I am going to look at a 600 tomorrow. Don't know a lot about Fords,grew up on JD . I cannot find a lot of info on Tractor Data on the 600. This one has the blue chassis,. A couple I saw for sale were red chassis. Which is correct? What years did they span, hp rating, Ect. Anything special to look for to evaluate this model? Any help appreciated. Thanks
 
The 600 is the series of the tractor not the model. The transmission pretty much says what the model is. the 620, 630 and 640 have 4 speed transmission. The 650 has a 5 speed non-live PTO and the 660 has a 2 stage clutch and 5 speed with live PTO. The 600 series was made from 1955 to 1957 and in 58 they changed them some and wet to the 601 series. It should not be painted blue that was a thing done to try to pass them off as a newer machine then they where
 
That style of tractor was built from 1953-1964 The NAA(grey tin, red chassis)built in 1953 & 54.The 600 series was built from 1955-57,grey tin red chassis. The 601 series went from 1958 to 1962. All red except grille, fenders a wheels. The 2000 series built 1963 &64 are all blue .except wheels. All the above models should have the model and SN just above and behind thee starter on the transmission housing
 
Thanks for the info-- Any obvious weak points to look for in these models? Any areas prone to be problems?
 
First ones, 53-56, came with a vane hyd pump(rectangular in shape) not so good. Most have been replaced with the later piston pump, the same is used on the later tractors. Almost bullet proof.
If a loader was used, check spindle thrust bearings and center axle pivot bushing. These tractors were not overdone if a loader was used. Just remember these tractors 50+ years old, but are usually very dependable tractors.
 
Help--Just talked to the owner about visiting tomorrow. he said the clutch is stuck! But, he would FREE IT UP. If it is stuck how can it be freed up without splitting the Tractor to get to the clutch? Said it runs good and he has been driving it around. How can you drive it with the clutch stuck, Start and stop in gear! Starting to sound like I should pass on this one?? Any help appreciated. Thanks
 
Very common problem on most any tractor. To free it up the guy will m9ost likely drive it around in a high gear holding the clutch pedal down and hit the brakes off and on. As for how he does it yep he starts it in gear which again is not all that hard to do. One common thing to help keep a clutch from sticking like that is to block the pedal down when not being used. I have an 8N that has a cement block on the pedal right now because of that problem
 
Not that uncommon for these clutches to stick to the flywheel.
We usually block them down when not in use.
They get hot while in use, then draw moisture and rust a bit when sitting.
They can be unstuck by driving them around with the clutch held down
sometimes, or by pulling the starter and spraying brake cleaner on them.
Once in a while just by blocking the clutch down a couple days and rocking
it with the tractor in gear.
I wouldn't consider it a deal breaker if the price is right.
 
clutch can be easy to unstick, no split many times.

600/601/2000 4 cyl all basicaly same.

make sure it is a pre 64 / 4 cyl.. then post the # from the bellhousing aft of the starter.. hand stamped.. not cast in.

pics will help
 
Thanks for all the info--- This is new for me as my old 2-cyl. JDs do not have this problem. I will let you know what happens. Thanks
 
Well, I looked at the Ford today. Serial # 14401--. Looked like it must have been a Road Dept. tractor as the yellow paint was showing thru the blistered blue. Started and ran. Could not drive it as the owner was not there. Extra straps on the sides of the 3 pt. Wired to the 3 pt. Don't know how bad the clutch is stuck. Think I will pass. Thanks much for all the info. These discussion forums are really helpful.
