1. A self-propelled agricultural vehicle comprising:

  • a chassis supporting a cab and having wheels for moving the self-propelled off-road agricultural vehicle;

    an application system supported by the chassis and including at least one storage container storing a volume of product for delivery on to an agricultural field;

    a hydrostatic drivetrain system for delivering power to the wheels and including;

    an internal combustion engine supported by the chassis,a hydrostatic pump system receiving torque from the internal combustion engine and converting the torque from the internal combustion engine into hydraulic power for use by the hydrostatic drivetrain system, the hydrostatic pump system including an input being operable by an operator in the cab of the chassis to control operation of the hydrostatic pump system, andhydraulic motors receiving hydraulic power from the hydrostatic pump system and arranged for delivering power for rotating the wheels, wherein each hydraulic motor has an inlet side receiving hydraulic fluid into the hydraulic motor from the hydrostatic pump system for driving rotation of the wheels and an outlet side releasing hydraulic fluid out of the hydraulic motor toward the hydrostatic pump system;

    a joystick provided in the cab, the joystick having a grip and buttons being operable by an operator in the cab of the chassis to control various functions of the application system; and

    a Human Machine Interface (HMI) provided in the cab, the HMI including a joystick selector and a hydrostatic pump system selector;

    wherein;

    the HMI is configured to enter a joystick calibration mode in response to selection of the joystick selector by the operation, the HMI being operable in the joystick calibration mode to calibrate the joystick of the self-propelled off-road agricultural vehicle in response to an input to the joystick by the operator in the cab of the chassis; and

    the HMI is configured to enter a hydrostatic bump system calibration mode in response to selection of hydrostatic pump system selector, the HMI being operable in the hydrostatic pump system calibration mode to calibrate the hydrostatic pump system of the self-propelled off-road agricultural vehicle in response to an input to the hydrostatic pump system by an operator in the cab of the chassis.
