I assume they're pulling the wheels off and blocking it? Can't be done with wheels on, requires outriggers anyway to do that.
Always did them on a RGN, most are 10' high or more, I think on a step deck that would be a pucker factor of a high 7 for my taste. 5 or more on the pucker factor means new seat.
I've seen guys do it, just wondered if anyone on here had, a harvester I used to work for is going to have me pick up at least 1 of his 7 new machines, my deck is 37" figured I'd be about 14 T and 11'11" wide, no different then the occasional load of J&M grain carts
I would check into it further. First, I believe they now ship all combines minus the wheels/tires. An RGN is still necessary. I would think you would be much taller than 14' high. Second, the factory may have a rule against this. For example, the factory in Waterloo will not let you leave if you exceed 14'4 high. Doesn't matter if you are will call or contract carrier. I don't haul combines, so I am not sure on the specific requirements at JD Harvester. I would just be surprised if you were able to haul a combine on a step. If you need more information, PM me and I will forward you contact information for the shipping department.
Friday I sat and looked at least half a dozen or more JD combines loaded up on a step-deck. enough so, I called a buddy up with the information who runs a step.
I have a hard time believing they would be shipped on a step deck. All I am saying is make sure you have all your ducks in a row before bouncing in to Moline for a load you can't haul.
I have seen a few on step decks, but the over height just makes me shaky. 16 or 20 feet wide does not phase me, but for tall thing-a-ma-bobs I would stick to a RGN. Never hit anything overhead but one time and it was nothing more than a light street light cable, no one hurt but boy the crowd it gathered. Fire trucks and cops, local news paper. Only saving grace, the city permit routed me and they gave a green light.
