[Farmall] A Few Questions

I found that the previous owner had trouble with the "Clutch return spring"
not bringing the pedal up.  He adjusted those two nuts to allow the clutch
springs to hold the pedal up.  I'm going to go in town for a new spring, and
adjust the pedal accordingly.

Thanks for the tips!
