Which Offset Tractor is Best? A - Super A - 100 - 130 - 140

Hi All--

The (sometimes conflicting) information that I have been able to glean from various websites indicates that International Harvester made incremental improvements in its Farmall A - Super A - 100 - 130 - 140 continuum. I would like to buy an offset tractor that has some of the best features, and am hoping for some help in determining which one that might be. My questions are as follows:

1. When did the 12 volt electrical system become available?

2. Were remote hydraulics ever available? If so, when?

3. Was a (factory installed) 3 point hitch ever available? If so, which model(s)?

4. Was a live PTO ever available? If so, when?

5. Do the Industrial versions have any advantages over the Agricultural versions?

6. What other features would make a difference in what model to buy?

7. I like the looks of the A and Super A. Would it be possible to put an A hood and grill on one of the later models? The fuel tank looks similar, so I am hoping that swapping hood and grill should be an easy operation.

Thank you very much for any information that you can provide.

1. Probably in the late 50's early-mid 60's. 12V is not necessary on that small engine.
2. I believe from the start of SA production.
3. No
4. No
5. Heavy duty front axle, foot accelerator, no real advantages unless you beat it to death.
6. HP increased slightly with each model, PTO HP from about 18 for the A to 23 for the 140. Overhaul kits are available to increase cu in from 113 to 123 cid in the A and early Super A to 132 in the late Super A-up.
7. Don't know, if you don't like the 140 styling buy an earlier model.

The main difference is that the A did not have hydraulics. 100-up was available with single point fast hitch. The condition of the tractor means more than the slight differences.
 
If I am understanding correctly, "remote hydraulics", which are connections and a valve for extra hydraulic implements, were never a factory option to the best of my knowledge for this series of tractors.

The Farmall 140 (1966-1979) is my favorite because of its slightly longer hood/nose, easier steering, deluxe seat option, lighting options, key start, 12 volt alternator, and fast hitch option. I also like them because of the sheetmetal and paint scheme.

The other offset tractors can be fitted with any of these options, but the 140 came with them from the factory. I would rule out the "A" because it does not have hydraulics, and isn't compatible as well with equipment as the others are.

The 140 will be the most expensive of the 4 models, however is still the newest. We've got 4 140's (1 older style and 3 later styles) and they are great tractors.
 
I'll post pictures of my 140's soon if you guys would like to see them. I can also post some of the super a's and 100 we've got.

Yall just let me know, and I'll get 'em.
 
Remote hydraulics, the lines, lever and cylinder, etc are in the parts book -- check the parts section of www.caseih.com. Whether or not they were an option from day one or were added later I don't know. I have learned from experience that it is not good to make a statement without checking first.
 
Thank you for the quick responses, and for the useful information.

Relative to Question 2, Remote hydraulics: Were remote hydraulic hose hook-ups available? I know the Super A (and onward) had Touch Control, which I assume was for operating a dedicated single-acting cylinder used for raising its own attachments (with gravity doing the lowering). But I want to be able to operate a trailed implement that has its own double-acting hydraulic cylinder. Would this be a matter of simply matching the style of quick disconnects, or would I have to add some plumbing to the tractor, or go all the way and add a PTO hydraulic pump and reservoir?

Thanks again

You would have to go into the system to add a two-way control valve and possibility a resivour as the fluid capacity isnt too great. Your best and quickest would be to add a Char-Lynn Power pac unit and run it off the pto. The unit has single and two-way along with the pump and res all in one unit. Good pressure and flow for anything you mite need to lift. Great units ytouble free iv used them for yrs on my loader,splitter,rear bladeand small wheel disc on my Bs.Very hand units.
 
There is always a new hydraulic bypass block for the SA and later on eBay. Around $40. You will also have to buy a valve and hoses. If I recall, the valve will have to be closed center but the bypass block instructions will have a plumbing diagram.

IH used to sell them as well. I put a similar IH block on a Cub to run a double-acting dump cart way back in the '70s.
 
The original setup had a 2 way cylinder, I believe. But the original parts are going to be hard to find. You can use a diversion fitting or valve that fits under the original tubes on the reservoir and run to a spool valve and on to the rear. These valves are readily available from several sources. The reservoir will have enough capacity for small implements, however capacity can be a problem for a large implement such as a loader as Gene says. I would think it would work on a small tandem disk, etc. You can use a double acting or single acting cylinder.
 
Double acting cylinders require very little extra reservoir capacity. Maybe 6 ounces max.

The bypass block installation is a five minute job. A NASCAR pit crew could do it faster than changing four tires.

Could he install a system like the one found on a Farmall 200 with a fast hitch??? Would the special manifold and valve work on the Super A?
 
Yes, the bypass block will work on a SA. Don't know nuttin bout 200's. All I can say is that the fast hitch lines can be interrupted with with a double selector valve to provide another circuit when that circuit is selected via its integral knob. Double selector valves are kinda expensive. They aren't the same as a regular lever valve.
 
As to which tractor is best, except for the "A" not having hydraulics, all of the others are equal in my opinion with only very minor differences. Six volt vs twelve volt should not make any difference, None had factory three point hitch. None had live pto. All have same hydraulic system. The industrial models do have a foot accelerator and a heavier front axle. Looks are a mater of choice, but I personally would not go swapping hoods and grills.

Wrong. Check the IH accessory manuals.
Other than that, I totally agree with your other observations regarding the various models.

MY vote is for the 140 with the one point hitch , one point equipment can be found . I love it ---I can change implements with just a hook ( Lift locking pawl on fast hitch) and never leave the tractor seat . Has more power then other models . I am the proud owner of a 1959 140 and a 1953 cub
Yes and I spent about 14 years cultivation tobacco on the seat of a 140 , best at doing close work IMHO----Started on a cub at age 6 with 4x4 taped to petals --cultivating corn -----LOL
 
I know I am jumping in on an older thread but I had to respond. I just picked up a 74" 140 tonight. It"s my first red tractor I think I will love it. Came with a little 5 ft. angle snow blade. I would appreciate any photos. I am thinking about a rack on the back to haul the deer out. Did anyone ever fab one? I was thinking about a 3"x4" hanging on top of the draw bar somehow.
 
Thanks to all who weighed in with helpful thoughts and info. I'll check this thread again periodically, so if anyone else would like to add their insights, please do so! Thanks again.

I don't know what your planning on pulling with it, but if you went to a little bigger tractor like a Super C, 200, or 240, you could have a lot more options and more power. My dad's 240 has a nice 3pt. setup and I'm sure I could run remotes if I wanted. The A's are nice little tractors but they aren't much when you want to work them.
