Clutch keeps getting stuck on my 8n

[somanytractors]

I've got an 8n that I just got going and the clutch keeps getting stuck. I'm wondering if theres anything I can spray on it to stop it. I'm hoping it will stop on its own but I dont know.
When I got it the clutch was stuck. I split the tractor and got it loose (maybe I should have pulled it and had a look at it but I wasn't expecting it to be a problem). Put the tractor together and finished and it was stuck again. If I start it in 4th with the clutch in it will break loose so it's not sticking bad but it happens every time I park it over night. I'm afraid if I leave it for a month it might really get stuck.
Has anyone ever ran into this and if so how did you stop it?
I'm really hoping there's an easy fix for this. I really dont want to pull this back apart to fix the clutch just because it's sticking.
If anyone has any ideas, I'm all ears.
Any help is greatly appreciated.
Thanks
John

Hate to say it but the splined shaft may be bent from a previous event.

Common problem with the N tractors especially if they are left outside, the cure is to block the clutch pedal down when not in use.
