Header float system for use with an agricultural windrower or combine

摘要

An agricultural harvester includes a traction unit (12) and a crop harvesting header (14). A right hand gauge wheel (68) is movably coupled with the right hand side of a main frame (60) of the header (14), and a right hand hydraulic cylinder (70) coupled with a first hydraulic circuit (76) is coupled between the right hand gauge wheel (68) and the main frame (60). A left hand gauge wheel (68) is movably coupled with the left hand side of the main frame (60), and a left hand hydraulic cylinder (70) coupled with second hydraulic circuit (78) is coupled between the left hand gauge wheel (68) and the main frame (60). A third hydraulic circuit (80) is coupled with a vertical position hydraulic cylinder (26, 48, 74). All hydraulic circuits (76, 78, 80) are independent from each other.
