1,000lbs., what size is that? 2 man or higher or what? There are many options, just depends on the situation. If you have room, get a large backhoe or loader, if you don't then, you have to become creative. I don't know rocks in lbs., not that good yet, but I'm okay with names like 1 man etc. If they're not that big, get an industrial bucket attachment for a skidsteer.
