Abstract
The working depth of obliquely angled disc gangs on the implement can be readily adjusted from the tractor seat with a single hydraulic cylinder through the use of mechanical linkage that couples the hydraulic cylinder with all of the disc gangs for simultaneous movement. Special pivots that join the gangs to the main frame permit the gangs to be manually angled adjusted without affecting depth, and vice-versa, while quick-release locks securely hold the gangs in their selected angular positions yet permit rapid adjustment.
