My new Ford 4000

[Kirk-NJ]

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

 

[kuschneider]

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?

 

[Soundguy]

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?

 

[gemutlich]

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?

the pto is an independent clutch setup. ie.. wet clutch.

there is a torque limiting clutch at the front of the tranny.. but it isn't a clutch the user has access too..

so no.. no 'clutches' for the user. It is a full powershift transmission.

 

[the old grind]

Thanks SG.

Reason I asked is having had motorbike experience like gemultich relates on p.3. I'd think wet 'multi-plates' could stick whether foot or servo operated. Breaking them loose would seem more difficult if there was any fluid coupling in the power path to cushion a servo's typical all or nothing engagement and couldn't be 'forced'.

Anyway, totally stoked on the 'deal' the OP got, and of course on 4000-series Fords. And to me, the older a model is and/or more intermittent its intended tasks the more I'd be OK with gas vs diesel power, esp fearing what could go wrong when reviving from long sits. (fuel quality/contamination, etc) IMO 'carbs' are easier (cheaper) to troubleshoot/replace than injector pumps when power wanes, and food plot work isn't a constant chore for most.

I was talking to a more experience tractor guy, it appears that maybe my expectations for how fast the PTO is supposed to turn were set a little high. We shall see. Tonight I am planning on getting the gas tank my buddy refurbished back on and hooked up, drain enough coolant to replace the upper radiator hose, and roll it out of my garage, and re engage the transmission and see what we have in terms of gears on the SOS. We have only started and run it for a minute at most.

I picked up the brush hog and blade last night. Looking forward to hooking it up and getting a solid understanding of where we sit with the PTO. Things are going pretty well so far though.

I check the fluid through the transmission filler plug. IT was plum full, and pretty darn clear. Is the CORRECT tractor hydraulic fluid supposed to be red, or did they just use some lame ATF? The fluid on the differential dip stick is full and also very clear.

Thanks for the help fellas. She is coming along.

 

[gemutlich]

Clear huh? Did you stick your finger in it and see if it had any oily quality? Typically water will settle beneath oil but who knows... That's why I'm planning on draining and flushing everything in that '641 I just bought - just so I know for sure what I'm starting off with. Peace of mind, plus it could help me identify a potential problem, and help me in the troubleshooting process of elimination yeah?

Keep us posted, and pics are real easy to put up here so keep 'em coming!

Easy now. He knows the difference between oil and water. You two guys should buddy up and share experiences.

 

[kuschneider]

Well after 14 years of teaching chemistry I can confidently say I know the difference between water and oil. When I say clear i mean Transparent, not cloudy nasty dirty burnt up oil. I agree with your decision to drain and refill tranny oil. I see that in my future as well, just verifying the fluid level before we try to get it into gear for the first time this evening.

 

[Soundguy]

Some utf are a clearish amber, some are dyed red or green, etc.

Yep. Ur on track. As identified by Soundguy, wouldn't pay much attention to color. Too many variables. As for water, I search for that discoloration after running the machine. Chocolate milk color.

Change all fluids. But you already know that.

Oh, I'm not doubting anyones' ability to distinguish between oil and water, was just thrown by the choice of the word "clear" - more so because I've had my share of exposure to equipment that being left outside had more than their share of water where water had no business being, lol. Either through weather, condensation from daily exposure to sun and cooling of at night, or even simple tom-foolery. And considering the nature of the problem the OP thought he had, the effects of water in there could explain in part what he thought he had going on.

I'm all for a trip to Missouri, last time I was there was during Army life. Afraid Water Moccasins just don't taste as good as the rabbits we have in Tennessee though so I'll stick a little closer to Home!

Well fellas, here is the video. Both R1 and R2 are good. Made it up to 8th. Gotta little carb adjusting to do, maybe the float? But we are looking good.
