I agree that chaining the FEL and bush hog is not needed for load securement, but some if not all states require that any attachment be chained separately. I use ratchet straps across my FEL and even strap the back hoe bucket to keep it from moving even though it is pinned and couldn't possible come off.I am very pleased with the fit on the deck with the mower on the tractor. I agree with dropping the chain hook through the stake pocket. I usually chain to the front of the trailer 1st with ratchet binders and then use the binders at the rear to pull everything taught. The loader and the mower deck don't really need any extra securing to the trailer. I could use the winch on the front of the tractor too but it is not on it most of the time.
