It entirely depends on where in the system the replaced hose was. If it was on the suction side of the pump, there may be trapped air that needs to be purged before the pump will start to pump again. If on the pressure side, it would not cause what you describe. Another thing is if the controls are pilot valve operated and the pilot system got air in it, it would need to be bled out. You may need to contact the service department at a dealership and ask for some help.

What hose was changed? Check the main pump hose, bleed it or your pumps aren't in sync.The pressure won't let your hydraulics work

Yes , is quite necessary. How would it work with air in there? Will need to bleed the system, and to do so, will have to cycle the controls back and forth till you get the air out of the actuator that your trying to move. Good luck.

Just like anything, you have to get the air out for the hydraulics to work. Air compresses and liquids don't. there in lies the difference.
