My high pressure hydraulic line is leaking at the swivel union. When I change it out will I have to purge the air out? I can't believe this line is leaking. My Silver Eagle 2744 only has 120 hours on it.
Yes, air will have to be bled from system. First check your records & see if mower is still under warranty, if it is don't touch it, take to dealer & let them replace hose & bleed system.
