Abstract:
1. An adjustable height implement system for an agricultural vehicle comprising: a harvesting implement having an adjustable height; a control system operably connected in a first operating mode to the harvesting implement to automatically adjust the height of the harvesting implement with respect to the ground based on a detected height of the implement from the ground determined from a height sensing system; the control system is operably connected in a second operating mode to the harvesting implement and programmed to determine the height of the implement from the ground using the height sensing system and maintain at least a predetermined distance between the harvesting implement and the ground wherein when the second is engaged and the height is less than the predetermined distance, the control system automatically raises the implement to a first position with respect to the vehicle that is at or above the predetermined distance and the implement is held in the first position while the control system remains in the second mode and the implement height is greater than the predetermine distance; and wherein the second operating mode being engaged in response to the agricultural vehicle satisfying at least one predetermined vehicle operating parameter.
