The hydraulics have check valves in them when the wheels are down so if you lose oil going down the road the frame will not go down. There is a pin on the drop down hitch however.
Does that by chance have a manual override system where you can just pump the hydraulics by hand manually? (possibly in owners manual) Not sure how that system is on there, but some systems like that do, for such problems like you have. Good luck.
Yes it was the same for me BACK IN THE DAY. Back in the day it was said face to face,and settled on the spot, good or bad, not on some social media where you can hide miles away.
