Ouch...
Rule on the farm is never leave machinery parked under a (large)tree.
LOL< I've told this before... the tractor I mentioned above being totalled..
Shredding one spring, and a storm was coming in, late cold front. Parked under a fairly large, appx 48 inch diameter trunked water oak. Looked up. Thought about the weather. And then drove out from under it and parked in the open pasture.
Next morning the wind had torn the top of the tree out and a fairly large limb, around 30 inch diameter in all its glory and flown far enough to land on the tractor. If I'd have left it under the tree.... it would have had a few scratches....
As it was it was not dead, just took some fixing and some fenders could not get quite right, and finding old parts is tough...
It still shreds today, and will shortly when the damn temp drops to under 100 for the evening
