Abstract
A horizontal auger garden tilling apparatus and method of use having an outer frame, an inner frame which pivots with said outer frame, and a rotating auger capable of tilling soil to depth which conventional tillers cannot begin to reach. The apparatus is moved and the method of use is performed via attachment with a tractor or other movable carriage which provides enough horizontal force to move the auger through the soil and provides auger rotational power. A trencher attachment prevents auger soil refilling and allows the apparatus and method of use to be utilized and performed in conjunction with trenching operations.
Claims12
A horizontal auger tilling apparatus comprising:
- an inner frame having a left side, a right side, and a bottom side;
- and
- said inner frame pivotally mated and retained with an outer frame;
- and
- a gear box mounted with said inner frame, said gear box having an input shaft and an output shaft;
- and
- an auger having one or more flights and an auger shaft;
- and
- a bearing mount assembly mounted with said inner frame toward said bottom side relative to said gear box and having one or more bearing assemblies;
- and
- said auger shaft rotationally held with said bearing assemblies and said bearing mount assembly and coupled with said output shaft of said gear box thereby limiting any movement of said auger shaft relative to said inner frame;
- and
- said auger shaft and said auger flights extending past said bottom side of said inner frame;
- and
- said input shaft of said gear box capable of receiving a rotational torque from a rotational power source and transferring said rotational torque to said output shaft and thereby said auger;
- and
- said outer frame having a base having a shape capable of mounting with a movable carriage and said outer frame formed to allow a movement of said outer frame to move said auger laterally through one or more soils and said rotational torque on said auger capable of loosening the one or more soils;
- and
- said inner frame retained with said outer frame in a fashion that should said auger encounter an obstruction said inner frame pivots relative to said outer frame and thereby said auger rides over the obstruction;
- and
- said inner frame is retained with said outer frame with one or more pivot shafts extending from said inner frame and pivotally mated with one or more pivot holes within said outer frame;
- and
- a shear tab having a first leg and a second leg;
- and
- said second leg attached with said outer frame;
- and
- said first leg having a shear pin hole positioned near a shear pin receiving hole with said inner frame;
- and
- a shear pin or bolt through said shear pin hole and said shear pin receiving hole thereby allowing said shear pin or bolt to break should said auger encounter the obstruction and allowing said inner frame to pivot on said one or more pivot shafts.
