My in-laws have a large "farm" (10+ acres I believe) and they built a house on a set-back portion of the property. They had to get stone and rock brought in for their driveway, similar to yours.

And they own a skidsteer (since they did most of the work of clearing their property themselves). It's such a fun and handy piece of equipment to own on a large piece of property!

Best of luck with getting your driveway completed!
