A subsoiler is a type of tillage implement that’s used to break up compacted soil in an effort to improve the setting for growing crops. Frontier subsoilers can be attached to John Deere equipment to penetrate 24 inches into the ground, which is an idea depth for ripping tree roots in a treeline as well as ripping hardpan in a trail. A compact utility tractor is best-suited to haul and host the subsoiler attachment.
