I love my BX and am totally impressed by what it will do......and I have operated tractors and machinery for years and know how to squeeze every bit of power and traction from them.............so I can not emagine why you want to put duals on a BX. Are your rear tires loaded? Have you added wheel weights? Is your FEL on or front weights added when you plow? There are many ways to get more traction than the BX can provide HP for without adding duals. Besides the BX look just look plain silly with duals. No matter how much traction you get you can not pull a 2 bottom plow or a 6 foot disk. You would be much better off with a 4' disk, see attachment, and a one bottom plow. You would be able to travel at a speed that would allow you to cover more ground faster than if you had the larger implements and were lugging and spinning the tires. Always remember, it is much better to have more tractor than implement not vise vera.
