Steering stiffness in my 2007 L3400 hst

[bota dude]

Hello guys, new member here. Recently I experienced the steering on my tractor to be very stiff as if I lost all power steering. I used the tractor for a couple of hrs. & came back to it a few hrs. later when the power steering was completely gone. I didn't see anything binding the steering rods nor any fluids dripping. Thanks to the forum for the oportunity. Any advice would be much apreciated!

for my L2800, the curly hose right next to the brakes was cracked and sucking air. Kubota technician stated this is a common Kubota fault. I replaced the hose, left it about 3/8" higher than factory installation which keeps the pressure off the bent part of the hose. Lost about 1/2 cup of fluid and my steering does not meet any resistance now, and as well, the 3-point hitch works more smoothly.
