I really like that Cub. Those Vreidestein tires are the best looking tire for a garden tractor. You definitely need a lot of weight. Try to find a way to put about 50% more on the left side, unless you just want to sit on the edge of the seat when in the furrow. Does that tractor have a lower range? It looks a little fast to me. With the right power and weight, you should be able to go 6" deep with a 12" plow. It sounds like you have plenty of power to spare.
Lawn is looking tight in the background. I enjoy stripes for whatever reason.
