Kubota B2620 w/LA364 Loader - Control Lever Sticking ?

[Monzo]

First off, I am new to this site (my 1st post) & I am "old" (84) so I apologize in advance if I am not being clear about something, or goofed something up in this post.
I have a Kubota B2620 tractor & I am having an issue with the control lever on the LA364 loader sometimes when want to tilt the bucket up/down, or raise/lower the bucket the Control lever seems to stick, however if I move it a little left or right it then seems to work ok....is there something that is worn somewhere that needs to be replaced ?

Thank you in advance for your assistance,

Sounds most likely to be sticky/dirty linkages. If the loader stick is directly connected there’s probably a cover over the valve. Take it off or at least get it loose so you can slide it up the stick to get to the valve and all the joints where the stick attaches. Clean and lubricate the linkages with a light lube.

If it’s the type where the stick is on the fender remote from the valve, same principle. Clean and lubricate the linkages, there will just be more of them due to the remote location of the stick v the valve.

While you’re doing all that, also check the linkages for excessive play/wear.

While it’s possible there’s an actual problem with the valve, the issue you describe is more commonly a sticky/dirty linkage issue.
