We've designed all of our arena drags to give you as much control as possible while trying to properly prepare your arena. So the weight of the drag will change as you begin entering your arena with a full tank. You begin spraying, and by the end, your tank is going to be empty. So your footing depth is going to be inconsistent throughout the entire thing.Another issue to consider is that the water tank on the three point hitch is just simply not enough to cover your entire arena. You're gonna have to refill your tank, go back out there and re-water it because the tank is just too small on the three point drag.
