US 5,862,764 A · Method and apparatus for a floating frame field harrow

Abstract

A method and apparatus for a harrow is provided, and more particularly to a harrow implement with a terrain following frame, able to be pulled by a tractor. The improved harrow includes a main frame that supports at least a floating frame on which harrowing blades are attached. The harrow blades follow the contours of a field or bed of soil, resulting in greatly improved tilling when compared to conventional apparatus used for this purpose. The harrow specifically suits the needs of a reduced tillage farming operation. The harrow is wide, yet the floating frames follow irregular surface contours, significantly improving the potential range of topography that can be farmed efficiently. The harrow can include a clod diverter to move or deflect clods to the irrigation furrows, away from the planting rows. It can also be customized in the field to handle the individual field's requirements, including tilling depth and seed row separation distances. The harrow can also incorporate a spray rigging that applies sprays onto the soil as it is tilled.

Dependent claims

A field harrow comprising:

a main frame configured substantially parallel to a ground surface, the main frame having a front bar rigidly connected to a back bar by at least a single running support, the front bar having a lead bar support rigidly attached and substantially perpendicular to the front bar, extending downward, the back bar having a trail bar support attached to the back bar and substantially perpendicular to the back bar, extending downward, the lead bar support connected to a lead bar, the trail bar support connected to a trail bar;
and
at least a single floating frame, the floating frame including a plurality of floating frame runners, and at least a single harrow blade, each of the floating frame runners having a lead end and a trail end, the floating frame runners having a substantially parallel configuration relative to each other, each of the lead ends hingeably connected to the lead bar and each of the trail ends connected to the trail bar, the trail bar connected to two neighboring floating frame runners, and the harrow blade mounted on the trail bar so as to contact the ground surface.
