When to Use Subsoiler?

A subsoiler or flat lifter is a tractor-mounted farm implement used for deep tillage, loosening and breaking up soil at depths below the levels worked by moldboard ploughs, disc harrows, or rototillers.

When should you use a subsoiler?

Another common use for a subsoiler is to cut the roots of trees and hedges that lie along the edge of a fence line or between one property and another. The subsoiler will cut those roots beneath the surface and help control the size of the hedge row by not letting it draw moisture from your pasture.

How deep should you run a subsoiler?

Ideally, the shank's tip should run 1 to 2 inches below the compacted soil layer. If the shank's tip is too deep, subsoiling may increase compaction because the compacted layer will not be fractured.
