Hey all!
I'm new to this forum and have been searching several sites for the answer to my problem I'm having with the lift function on my arms.
A bit about my machine... 1999 with 2,800 hours and normal flow aux hydraulics.
Pre-work. Hydraulic fluid full and looked normal with no major leaks noted.
Was using my grapple in the woods for a few hours clearing and piling brush.
Had the arms about half way up and pushed the pedal to raise it higher and the arms began to free fall until I went neutral on the pedal (then it stopped). Pushed up again on the pedal and it continued to fall. Now it is resting at its lowest position and will not go up. The pedal linkage feels normal and I can hear the actuator and hyds working when I press the pedal up, but the arms do NOT move. Tilt works normally and the aux hyds work fine as indicated by normal opening and closing of the grapple. Of note the aux hyd control switch is in the neutral position. Left and right skid steer movement is normal and is NOT laboring when moving (normal normal). The hyds are NOT under load (engine idling normally) with the lift pedal in the neutral position. I am not seeing any fluid leaking under the seat or around any of the hydraulic cylinders. No codes are set and the control/safety panel lights are all normal. When I shut the bobcat down and parked it I checked the hyd fluid immediately and noticed the level was normal, but the fluid looked "milky". I topped off the hyd fluid a few weeks back and it was changed 4 months ago.
Checked the fluid and started the Bobcat a few days ago and it still will not lift.
I've checked a few other forums and my situation is slightly different than all of them. The closest I could find was a 2005 S175 that was having lift control issues, both up and down, but it was setting a code. In that post he swapped out a few valves on the back side of the hydraulic control block (not sure if that is the exact nomenclature as I am struggling to refind the post) that sits directly underneath the right side of the seat (as you look forward in the normal seated operator position). Update: Found the link...

I am somewhat of a novice when it comes to mechanics, but I have changed hydraulics lines that were wornout after I first purchased the bobcat a year ago.
Thanks for the help!
