My new Ford 4000

Maybe a later style inching pedal. It's not like a clutch pedal where you are pushing again 2 springs so you will feel little resistance. I'm not sure why the position is so high?

Well,
My buddy is wrapping up the gas tank resto this weekend. Hope to have it running off the normal ignition circuit so I can try and slip it into gear and see what the story is, got my fingers crossed

I have the FO-20 manual. It has a SOS section in it, but I didn't see anything about this switch specifically. Is there another SOS manual supplement I need to track down?

I noticed that the PTO spins anytime the tractor is running. I have read that that isn't uncommon since there isn't a PTO brake, but it shouldn't be under power and if you pressed a 2x4 against it that it'd probably stop spinning. Well I cannot stop it from spinning. It appears to be under power (to some extent), but it isn't spinning full speed. Pulling the PTO cable out or pushing it in right now, seems to have no effect on it.

Also, anyone know of tractor shop/mechanic that services these SOS tractors in Missouri or SW Illinois?

there is an sos supplement...

isn't spinning full speed? pto speed is dependent upon engine speed. it's doesn't spin 540 no matter what... only when the engine is at the correct speed.

 

[kuschneider]

No matter the engine speed or position of the PTO handle the spinning of the PTO shaft is the same. Slow and under power.

 

[Soundguy]

not possible.

pto speed is tied to engine speed. there is no magic gnome in there that turns the pto at the same rpm regardless what speed the engine is. If one existed.. everyone would want one. You could tell the gnome to turn the pto at 540 rpm, and then just idle the tractor around ... that's the definition of magic.

OK. Then my guess is that even though the PTO is spinning with enough "umph" that I can't stop it with a 2x4 it actually isn't under power, and it is just fluid coupling that I have read about causing the shaft to spin. Which would mean my PTO cable is broken or severely out of adjustment.

I'm with Soundguy. Don't think we've got to the bottom of the PTO thing yet.

 

[the old grind]

Is there any mechanical clutch in S-o-S Fords? (none for PTO? ..)

If so, just 'stuck' after sitting for so long?

Thinking out loud talking out of my pooper here, but I wonder what would happen if you tried starting the tractor with the pto connected to a load? Or have you tried that already and I just missed it?

I had an old Triumph motorcycle 30 years or so ago that if I didn't store with the clutch handle pulled in and held open with a shoestring the only way I could get that stack to release was kick it over in gear with the ignition off, front wheel strapped tightly against a tree.

I know little to nothing about these Ford tractors, so like I said I'm talking from a place I have no business talking from anyway but what would happen if you pulled the coil wire and tried to start the tractor while the pto shaft was made so that it couldn't turn? Would the starter have enough torque to overcome this hydraulic coupling you're speaking of and free up the pto shaft?
