6 ft hog is laughable for a 4520 HP-wise. No problem! Depending on the weight of the unit make sure that you have some weight on or in the wheels and maybe some weight on the front. A heavy duty 6 or 7 foot brush hog can make the front REALLY light without any weight.

I don't have any experience with a tiller on mine but I suspect that you would need some weight on the front for a 74" tiller.
