Loader not going up

[snailcrusher]

Hi,
I have Kubota B2650 Tractor with a LA534 Front Loader.
It has less than 300 hours on it.
The Loader was having a lot of difficulty going up. Sometimes, instead of going up the Bucket would tilt. When I tried to lower the Loader, it would jump into float mode and drop.
The next day I tested it again. It worked better but went up very slowly.
On the second day everything worked fine.
I checked Hydraulic fluid and it is normal.
About 6 weeks ago I had a similar problem. Took it to the shop. But, then it was working fine and they couldn't find anything wrong.
Please help

Simple things first. Try disconnecting and reconnecting the loader quick couplers, sometimes they don't seat right and sometimes they just have to be replaced if for some reason they are restricting flow.

Anything else hydraulic on your tractor..... rear remotes, top and tilt, third function.
