Study on a Plow to Invert Furrow Slice at the Same Position (Part 1)

The Concept of a New Plow and Some Experiments on Inverting Furrow Slice

Abstract

Conventional moldboard plow inverts a furrow slice with transverse displacement. Therefore, secondary tillage must be performed after plowing to even the field surface. This paper describes a new inverting moldboard plow which inverts furrow slices at the same position. The fundamental characteristics of the new inverting plow are as follows:
(1) furrow slices are completely inverted at the same position with no transverse displacement.
(2) the plow is simple in structure and easy to operate.
(3) tillage depth is uniform and hard pan is flat.
The new plow was symmetrically constructed with shares, moldboards, and side pressure boards which were perpendicularly fixed to the moldboards. The furrow slices are turned by the mouldboard while changing the direction of flow by the side pressure board. Some experiments in laboratory showed that the furrow slice was sucessfully inverted at the same position.
