I have a bx2370 that I bought primarily for removal. I got the fel and the bx5455 snowblower. I also bought the ballast box but only attached it today for the first time. I have done some light loader work without the ballast. So, I don't really care for the extra length and clumsiness of having the ballast box on the back. Is it necessary to have a ballast box for the heady duty snowblower? Also, if I used the fel to stack some snow,miss it necessary? Of course I will use the ballast box if I ever do heavier loader work.many input would be appreciated.
