I suggest being careful about burying anything as some property sales agreements make you disclose anything about the property that is not visible to the buyer. Those little secrets can cost you big time down the road as you may just find yourself defending against a lawsuit in the future.

If I had that problem I'd call a local earthmoving contractor and pay the $140 an hour for a full size trackhoe (like a Hitachi 200) to come and bury the pile for you. It'd only take them an hour or two, and you can sit back with a beer instead of breaking your back and your tractor doing it yourself.
No, I don't really need the area, but the mound just looks funny, unnatural and out of place. Now that I took all the dirt off it, it does look like an ancient burial mound. I do know a contractor with a big track hoe that could make short work of it, but his mobilization fees just to come here, before he even starts his track hoe up, is more than I would want to pay. I could dig a hole beside it. bit it would be a big hole, and besides that my tractor wouldn't have enough "umph" to even begin to push it in. I guess it will stay there for now and I will try to consider it attractive
