Calibration of baler tailgate cycle speed

1. A method of performing a tailgate calibration to control the speed of a tailgate for bale ejections from a baler, the tailgate moveable between a closed position and an open position, the method comprising:

via one or more controllers coupled to the baler and configured to control movement of the tailgate, setting factors relating to flow rate and speed for opening and closing the tailgate to system nominal values;

opening the tailgate by the one or more controllers based on an open command from an interface coupled to the one or more controllers until a stop command is received by the one or more controllers;

closing the tailgate to the closed position by the one or more controllers based on a closed command from the interface; and

storing an open time associated with a time taken to open the tailgate until the stop command is received and a closed time associated with a time taken to close the tailgate to the closed position.

2. The method of claim 1 , wherein the factors relating to flow rate and speed for opening and closing the tailgate comprise one or more of: (i) a normal hydraulic flow rate for opening and a normal hydraulic flow rate for closing the tailgate; (ii) a baler tailgate opening speed factor and a baler tailgate closing speed factor; and (iii) a calibration hydraulic flow rate for opening and a calibration hydraulic flow rate for closing the tailgate.

3. The method of claim 1 , further comprising, prior to opening the tailgate:

via the one or more controllers, setting a tractor connected to the baler at operational levels; and

verifying closure of the tailgate by the one or more controllers.

4. The method of claim 1 , further comprising:

initiating an open timer when the open command is received by the controllers; and

stopping the open timer when the stop command is received by the controllers;

wherein the one or more controllers determine the open time based on the open timer.

5. The method of claim 1 , further comprising:

initiating a closed timer when the closed command is received by the controllers; and

stopping the closed timer when the tailgate reaches the closed position by the controllers;

wherein the one or more controllers determine the closed time based on the closed timer.

6. The method of claim 1 , further comprising, after the stop command is received:

moving the tailgate to a fully open position by the controllers.

7. The method of claim 1 , wherein the stop command is a command received from the interface.

8. The method of claim 1 , wherein the stop command is based on a determination from the one or more controllers that the tailgate has reached a predetermined open position.

9. The method of claim 1 , wherein the open time and the closed time are subsequently used by the one or more controllers to facilitate a bale ejection sequence.

10. A baler control system for a baler for performing a tailgate calibration to control the speed of a tailgate for bale ejections from the baler, the tailgate moveable between a closed position and an open position, the baler control system comprising:

one or more controllers coupled to the baler, the one or more controllers configured to:

control movement of the tailgate;

establish factors relating to flow rate and speed for opening and closing the tailgate to system nominal values;

open, based on an open command from an interface coupled to the one or more controllers, the tailgate until a stop command is received by the one or more controllers;

close, based on a closed command from the interface, the tailgate to the closed position; and

store, at a memory device associated with the one or more controllers, an open time associated with a time taken to open the tailgate until the stop command is received and a closed time associated with a time taken to close the tailgate to the closed position.

11. The baler control system of claim 10 , wherein the factors relating to flow rate and speed for opening and closing the tailgate comprise one or more of: (i) a normal hydraulic flow rate for opening and a normal hydraulic flow rate for closing the tailgate; (ii) a baler tailgate opening speed factor and a baler tailgate closing speed factor; and (iii) a calibration hydraulic flow rate for opening and a calibration hydraulic flow rate for closing the tailgate.

12. The baler control system of claim 10 , wherein the one or more controllers are further configured to, prior to opening the tailgate:

set the tractor at operational levels; and

verify the closure of the tailgate.

13. The baler control system of claim 10 , wherein the one or more controllers are further configured to:

initiate an open timer when the open command is received; and

stop the open timer when the stop command is received;

wherein the one or more controllers determine the open time based on the open timer.

14. The baler control system of claim 10 , wherein the one or more controllers are further configured to:

initiate a closed timer when the closed command is received; and

stop the closed timer when the tailgate reaches the closed position;

wherein the one or more controllers determine the closed time based on the closed timer.

15. The baler control system of claim 10 , wherein the one or more controllers are further configured to, after the stop command is received:

move the tailgate to a fully open position.

16. The baler control system of claim 10 , wherein the stop command is a command received from the interface.

17. The baler control system of claim 10 , wherein the stop command is based on a determination from the one or more controllers that the tailgate has reached a predetermined open position.

18. The baler control system of claim 10 , wherein the open time and the closed time are subsequently used by the one or more controllers to facilitate a bale ejection sequence.
