What does 3000/4000 Twenty series mean?

elemint · May 6, 2005

I went to look at a JD 3000 and some other models. My question is what the heck is a 3000/4000 20??? Is it the engine size? Why do these tractor makers make things so confusing? There is a 4000 Ten series, a 03 series, a 90 series that means 790 or 990, etc... Even more confusing than the kubot line.

This syestem is designed to simplify things;

3000-20 etrminology refers to 3120, 3320, 3520, and 3720 which are the mid chassis models

Same folows for the 4000-20's

Used to be the large, mid ans small chassis were covered in the 4000-10 series, but now there is a disticntion between chassis.

On the Tractorbynet.com home page, there is an artile by Muhammad covering the release of the 4000-20's...

Thanks for the link. Do you have the 3000/20 series? What do you think about it?

I remember having the same problem. I grew up with A, B, H, G, R, and M as the only models Deere had.
Then came the 40, 50, 60, 70, and 80's. Then came the 420, 520, 620, 720, 820, and then the 430, 435, 530, 630, 730 and the 830. After that, the 2cyl models ceased, and the whole system' blew apart /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

I was lost, really lost until I started looking at the 1070 utility (compact utility I think) and that is when the 4000 series was coming out. I bought the Deere 4300 and all of a sudden the other numbers started making sense (then 4300 became the new 4310 etc).
Now the 20 series came out and the 4320 wasn't much like the 4310, but was a larger frame. The comparable tractors to the 4300 I have, became the new 3000-20 series and have numbers like 3120, 3320, 3520, and 3720 (I think /forums/images/graemlins/grin.gif )

So don't feel alone. It's mind boggling, but probably necessary to keep things somewhat straight within Deere and with the dealers. Maybe what computers are for, to keep it straight. /forums/images/graemlins/tongue.gif

What do I think? I'm going to get me a Deere 3520, if that helps. Same frame size as my 4300, but more HP under the hood and 6 (or 7) years newer.

Thanks this is a good and informative post. I am thinking along the same lines as you are for my 4100. I have a 2001 4100 and I am thinking of getting a newer tractor along with the new property I am looking to purchase - up to 4 acres, probably up to 1.5 acres. I want more horses and a newer tractor, but I kinda want to see what newer models are coming out and what deals i can get in the more tractor competitive market that I am moving into. /forums/images/graemlins/cool.gif
