I bought a older 743 Bobcat in good working cond and also bought a used grapple bucket for it. I replaced the hydro cyl and lines and couplings with new ones as they needed to be replaced. The bobcat had couple layers of paint on the old couplings and were gummed up meaning the aux hydro's haven't been used in a long time or at all. From what I've been told how to engage the auxillary hydro's is to push down on the button on the right stick and move the middle foot pedal. Could it be a air lock in the new lines? I doubt this because there is no engine lag when the button is pushed or when the middle pedal is used basically have no hydro pressure getting to the grapple. Any help would be much appreciated.
