JD 4020 Industrial

Need some Sherlock Holmes work from you green guys and gals.

A neighbor of ours has a 4020 Industrial. Reportedly this is a very rare piece as only 10 were made and three are known to exist.

Our neighbor recently contacted JD about this. They were very interested and sent a representative out to get casting numbers off the tractor. JD made and sent a new SN tag to be put on the 4020.

Our neighbor and JD want to verify the three-known-to-exist number. So if any of you out there with some information to add, please post it. I offered to help out by posting the inquiry here along with a pic we have of the machine.

That 4020 Industrial is a hoss! Our neighbor call it THE BEAST. Go figure!

The really low production numbers were the gas JD600 (4020 Industrial is the same thing), with only 11 made. Still only 840 diesels made, so not easy to find.

I don't know where that "3 to exsist" came from. No one can say things like that. More rare tractors come out of the woodwork all the time!

If possible, could you send the serial number to me so I can add it to my list of Survivors? Is it a gas, or diesel, etc.

You've got a point. Let's just say that there are 3 of the 4010 Industrials with gasoline engines known to be in the hands of collectors at this time. A more accurate statement.

I hadn't given it a thought--that is, distinguish between a gas or diesel. Frankly, I don't know what it is.

I heard more about this tractor yesterday morning, and the owner wanted to cast a large net for more information about it. I should've followed my first instincts and find out a wee bit more about it along with getting better pictures. In my eagerness to help out, I didn't ferret out enough basic info before hopping on here.

BTW: nice website you've got. I've bookmarked it.

Hmmm...yes, 851 produced sure does blow the quantity of ten number out of the water. It appears that this thing isn't as rare as thought.

I'm getting this information third hand, although it's from a very reliable source. The 851 number makes me wonder why JD made a big deal (so I was told) about coming out to see this tractor and issuing a new data plate. Maybe there was a few of these JD 600s that came off the line without the JD 600 tag and were indeed tagged 4020 Industrials. I have seen this tractor personally only one time and can't recall seeing the model decal (if there are any on it!)

What I originally understood about this tractor was that 8 were made and 4 exist. I was told these figures were corrected to 10 made and 3 exist when our neighbor contacted JD.

Thanks again. I will pursue this some more.
