Ford 4100?

I have just purchased a 4100 ford. I have done some research and found that these tractors were made between 75-81. My question is what can I compare this tractor to. What is this tractor to a 4000? I was thinking it may of replaced the 4000 but wouldn't that be a 4600?

we had a few 4100 in at the dealership I worked at in the late 70's, I knew something was different about them,, I looked at my data book it says the 4100 has a 183 cube engine and the 4600 has a 201 cube engine,,
cnt

The 4100 has about 5 less hp than a 4000. The grill, and possibly some other parts will look a little different on the 4100 compared to the 4000. Some of the internal mechanical parts also maybe slightly upgraded. It should pretty much do the same jobs the 4000 did.

The 4600 replaced the 4000 beginning in
1976. The 3600 replaced the 3000 at the same
time.
Except for upgraded hydraulics and electrics
they were identical to their older sisters.

The 4000 and 4600 SUs (special or super
utility) were a 4000/4600 engine and chassis
with the lighter 3000/3600 wishbone style
front end and steering.

Think of yours as a 4600 SU with a smaller
engine.

It is a great small tractor. Maybe 5 more
ponies than a 3600 but with the excellent
independent PTO, much heavier, double
reduction rear axle and vastly superior wet
brakes of a 4600.

The light front end and short wheelbase
makes it very nimble for plowing, discing,
mowing, raking, etc but not well suited for
loader work.

Ford played around quite a bit with those 3
cylinder engines. They used two different
bores - 4.2 and 4.4".
And they used three different crankshafts -
3.8, 4.2 and 4.4" stroke.
With those combinations they built 158, 175,
183, 192 and 201 cubic inch engines - both
gas and diesel.
Your 183 was the least used combo with 4.2
bore and 4.4" stroke.
The external dimensions on all of them were
identical and one will easily slip into the
place of another.

I have one. Ultra Dog summed it up. They
are a great small tractor. That 183 can
really load up and work. Has lots of torque,
very nimble. Love mine, does everything a
3600 did, better. A little tractor that
thinks it's big. Front end not for loader
work.

I know my 65 and 68 tractors were 4100 and they had the 38" rear wheels while the SU4000 was 28" rear wheels and the 4200 was the row crop version, possibly with a wide front end. They were all in the 4000 series. The 65 had the 201 engine and the 68 had the 199 engine and both were gas but from the numbers on then I think the 65 had come from the factory as a diesel. The 4100 was what would be called a high utility while the su was a low utility. Friend still has a 4200. The 65 has the 201 engine and a steel grill while the 68 had the 199 engine and plastic grill that they switched to in mid 68. I have no idea where you found a 4100 was made between 75 to 81 as the 4100 (sub series of 4000) was first made as a 65 model. And the parts book has these dates in it.

The 4100 was about halfway between a 3600 and a 4600. It had the 3600 front end , a 183 cu in engine, and the 4600 rear end and IPTO.

There must have been two different tractors made over the years that carried the 4100 model number as what all you are saying is not according to the facts that I do know about a 4100 as I have had 2 of them and they are nothing like everybody else is saying. And I have looked at a lot like mine over the years on dealers lots. The 4100 is a subseries of the 4000 that was replaced with the 4600 as far as I know. When it got to that time frame Ford go to where they were hardly any sold in my area so never saw any 4600.

Tractor Data does list the 4100 as a 75-81 model with 183 engine, something I didn't know.

My 4000 series parts book lists a 4100 in the 4000 series that appears to be much like the standard model, both 4000's I had came with 16.9-30 rear tires, my 4000SU came with 14.9-28's.

Thanks for conforming for me to others that I was not crazy on the model numbers. Yours with the 30" tires would have been the 4100 as well unless it was the row crop with the flat platform and I don't know if they put the 30" tires on them as they were considered too wide for row crop work, that is why just about all the 4100 model around me had the 12-13.6 X 38" tires. I also had a 5000-5100 gas early 68 model.

Standard model, I'd like to have a wide front 4200 diesel to complete my collection, but it's not a tractor I really need for my farm work.
I've had my 4000 for over 25 years and it's always been my main go to tractor.
4000SU works great in the poultry barns decrusting and leveling floor bedding, also use it for tilling gardens, tedding and raking hay.
4500 industrial hasn't been used much, never had the hoe and loader is all busted up. Presently adding three point lift, lower draw bar and converting it to a much lighter Farm Hand loader for moving and feeding round bales of hay, also adding a Sims all weather cab.
