My Mustang 332 has the lines with quick couplers under right boom, it does not have the 3rd foot pedal but the provision for one is there, I can rock/move the provision and it moves pivots and linkage on left side of machine, and feels to be spring loaded with a return to cent action. with out anything to plug in to for a test cylinder or other accessory, what would be a good way to know if it has an aux. hyds. I have a Meyer snow blade I cut down and made a mount for and would put an angle cylinder on it if it would work. any help is appreciated thanks
