Lift and tilt hydraulics mixed?

[Hman0217]

Hello I have a 2021 l3901 with just under 200 hours on it. I was operating yesterday when, suddenly, pulling the stick down towards me ceased to lift the bucket, save a very slow creep up (maybe two to three minutes for a full lift)

Suspecting power loss, I tested the backhoe and the loader tilt functions and found no issues.

Accidentally, I found that I could easily lift the bucket by moving the stick towards the tilt side (right instead of down)!

In other words, if we think of it as north(lift up), south (lower down), west (tilt back), east (tilt down), I could simultaneously lift and tilt down by moving the joystick southeast. I managed to keep working by alternating between alternating doing this in small steps and moving the joystick west to not tilt the bucket too far forward and spill my contents.

Has anybody seen this phenomenon and know a cause or fix?

This behavior has been seen before and is symptomatic of something blocking the power beyond circuit.

My initial suspicion is something backhoe related. Disconnect the backhoe supply and return hoses and loop them together to see if that gets the loader working again.

I would also suggest you refrain from using the machine until you find and fix the problem. You are likely running the hydraulucs against the system relief and stressing the pump

Thank you! I didn't even have to go that far. I went to do so and found the line to the backhoe had it's fitting stuck in an intermediate position (partially retracted) finagled it back into place and were good to go.

Appreciate your help
