Abstract:
1. A round baler comprising: a baling chamber having a tailgate in a rear section of the baling chamber, the tailgate being moveable between a closed position wherein the tailgate extends along a back side of the baling chamber and an open position wherein a completely formed bale can be discharged from the baling chamber; an actuator connected to the tailgate so as to be capable of moving the tailgate between the open position and the closed position; a baler controller configured to calculate a desired flow of pressurized fluid to the actuator and opening and closing times from an available fluid flow rate from a source of pressurized fluid, the baler controller configured to transmit through an electrical connection the desired flow of the pressurized fluid to an additional controller such that the baler controller and the additional controller are configured to control the desired fluid flow to the actuator by controlling a position of a flow valve located in fluid communication between the actuator and a source of pressurized fluid; and an activation device manually activatable to commence an open cycle and a close cycle of the tailgate, wherein the baler controller is programmed to open the tailgate in an opening cycle at a first rate of speed during a first predetermined period of time and to continue opening the tailgate at a second rate of speed slower than the first rate of speed during a second predetermined period of time.
