My wife is a barrel racer and needs to make a riding arena on our ranch in Oklahoma. The ground is rather heavy clay and gets rock hard and cracks under the hot summer sun but should serve as a good base. Currently the spot selected in fairly flat with good run off in all directions. Is there a single attatchment that could break up the sod, loosen the ground and also be used for general dragging prior to riding after the arena is finished? Could this same attachment be used for ranch road maintanance? We figure that once the ground is worked and the grass uprooted that we will have to haul in a layer of sand to cover it. I have a Mahindra 7520 70 HP 4 wheel drive tractor. Anyone with experience in this area suggestions would be appreciated.
