Abstract
The present disclosure generally provides systems for adjusting tension and positioning of a harrowing chain. Systems may include a tension adjustment assembly, and the tension adjustment assembly may include a pivot assembly and/or a cylinder hydraulic assembly. Modifications also may be made to the frame of an agricultural implement to address transport issues related to harrowing chains. Further modifications to exterior harrowing chains may be made to reduce the number of small ditches formed in a field due to digging by harrow disks of the chains.
