. I hope its not what happened to me I had one do that to me when the oil gear broke it puked oil every were when the gear broke but I hope thats not it. my best guess for now

What condition were the breather and air cleaner in when you started?

lets hope not, the oil was just below the full mark when I started to use the plow. saw some drips this morning and checked the dip stick its a little below half now. and it was smoking under a load, but thought it was just burning to rich of gas.
oil burns white gas blackish right?

no clue. I did let it run for a few and then at high rpm held my hand above the carb. I got a fine mist of oil on my hand.

Looks like you've got some pretty serious blowby. A leakdown test would help you assess the condition of that engine.

You should check your valve breather assbly,the orig breather had a rubber valve that got hard or would break from heat and age letting oil blow into air cleaner. I've replaced many and never had trouble with oil in air cleaner after.

OK thanks guys. I'll do some :Detective1: work on it today.

I took it to the fix it shop this morning. I put a qt. of oil in it to put it back up to the full mark. so it pucked out 3/4 of a qt. in less then 3 hrs.
compression checked out ok, (just OK) so I have the breather assbly ordered for it. he has the rings in stock so I'll do the rings maybe in the fall . and do oil seals too.

I got the breather assbly put in. the jacka$$ PO had it apart at some point. it didnt have any gaskets on it and the spacer has gone. the left side was the same, no gasket.

I made the 3 gaskets (one for the left side) and made the spacer for between the breather assbly and the cover.

I tilled yesterday for a few hours and checked the air cleaner this morning. its all dry. and the top of the m18 is oil free.
but still have a good size oil leak. I still used about a 1/2 qt. of oil tilling and it setting over night. there is a 10" round oil puddle under it this morning.
it puffs smoke when it starts and when it accelerates to full power.

is it time for valves, rings and gaskets/seals ? you can see in the video I posted in my other thread it smoked when I accelerated to start tilling. but didnt smoke under the load when tilling.

An oil leak that large is probably a crank seal...I'd check/replace those before getting too carried away.
