Hydraulic circuit for colter pressure adjustment at an agricultural spreading machine

A hydraulic circuit for colter pressure adjustment at an agricultural spreading machine, comprising:

• a first line region configured to be connected to a first colter pressure adjustment cylinder and to specify a hydraulic pressure to said first colter pressure adjustment cylinder;
• a first pressure limitation valve configured to limit the hydraulic pressure in said first line region to a first maximum pressure;
• a second line region configured to be connected to a second colter pressure adjustment cylinder and to specify a hydraulic pressure to said second colter pressure adjustment cylinder;
• and
• a second pressure limitation valve configured to limit the hydraulic pressure in said second line region to a second maximum pressure;
• wherein the second maximum pressure to which said second pressure limitation valve limits the hydraulic pressure in said second line region is dependent upon the hydraulic pressure in said first line region, and wherein said second line region abuts against a valve inlet of said second pressure limitation valve, and said first line region abuts against a valve outlet of said second pressure limitation valve.
