The Influence of Velocity and Disk Angle on the Kinematic Parameter A of Disks
TLDR
In this paper, the kinematic parameter A, the ratio of rotational velocity to forward velocity, of experimental disks was studied as a function of change of disk angle and disk velocity Disks with reduced back pressures rotated more rapidly than the conventional spherical disk.Abstract:
THE kinematic parameter A, the ratio of rotational velocity to forward velocity, of experimental disks was studied as a function of change of disk angle and disk velocity Disks with reduced back pressures rotated more rapidly than the conventional spherical disk The absolute velocity of a point on the edge of a rotating disk has a cosinal nature, the minimum velocity of which is at the lowest underground point of the diskread more

Performance of Free Rolling and Powered Tillage Discs
TL;DR: In this paper, the benefits of driven tillage disc by an external power compared to the conventional free rolling disc under controlled experimental conditions were evaluated in the soil dynamics laboratory of Faculty of Agricultural Engineering, Kasetsart University, Kamphaengsaen Campus, Thailand.

Soil compaction reduction with a modified one-way disker
TL;DR: In this article, a modified one-way disker (MOD) was used for both fall primary and spring secondary tillage, and a split-plot field layout was established on a Sainte-Rosalie clay with subsoiling (or without) as main plot units and tillage treatment combinations as subplot units.
Techniques to diagnose plow and disk pans
Y. Chen,S. Tessier +1 more
TL;DR: In this paper, Chen et al. used statistical confidence interval comparisons of soil bulk density (Ph) or cone index (CI) at two reference depths, one above and the other below the bottom of the tilled layer, to diagnose mechanically induced hard pans.

Disc angle and tilt angle effects on forces acting on a single-disc type no-till seeder opener
Mehmet Zahid Malasli,Ahmet Çelik +1 more
TL;DR: In this article, the effect of the angle of the disc on the impact of the forces on the horizontal (draft), side and vertical forces are divided into two as the disc and tilt angle.
