Coca cola Guy is right about the soil compaction issue, plus better flotation over wetter soils and, believe it or not, a smoother ride.
I had a Steiger many years ago before being sold to Case. You had the option of Cummins or Cat power and auto or standard transmission. They came in three models, the cougar, the panther and the Tiger. The one I had was powered by a Cummins and had either a 20 speed or 16 speed transmission - it's been a few years so I'm not sure about which is right. They were a very comfortable machine, which is important when you spend 10 to 12 hours a day in them, and had plenty of power. Unfortunately, the planetary gears and wheels were of a poor design and I kept loosing the outside duals. I'm sure that problem has been corrected many years ago.
I went from Steigers to Versatiles, which were owned by Ford at the time, and never looked back. I was running Versatiles when I retired and sold things off 11 years ago.
As an aside, the John Deere dealer in Akron was one of their largest volume sellers of air seeders and they would often come in on flatcars - quite a sight.
Those wind turbine blades are manufactured south of Brighton, Colorado and you can get a very good view of them loaded and ready to roll from highway 85.
Coca Cola Guy is right, they're loaded butt to butt. The outside duals for the wheeled tractor will be installed after it's off loaded.
