描述This book examines and evaluates the performance of four standard chisel plough tines: heavy duty, double heart, double heart with wings and duck foot, which were connected with a rigid shank. Experiments were conducted in a soil bin filled with sandy loamy soil, and the experimental factors included varying operation conditions (speed and depth) and their dependency upon a draft force and their components (horizontal and vertical force), specific force (force per unit area), specific power (power per unit area), soil loosening percentage (above and below the original soil surface) and soil profile parameters (e.g. furrow height, furrow width, ridge height, area of ridge and furrow etc.). The evaluation involved developing regression equations based on Glancey and Upadhyaya’s model by adding new terms related to the tine geometric parameters or by adding a dummy term variable. These two techniques made up the general study parameters and had the same trend effect on operation conditions to compare between tines. Lab results such as force components and the width of furrow were verified in a field test. Furthermore, a model to predict the draft force by using principles of soil mech

Introduction,lanting in the soil. Generally, tillage is bounded to the arable soil, which involves organic matter and is limited to a depth of about 10 to 90 cm. Another objective of tillage is to improve the soil’s physical properties, for example weed control etc. (Stout & Cheze 1999).

Einheiten und Symbole für IngenieureThis chapter is divided into two main sections. The first section presents background on forces acting on the single tine, a brief illustration of the most famous draft force analytical models. The second section is related to the soil profile parameter.
