Sticking clutch on Satoh Mitsubishi

[Mtjohnso]

Have a Satoh Buck that recently started having stuck clutch issues.
If it sits for more than 3 or 4 days without being driven the clutch will stick I will then have to start it in gear and drive around with clutch depressed until it comes loose.
So what causes this? Moisture? Rust? Leaking oil?
What have you experienced and how did you fix it?

Don't know what's causing it, but the fix is easy- tie the clutch pedal down when you finish using it. Clutch disk must be getting moisture somehow.

My sister-in-law bought a new Ferguson compact tractor a couple years ago.

It came from the factory with a hook to lock the clutch down when parked. Guess they were anticipating the problem.

She didn't know it was there, and never uses it, but has had no problem, yet.
