The reason I only made them about 12 inches is that the longer they are the more chance of diggin a groove into somebodies nice new ashpalt driveway. Since I do quite a few drives in the winter I wanted to stay on the conservative side.
Also I only need the extra capacity to pull snow away from a building or car so that I can back up over it and blow it forward.
Any longer and the 3/8 steel plate would have needed a brace (again wanted to avoid)
Also with wet sticky snow and the
b2920 not being overly heavy I was a little concerned about traction (didn't want to go to chains because of the paved driveways again)
The b series fits my needs nicely and gets in and around objects like cars without being too cumbersome and without giving up too many comforts and hp.
This modification would work fine for top soil/sand/gravel but probably would not use for anything heavier like grading since I would not want to bend or warp the blade itself.
