I’ve got a B2650 with 110 hrs. I started it yesterday and let it warm up until 1 bar showed on the temp screen. When I went to raise the 3 point hitch it wouldn’t move the FEL moved fine. The hydraulic fluid was at the right level on the dip stick. I checked all my fluids before I started it. Finally after a few tries it did move. Slow but it did move. And worked fine the rest of the day. But it was slow in raising. I’m a new tractor owner so any help is appreciated.

Was it both lifting and lowering that was a problem or only lifting?

There is a knob behind your legs as you sit on your seat (calf level) that adjusts 3pt speed, any chance you may have turned that knob? Not sure if that could cause it to completely stop but I know my old tractors when I turned that all the way down the 3pt was very slow.

Just raising it. I I used the FEL the rest Of the day But whe I parked it in my yard and let it down it went slow. A couple hours later I went to move it in the shed and it went up fine. Just slow. I know the fluid has to warm up. But it was at 1 bar and thought that would be warm enough

@JustinB60 is correct about the knob controlling 3 point drop speed but it doesn't impact lift speed. Do you know if the tractor had its 50 hour service? If not, it's possible the the filters and fluid have break in contaminants in it. If the service has been done, the filters should be white instead of gray.

Yeah the 50 hr service was done. I did it myself. And it’s worked fine since except for yesterday. The service was done about a year ago

Do you have a backhoe by any chance or have you reinstalled the loader recently?

I do have a backhoe but it’s been off for a few months. I did take my bucket off and put the grapple on. But that was a couple weeks ago

Try disconnecting, cleaning and reconnecting the power beyond/backhoe quick connect as well as the 3rd function quick connects and report back if that corrects it.

I just cleaned the 3rd function fitting and it seems to be working fine. I let it warm
Up to 1 bar on the temp gauge and worked it several times and it worked fine. Thanks for all the help

I had the same issue come up all of a sudden while working with my B2650 in heavy brush. The 3-point stalled out while lifting, and the hydraulic fluid level was fine. It drove ok with no other symptoms so drove it home to diagnose the cause.

There was very little rise of the lift arms when the lever was operated. The arms descended normally when lowered. Couldn't find anything wrong! UNTIL I looked REAL close at the hose quick-connector on the tractor for the hydraulic line that is used for the backhoe hookup. I am guessing that a stick had bumped the quick-connect release ring JUST enough to release the hose male end slightly without the hose coming free of the connector. The connector lock ring was nudged back maybe 1/8" max and was quite hard to see being loose. I snapped the hose properly into place and the 3-point sprang back to life!
Was bigly worried that the 3-point or hydraulic pump system was screwed. Not a nice sensation.
All's good now! Keep an eye on that connector!

My photos show the properly connected and the loose quick connector. Kinda hard to see the difference, especially working out in the bush and trying to find out wtf is going on!
