I use 4 ratchet straps rated at 3300 working load, 10k breaking. They came as a set of four along with four straps with eyes used to wrap the axle tie points. Even with a wear guard, as others have said you need to be careful about any potential rub spots, as the straps can't take *any*. My tractor was delivered on a long haul in a enclosed car trailer. Insufficient (imo) d-rings, poor layout, you name it! Its a good thing the hauler never needed to stop fast, because he only had one strap anchoring the back, and it had abraided through! So much bad couldhave happened, but luckily only some paint had been rubbed from the top of the hoe, as it was rubbing on the wall of the trailer- the whole rear end of the tractor had shifted to the side. Straps or chains, SAFE WORKING LOAD, attention to proper placement, and frequent checking your load.
