I used to sell commercial accounts for a dealership, so most every day I had either a CUT, SSL or both aboard. Three inch ratchet straps (10,000# as I recall) work well for a lot of applications, but you can cut them up in a hurry if you're not careful. The trick is to use a generous chunk of doubled or tripled carpet scrap where the strap contacts the equipment. Chain through a clevis on the drawbar is bulletproof for the rear of a tractor. I prefer the ratchet style chain binders, as you can REALLY torque 'em down! It's important to triangulate your tie-down points to prevent movement fore and aft as well as side-to-side. As always when trailering, make sure you have at least 12% of your total loaded trailer weight on the ball.
