Wait wait! Don't write up the obituary yet! I'm here! lol
Yes my hitch is still attached to my 4106 and it still hauls my car trailer around with zero issues for the last 8 years.
I'll search for the link. I think the pictures are still uploaded......
The above picture shows 99% of it. The hitch actually pushes up on the engine cradle, enough to deflect the receiver about an inch. The receiver tube has a solid 2x2 steel center that 4-5 feet long and goes through the middle of the round 8" diameter 1/4" wall tube that goes from side to side.
Oh yeah, I found them. They're still online.
These pictures pretty much sum it up. All the push/pull is off the engine cradle, the receiver tube is pushing up the engine cradle by some unknown amount of force to counter the downward dynamic force and tongue weight. I do use a weight distribution hitch, and as little tongue weight as possible without affecting the way the trailer tows.
It works, it's heavy duty, and I was told it couldn't be done. And you know, it wasn't even expensive. I got almost all the metal from a recycler.
