Here is how I welded a couple grab hooks on the front of my backhoe. The rear has good attachment points on each side.
Everything I haul frequently I have chains cut to the exact length needed usually only 4-5' long so they are not as bulky and are easier to work with. I can chain stuff down in a hurry for sure.
Going from the four corners out is best but I do have a trailer that I haul two kubota RTV's on and they are so close together and near the ends of the trailer so there is no room to go from the corners out so I go from the corners in. There is a d ring on the trailer on each side positioned between the midpoints of the tires. I hook a chain on the frame of the RTV's behind the tires and run it two the d ring. Four chains on each one.
