I need some advice on a new box blade and tractor I purchased. The tractor is a M5140, 52hp, 4WD and the box blade is a land pride BB1572 rated at a maximum horsepower of 40 according to the operators manual. Now I'm wondering if I have the wrong box blade. I suppose worse case is the tractor bends or brakes the box blade since it has more power than the box blade was designed to handle. Do anyone have any experience or opinions as to what I may be facing? Thanks for any help.
