Ford 601 select o speed help!

I have acquired a ford 601 select o speed I finally got it running but I cannot get it to move. When I ease off the "inching" pedal it sounds as if the tractor is loading up but doesn't move also power lift doesn't work. Any help would be greatly appreciated
 
Can the tractor be rolled when the engine is not running? If so, check the traction disconnect. It's on the left side near your left heel when you're sitting on the tractor. It disengages the output of the transmission from the differential to allow the tractor to be moved when it's not running, as the transmission locks itself in Park whenever the engine is not running.

I know when I got it we had trouble getting it on the trailer (not rolling) once I started piecing in back together I could get it to roll in neutral, it was in pieces when I got it from a friend of ours
 

Need more info. It rolls in N with engine running = normal

It rolls in N engine off = Traction disconnect disconnected as Sean said or something abnormal in drive train somewhere behind the flywheel.

So which of those two is it?

Also explain more about what is meant by "tractor was in pieces when we got it". Was the transmission in pieces?
 
it rolls in n while engine off. The hood trans plate shift cable pto cable were all off, the previous owner got it running drove it around a little and let it sit up for a few years and lost interest in it
 

Should not roll in any ratio sans running engine. Go back to traction disconnect first. Make sure you're coupled up there, then get back to us.
 
ok I've been tinkering on it the traction disconnect hasn't been tampered with, the hydraulic pump won't stay prime, it does have some water in the hydraulic oil due to the man having the plate off, ( I know I have to change it) would that make the oil to thin to pump I wanted to make sure I could make it run before changing the fluids, working on a budget
 

What position was the TD in before "it hasn't been tampered with"? I'd want to "tamper" with it enough to find out whether it's engaged or not, anyhow. If worse comes to worst, take the inspection plate off and look to see if the TD is engaged to the rear axle pinion shaft. If the TD is connected and the tractor rolls with engine shut off, you've likely got worse problems than are economically feasible to deal with given other unknowns.

As to your hydraulics, if it's set for awhile with water in it, it's anybody's guess what valves are hung and/or what shape the pump is in.

No, other side (left) by your left heel as you sit on the tractor. Round plate with a dipstick and a funny looking stamped lever next to it. Ain't rocket science, is it engaged or disengaged? if disengaged, tractor is free to roll around. If engaged, tractor has to be running to put it in neutral and move.

Looks like the top cover has been left off and tractor parked outside. Does not bode well. . . . . .
 

Correction: no sign top cover has been left off in picture, but water in transmission isn't good news. I think you need a manual.
 

Allenstone, in order to get help you need to answer the questions asked of you as opposed to what your conclusion is based on who knows what. It is very unusual to find an old tractor that has been sitting that has no water in the housings. It does not indicate any leak.
 
excuse me for being blunt I'm thirty I know nothing about these old tractors I'm trying to learn my grandfather is 86 he doesn't know much about the 601 trans anything else he knows plus his health won't let him help me much that's why I'm looking for yalls help and I appreciate the help y'all are giving me, I'd just confused myself I dunno why I was thinking right side. Yes the tractor had been outdoors uncovered for about 4yrs wasn't taking care of
 
the plate that the shift cable and pto cable run through was not bolted to the trans I'm assuming after 4yrs of being rained on that's how water got in trans in my mind I'm thinking the watered down hydraulic oil isn't thick enough to keep the hydraulic pump prime seeing how the trans and power lift work off the pump,or am I completely wrong? It tried to prime for a minute today the power lift started raising then lost prime and quit
 
as far as the td can anyone tell me what to look for if its engaged or disengaged on the right side by the dipstick I got that now! Thanks everyone for your help

The S-O-S transmission has its own pump and hydraulic system that is completely independent of the 3 point lift system. The external pump on the right side of the engine is only for the 3 point lift hydraulics plus any remote valves it might have.

It is on the left side of the tractor as you are sitting on the seat. On the 1965 and newer thousand series it was on the right side. I can't find any pictures on the internet of what it looks like other than the parts diagrams and those aren't very good. I know there's good pictures out there but I just can't find them. Hopefully someone else will post a link to them. If you have an owner's manual it should be in there. If you don't have one, get one. Likewise with a service manual.


so if the td is disengaged would it sound like the engine is loading up like it wants to move?

With the traction disconnect in the disconnected position, when you shift it into a gear other than Park or Neutral and let the inching pedal out, the engine would still be doing the work of turning all of the shafts and planetary gears in the transmission that it would be turning if it were driving the tractor forward or rearward, so you would hear a little bit of a load on the engine, but nowhere near as much as when it was engaged and it was actually moving the tractor.
 
ok thanks I'm going to check out the td and start changing and flushing the hydraulic oil today and my grandfather told me he has a service manual somewhere so that will be a huge help
 
For the service manual, you need to know which version of S-O-S transmission it has. The original S-O-S on the 601 series had an over running clutch (ORC) which would allow the tractor to freewheel going down hill in certain gears. Later, when the 4 cylinder thousand series came out in'63 they changed to a Direct Drive Clutch (DDC) and then a large number, but not all, of the earlier tractors were retrofitted with the DDC transmissions. If it still has the earlier ORC transmission, everything in the regular service manual for 1955-1964 tractors will be correct. If it has the later DDC transmission then you need the Service manual Supplement for the 4 cylinder 2000 & 4000 Select-O-Speed transmission.
 
Easiest way to post pictures here is to post them someplace else, like photobucket or a similar site that gives you a certain amount of free space to post pictures, and then just paste the URL to the picture on the other site in between the IMG and /IMG tags.
 

That's it. The paint on the little strap would tell me that the eccentric is in the engaged position. I'd want to take that round cover off (you may lose fluid from the hydraulic section, but it sounds like you need to lose it anyway) and get a good look at the TD coupler itself. Visually confirm whether it is in the engaged (transmission tailshaft to pinion shaft) position. It is possible for the eccentric to have been rotated too far and become disconnected from the TDC.
