A system and method for managing the electrical control system of a header flotation and lift system of an agricultural harvesting machine, particularly one using only once fluid cylinder in connection with each respective side of the header, which system and method, in addition to executing header
A system and method for managing the electrical control system of a header flotation and lift system of an agricultural harvesting machine, particularly one using only once fluid cylinder in connection with each respective side of the header, which system and method, in addition to executing header raise and lower commands, provides several automatically executable operating modes for the flotation and lift system, including a wake-up mode; a normal mode, which can include float; a charge accumulator mode; a transport mode; and a header remove mode, and the ability to seamlessly and easily transition between the modes.

What is claimed is: 1. A method of managing a lift and flotation system interconnecting a header and a frame of an agricultural harvesting machine, comprising: providing a programmable controller in operative control of the header lift and flotation system, the controller being automatically operable in a normal mode for controlling the system to raise the header when a header raise command is present, for controlling the system to lower the header when a header lower command is present, and for setting a flotation force of the system equal to an inputted value therefor; providing a device controllable by an operator for inputting a selectable value for the flotation force to the controller, including a value of zero or about zero and at least one value greater than about zero; wherein responsive to an inputted value for the flotation force being zero or about zero, the controller will automatically operate in a header remove mode to control the system to hold the flotation force at the inputted value of zero or about zero, including when the header raise command is present; and wherein the controller will automatically raise the header to a predetermined elevated transport position when at least the following conditions are present: the machine is operating in a high speed range; and a speed of the machine is above a predetermined level. 2. The method of claim 1, wherein when in the header remove mode, if the header raise command is present, the controller will control the system to raise the header while holding the flotation force at the inputted value of zero or about zero. 3. The method of claim 1, wherein when in the header remove mode, when the header lower command is present, the controller will request operator confirmation thereof, and if the confirmation is received, then execute the header lower command. 4. The method of claim 1, wherein when initiating or in the header remove mode, if a park brake of the machine on, the controller will automatically hold the flotation force at the inputted value of zero or about zero for a predetermined time period. 5. The method of claim 1, wherein the device controllable by an operator for inputting a selectable value for the flotation force to the controller comprises a float switch. 6. The method of claim 1, comprising a further step of automatically operating the system in a float mode when the header is in the elevated transport position. 7. The method of claim 6, comprising a further step of automatically changing the operating mode of the system from the transport mode to a normal mode responsive to presence of either of the following conditions: the machine is no longer operating in the high-speed range; and the speed of the machine falls below a predetermined value. 8. The method of claim 7, wherein the predetermined level is about 10 mph and the predetermined value is about 5 mph. 9. The method of claim 1, wherein during a period of inactivity, if a header raise command or a header lower command is received, the controller will automatically control the system to increase the flotation force to a predetermined level.
