It's almost twice the weight of the tractor you show "on order," and WAY WAY more than your Bota. Another factor is that you won't have the electric brakes when hooked to a tractor. Even if it is equipped with surge brakes, they won't work backing up or going up a steep grade.
Be very careful pulling that dump trailer. Years ago, I lost a cousin pulling a heavy manure spreader behind a tractor. He went down a slope with it loaded and tried to turn. It jackknifed and flipped the tractor, killing him.
