Subsoiling brush cutter hitch

Abstract

A subsoiling brush cutter hitch adapted for receiving a mower, a subsoiling shank, and optionally a coulter blade, enables combining activities for two dissimilar resource management practices, mastication (mowing) and subsoiling.

AI Technical Summary

Benefits of technology

[0011] We have now devised a combination subsoiling brush cutter hitch that enables combining activities for two dissimilar resource management practices, mastication (mowing) and subsoiling. The objective of mastication (mowing) is to reduce organic matter (live or dead vegetation) in an area for various purposes. The objective of subsoiling is to improve soil productivity by reducing soil compaction which in turn improves soil tilth. The hitch is designed to be compatible with many existing manufactured mastication / mowing heads and incorporates a subsoiling shank and wing, and optionally a coulter blade for cutting through organic material.

Problems solved by technology

Each of these pieces of equipment can produce its own soil impacts or accelerate existing soil impacts.

Subsoiling has been proven to increase the survival and growth of seedlings in areas of previous compaction, but since there is a high cost associated with subsoiling, it is considered only after multiple planting failures and determination that a hardpan has indeed developed.

Once a site has been replanted multiple times and has experienced surface losses of nutrient-laden soil, efforts to vegetate the area with desired stock may be greatly impaired regardless of renewed soil infiltration.

This approach to subsoiling reduces compaction, but does not allow return of organic matter of varying size to the soil.

Also, mats of organic matter tend to accumulate under the agricultural implement, resulting in a loss of organic matter from the soil surface.

Carelessness during the dozer subsoiling operation can also result in accumulation of rocks and boulders on the surface.

Moreover, the pivotal mount of the ripper to the back of the bucket is susceptible to eventual stress failure.
