I just use a grading shovel and a wheel borrow. Dig up the high part, place you some pvc 6"-8"/gravel down at the low end... You use a pickaxe first to break up the redmud/clay and the quartz. Then shovel it out to the wheelborrow and dump it on top of your gravel/pipe.
The pipe prevents your water from pooling, I make my runs about 25'x25'. Then plant your fruit trees (mullberry and hazelnut does good in that fresh hard red mud you dug up) along the outside (to provide snacks/cover for hawks.
Hills aren't bad. IF you need more dirt, I got mine by digging into one of the red mud hills and dug out a root cellar. Use, used tires for walls support for free.
