Thoughts on IH 684

I'm considering buying a 1983 IH 684 with a 2255 loader. Is there anything in particular I should know about this tractor or loader model? Opinions, flaws, parts availability/expense, etc?

The steering seemed slightly less responsive at lower RPM, fine at higher RPM. The seller said something along the lines of "that's how IH tractors are". Is that nonsense?
The tractor in question
 
I think it is pro ed on the high side , loader is reputable and the tractor is of a good family, side or fender shift can get sloppy and cause pure he!! ,but all on all good tractor.
 
Old hydraulic oil & a filter that hasn't been changed in years is probably more the issue than "thats how IH tractors are" What a line of bs.
 

The steering issue could be a sticking flow divider, easy fix.

Those are pretty good tractors and the loader is good as long as it's not treated like a bulldozer. Best feature is real easy on and off if you don't always need the loader for other tasks.
 
Just sold my 784 which Ive had for 15 years, only ever used it for lifting and towing thing around my site. Good starter, light steering but couldnt say it was a likable machine. Unless you put lots of weight on the back I found it pretty useless, I think people like them but not a favourite of mine.

So, just to clarify, you found the backend to be too light? Was that with the loader on, or off, or both? Was the the primary reason you found it unlikeable, or were there other aspects that you found irritating?
 
Yeah, good advice. Also good advice about the complete filter/fluid change.

The quick on/off loader was one of the reasons I was attracted to it, but I wasn't sure if that would be something I would use a lot or not. If the rear end is somewhat light as someone else was indicating, that actually might be very useful.

Re "treated like a bulldozer": Do you mean specifically pushing stuff, or just treating it like it's indestructible?
 
I'm confused. Is this in reply to the comment about sloppy shifting? What do you mean by shift pattern? What changed in the 1983 version?
 
Sorry for my ignorance...but when you say "side" or "fender" shift, are you referring to the 1,2,3,4, and high/low gear selectors? Are you talking about a transmission problem, or something with the shift levers themselves?
 

1982 and newer 84 series had H shift pattern, not lightning bolt pattern, hence why it's not a 1983.

The transmission is the same (8F/4R unless optional TA etc)

Shift linkage can get some wear in it, but it's all external and easy to see any issues (easy on open station)

2250 loader solid, made them for years, 2wd won't tear one up.

Any 2wd is too light on back with loader, need counter weight or fluid. I am guessing the 684 might already have fluid in it.

Ran a 2wd loader here for years, fluid + chains + counter weight you could do way more than you should.

Treating like it's indestructible.

Push but don't ram.
 
Ah OK, got it now. That's good to know. I'll have to see if I can find the serial number on it.

If there was fluid in the wheels would I either hear it or feel some "slosh" on a hard stop?
 
It is definitely not a 1983. The thousands digit on the tach is askew; it looks like a 2250 loader, not a 2255. You better check it out carefully. Too many errors in the listing.

If they are full you shouldn't

Sometimes you can feel by knocking on the side of the tire.

Sure fire way, and only if the valve stems are good...check the rear tire pressure...(with a fluid gauge or some cheap one you can toss)
 
I am ivor from uk and 40 years ago I worked at local IH main dealer
does handbrake work??
do footbrakes work?
does PTO work
with big front bucket there will be wear in steering linkage and front axle
also check for coolant in oil
 
You can check the presence ov fluid in the tires with a stud finder (Zircon is one make) that senses density, Not magnetic. Jim
 
With the loader on but even for hauling it lacks grip.Easy to drive though onces to crawl into that cab. Sorry Im just dont warm to them. I like my International 634 much better, now thats got wheel grip, definately punches above its weight.
 
A friend of mine has one and uses it a lot. Has a bunch of hours on it. He services it like the book calls for and never been apart for any thing. Buy it if you haven't ...........Kenny
