Is this true?

[Doofy]

Owners manual states that the exhaust outlet should be covered when the tractor is parked outside. This is to prevent the wind from turning the Turbo and ruining the bearings due to lack of lubrication.

Is this really a problem? Does anyone actually do this? Puzzled!

For that to happen, the wind would have to wind its way down the exhaust, thru an open exhaust valve, into the cylinder, thru an open intake valve on the very same cylinder, across the turbo and thru the air filter to freedom.

Seems like an unlikely path.

It's most likely to prevent moisture from condensing (ambient humidity) inside a cylinder etc. through path describe in above response...

FWIW since I was a boy every time we left a tractor out and rain was forecast we put a bucket over the exhaust. I find myself doing that now out of habit. IIRC it had nothing to do with turbo but more with several inch's of rain fill the muffler

Yes it's true (or possible). You'll hear it discussed more when talking about towing something with a turbo though. I know I've seen ads for exhaust covers, for this exact purpose.

I put a can on the exhaust for awhile until I bought an exhausts flapper at Tractor Supply, so I didn't have do to anything, and couldn't forget to put a can on it.

they rattle to much for me . drives me crazy

The exhaust pipe is horizontal and down low at the frame level. The exhaust tip is cut at a 90 degree angle pointing to the side and not down. Perhaps this would catch and funnel the wind easier. Maybe just a tin lid with a magnet would suffice.

I can understand that, and they definitely do rattle. It's just something that never bothered me. A rattle, squeak, squeal, etc. that I can't identify will really bother me until I find it and fix it. But if I know what it is, and know it isn't going to hurt anything, then it just doesn't bother me.

I fit "flappers" to the exhaust stacks that open to the sky. I enjoy the way they pop and clap at idle.

On a less humorous note, I once tried parking the Bolens under a small shed roof. Well, The upturned and wide open exhaust stack just happened to align with the drip line of the shed roof.
Not only the muffler filled with rainwater, but the cylinders and crankcase to boot.

I was a bit slow to catch on when the engine sort of baulked when I tried to start it up. The engine did start without too much trouble. But then the oil fill/dip stick assembly blew out of the crank case in a few minutes time.
Emulsified oil blew all over. ;-((

Refitted the tube, changed the oil, ran the dickens out of the engine for a few hours and called everything good.
Come winter season with snow blowing needs, a head gasket blew. I think the two events were related! ;-)

That tractor is fitted with an exhaust outlet that faces the horizon now ;-)
