3400 vs 3600 general information about 3400's

So, while my 850 is hanging in there, but just needs quite a bit of work, steering, front axle pivot pin, transmission and now a throwout bearing. I've got too much work to do and really need to make a move to something like a 3400, or so I think, given I've seen several around reasonably priced in seemingly decent condition, price is dictating much of this, as well as being out of work, I'd like to go newer if I could, but I think one of these would be a noticeable improvement over an 850 with a wagner loader. Sure I'd like a shuttle shift like later models, for the loader work, then again, I don't use a tractor that much where I'd be handling materials all day, so I could live without it, and it may be better for drawbar work anyway.

We have a 1980 3600 diesel at the other place, it even had a loader at one time. I am familiar with that one and general purpose models, its all I or we have ever owned. Ours has the 8 speed with 2 speed reverse, I know the 3400 was offered with at least 3 transmission options, I know we sold a few new at our dealership way back when, can't recall the details, but assume even with the 6 spd, could you run a tiller or snowblower with it ?

My question is, how would a '73 3400 diesel compare to a '80 3600 diesel, generally speaking, comparing specs of each and what limitations would the industrial model have for the work described, mold board plow, blower, tiller etc. ?

Specifically, what about using ag implements such as a moldboard plow, would a ford 101 2-14 or 2-16 plow align well enough to use for plowing, I have 2 nice size plots to work, and food plots, one in a field that is over 5 acres.

Seems the front axle setting on my 850 would not be much different than what is fixed on the 3400.

In simple terms, I've always got loader work to be done, an industrial model would be best, but I would like to be able to use a plow fall and spring, use a disc harrow, and other implements, just wondering where the ag or general purpose model may differ. I'm not really farming, so that may help.

I've seen one with sort of an open cab, a nice one that's built for the tractor, no sides or back, just a windshield, not sure the make, it has pie weights, looks straight. I have not seen it, but would contemplate doing so if I knew it would be a decent choice. I'll be selling something to fund this, want to make sure I spend wisely.

To be short, the 3400 was a 3000 tractor with a heavy front axle. But there are some significant differences. It had 14.9 x 24 rear wheels and 9.5 x 15(?) fronts. The front end loader was powered by a front-mounted pump. Mine happened to come without the 3-point top cover. It did have a PTO drive. It was a handy little diesel. My brother now owns it.
I used a rototiller with my 3000, but it almost went too fast in the slowest gear.
I'm pretty sure the 3400 runs much slower in each gear, so it would be better, I'd think.
I have a 2000 Industrial with the shuttle. It is a set of hydraulically-operated reversing clutches, with a torque converter. Only a 4 speed transmission, though. More complications.
I now use an old, almost-used-up L5450 for most of my work.

As cdmn said, the 3400 was basically the same tractor as the 3000 with the exception of the heavier duty non-adjustable front axle. I would think that the turning radius wouldn't be as tight on the 3400 as it is on the 3000 and 3600, but other than that it should be very similar.

The 3400 was available with a few different transmissions, with the most common being the manual reverser (earliest ones were 4x4, but sometime around '67 or '68 they switched to 6x4), the 4x4 auto reverser that cdmn mentioned (also called the torque converter) and the Select-O-Speed.

The 3400 was available with and without the 3 point lift and the PTO. They should be fine for plowing, disking, tilling, etc. as long as they have the 3 pint and/or PTO if your implements require them.

Generally I would say that a 3400 would be a good choice as long as it has the 3 point and PTO options that you require.

Much appreciated, I think one of these would suffice for what I do, just did not know a heck of a lot about them, ironic, since we sold a few new back in the day.
