My dumbass never thought of that. Not like you are steering anywhere far. Guy towing better be heads up that the one stuck isn’t a moron though.

Gotta think a piece of sheet metal would have ate up the hitch. Completely wrapped around it but probably on breaks your windshield.

Why's that? I never really thought about it much. I just always assumed a chain would be less prone to violent whipping failure than a cable.

Probably don't think about the hitch coming at you.

I read this story and immediately thought of that - this could have happened to almost anyone who had never given it any thought.

We think of these big metal towing balls as unbreakable - I have to admit I have never considered the danger of them simply breaking like that.

But, not sure I would have even tried to tow a vehicle out of mud where all four tires were spinning and frame was resting on the ground. Otherwise I could have been victim of this same disaster.

I wonder if they were trying to jerk it?

If you can’t get it with a straight pull, I always go get a tractor.

I got one of those stretchy bands that that ole baw in the desert uses. Let's you get some speed going and uses the elasticity in the band to pull them out.

That ball hitch had a huge drop. Probably would have been ok if it were a 2" drop but that one just bent and snapped. They actually should have tied to to the tow bar itself though.
I'm going to make it a point to never tie a tow strap around the ball regardless after seeing this.

I was always taught to put floor mats or towels or something to weigh down the rope to keep it from flying back if it snaps. Though I've never seen a tor hitch break.
I got a montero so stuck one time a big rig had to pull me out.

This big empty hole where metal should be is just one of the many issues with this failed recovery.

There’s nothing wrong with a hollow shank ball mount if you’re using it as intended, within its design load capacity.

In this case they obviously were not. Hindsight 20/20 and all, but seeing how deep that F-250 is, I can’t imagine thinking you’re going to pull it out with a strap looped on a ball hitch. Especially not a ball hitch with over a foot of drop.. that puts a shitload of torque on the shank AND pretty much guarantees it’ll fly upward if it breaks.

I think people severely underestimate the forces involved in something like that.

Got stuck hunting ducks on the east side of Toledo Bend. We would drive down a logging road and walk in, the lake was down around 5'. Come back and my buddies truck gets stuck, with 4 wheel drive. My buddy decides to walk back up the road to the highway and find a ride into town for help. Well he walks maybe 100yds and here comes a truck with a fellow and 3 kids in the cab. Looks like he was deer hunting from the truck. He drives down to us and its a 2 wheel drive, no luck. He says I'll be right back yall dont go anywhere. He comes back with a small tractor. Hook up the chain, no luck. He backs his tractor up and tries to jerk the truck out. The chain breaks and whirles above my head toward the tractor. If I didn't duck, my head would of been severed. Scary shite.

Some of y'all never had to do a shear and moment diagram and it shows

I was referring to the forces involved pulling a jacked up F-250 that’s sunk to the rockers, not necessarily the force required to shear the ball mount (which is obviously less, given the result).

Chinese steel?

ETA: obviously brittle fracture here. If the manufacturer takes the extra step and tempers the steel, the steel still breaks however a lot of the energy is absorbed in a tapered fracture and the guy lives.

Those people had no idea about anything they were doing.
That some evil mud they were in. That's the kind where you get a vacuum lock on everything and you can't break the suction.
I got a Bronco stuck in something similar once, not quite that bad though.. It was a nightmare.
It took about 18 hours of brutal manual labor, probably 20 bags of quikrete, a couple of railroad ties, 12 trips to an air compressor to fill up an air pig..
I never got in anything like that anymore.

Yep, that 'steel' appears to have been cast in an E Z Bake oven.

Never ever trust a ball hitch or much less a drop hitch for pulling out of mud. If you dont have a good yank or tow strap to connect to something better, use a come along hand held winch. This whole thread is tragic.

All steel looks like that when it breaks. Break any of it that way and see how it looks.

Need to attach to something that is pulling inline with the frame. That dumbass drop hitch is putting that receiver in a lot of bending, increasing the stress on the receiver tube. I'm pretty sure it was not meant for that. They make receiver attachments with tow hooks or loops or D-rings that put the stress directly inline with the receiver connected to the frame.

Maybe the link confirms, but my bet is he was trying to jerk that truck out instead of pulling steadily.

Sorry they made the mistake that costed a life. Recovery 101 says to put weight on the strap to absorb the energy. You miss this step, rebounds happen.
