Question is this. I tow a Cat 246 with tracks on a regular basis during snow season. The machine weighs aprox 9000 pounds with out the trailer. I have 2 chains with hooks for the rear and usually one chain with a binder across and through the front. I know the DOT wants one on each corner, but can someone explain to me why attaching equal length chains at the rear, pulling forward to get them tight then wrenching down the front of the machine is not as good as binders in the back ? It always seems that binders do not stay as tight as latching and using the machine to tighten a length of chain.
