LA350 FEL will not raise

[Riverboy]

I think that this is a not unusual problem. The loader was working fine and then in the colder weather it would not raise until the tractor had run for a bit and warmed up. Then it worked fine. Now it has stopped working. Only the raise is not working. All other functions work. Bucket curl and down. I tried switching the two lines on the control for the raise/lower functions and it worked. When I inputted to raise the bucket the bucket went down and would lift the front of the tractor. When I inputted to lower the bucket the bucket went up as in normal operation. When I switched the two lines back (quick connectors) I was back to square 1. All other functions worked but the raise did not. Any suggestions greatfully appreciated. The tractor is a B2150 with LA350 FEL. Thanks.

Replacing a quick connect or two might fix it. These are known to fail internally restricting or blocking flow.

Thanks Dave. I'll check the quick connectors. As an update, switching the lines only worked for a bit. One swath up the driveway plowing snow and when I went to use the FEL no lift. All other functions working. Switched the lines back to there correct connection and same thing..no lift.

Yep change both sides (pair) on both hydraulic lines.
