Bobcat S175 lost it’s lift (up/down)

[Chiefoakes]

My most used equipment I us is my skid steer. His name is Bob. Anyway long story short, Bob instantly lost his up/down. I checked all the linkage from my foot pedal to the valve. I didn't see any issues that would cause it to just stop. Bob still has his tilt. Fluids are all full. I'm at a loss on what I should check next. Any suggestions before I take Bob to see a Doctor?

Can you drive it?

Can you drive it?

Yes, everything else is working except the up/down.

What model? Serial #? Do you have any Codes?

Possibly the load check in the control valve is stuck open. It is commonly located between the ports on the hydraulic control valve. If the tilt is strong, I would lean toward the load check.

If the tilt is weak and slow, I would go after the main relief first.

At idle does the engine labour when the lift circuit is activated? If so then I would think that the coil on the lock out solenoid has left the chat. I'm not sure how the S175 works but on my 763F one solenoid locks out both circuits, on your later model there could be a lock out solenoid on each circuit. My coil just threw the towel in the other day after a measly 26 years (lol) as a good coil should be 10 Ohms whereas mine was 1.4 Ohms.
Then again I could be barking at the wrong tree.
