Here is more of a real answer. However it's not using a hydro, which will never equal the same energy transfer as that of a all-gear IH Cub Cadet.
I towed an estimated 2000 + pound yard roller with my model 71 with k161AS. There was never any made up broken bolts in the rear plate cover. As a matter of fact, the yard roller pressed down on the draw bar and bent it down.
Real life experience. IH Cub Cadets are number one. Fact!
