Since the engine is an inline 4 when one piston is moving up another is moving down so the crankcase volume doesn't change. So crankcase ventilation is only needed for blow by.

There is a narrow tube that runs from the front of the engine to the air cleaner. It's tucked to the rear of the air cleaner so you're not likely to notice it with the hood on the tractor. Presumably its purpose is to provide some positive crankcase ventilation. Supposedly they often get clogged so you might pull it off and make sure it's open.

If you're blowing a lot of smoke out the dipstick though you've probably got a ring problem. They might just be stuck from sitting and might clear up from operating it some.

I started to pull the pans and then decided to wait until I have fluid to go back in them
