Just purchased a New Holland Workmaster 50 and would like to utilize the built-in hydraulics for front end loader attachments. The FEL joystick has 2 red buttons that supposedly operates the optional 3rd set of hydraulics. The dealer has quoted me $1000 to add the necessary parts to make everything work. Has anyone done this? Can I purchase the parts to do it myself? I am not familiar with the terminology for the function that I am seeking. I would like to attach a hydraulic auger.
