4310 vs. 3320

laurenzo · Apr 10, 2005

First, my purchasing interest is with the JD 4310. However, while shopping for a 4310 the salesman showed me the new 3320. When I asked him what the differences were, he was sort of at a loss for words. The only thing he could come up with were better control layout or ergonomics and a more pleasing appearing, one-piece, hood - that was about it. The 3320 that was on his lot had an eHydro; he did mention that the 3320 would offer a "mechanical" power reverser, in place of the ePowerReverser. The base price of the 3320 was significantly greater - like three grand?

From what I've read from this forum, it seems that the 4310 is well respected. Questions: First, why would JD replace the 4310 at all? Two, are there any other significant differences that any of you know of that the salesman omitted. I know, from the JD website, that the final output is via. planetary drive. That's fine, but not significant to me. Three, does the discontinuation of the ePowerReverser indicate a problem with same? This is important to me since this is my current transmission choice - I'm going to take delivery on the 4310 next Friday, so any feedback would be appreciated.

Hmmm... I'm getting a 4310 this week as well!

From what I can see, EPA emissions standards, sloping hood, maybe some cool electronics, updated comfort and convenience...

Not enough to get me interested in forgoing the deal I'm getting on my 4310.

I'm early on in this process but it looks like I'll be choosing between the same tractors. Besides the ergonomics/aesthetics you mentioned the only differences seem to be people alluding to an improved version of the ehydro, and an increase in torque (although I just read that a few minutes ago and haven't verified it).

I'm interested to see where this goes.

Maybe I am subconsciously trying to reinforce my decision, but I drove both the 3520 and 4410 and decided to get the older model. I did not like the more sloping hood or the new dashboard. I also did not like the price tag or the HST vs. ePR. No regrets, and after a couple of weeks of living with my 4410, I took another look at the 3520 when I was at my dealer for another reason. Don't choose the 3x20 just because it is the newest. Try them both and buy the one you like the best and the one you can get the best deal on.

Larry,

The 3320 is a nicer machine than is the 4310, BUT it is not 3000 K nicer. The performance of those two machines would be similar. The 3320 has similar torque figures to the 4410, but that even is a small improvement over the 4310. I do not believe the 3320 tractor to be worth the extra money, unless you happen to like the styling. I went with the new 3720 to replace my almost new 4310 and am very happy, but I am happy with the extra power, not necessarily with just the new model.

The 3320 has a larger engine.
It's a 1.6 vs a 1.5 in the 4310. The ehydro is also suppose to be improved by the addition of a second pump.

Although I have a 3520 coming next week, my current 4300 has been an awesome tractor.

Three grrrr?
I think I would have him sharpen his pencil by another thousand, and then I might go for the new 3320.

Hello Larry and welcome to TBN. I actually know where Gause is and have been there. I have a 4310 for over 2 years now and I love it. However, if I was buying new today, I would look long and hard at the 3720 due to the much greater HP and torque provided by the turbo.

What were you priced on the 4310? Be specific about tranny and FEL and such. I can tell you that a 3720 with FEL and Ehydro will run you a bit over 22K. But it has 40% more Hp than the 4310 and is the same size physically. (I like the size)

( First, why would JD replace the 4310 at all? )
For the same reason Ford replaced the 9N with the 2N over sixty years ago. It's easier to raise the price with a new model. That's the MAIN reason, better margin.
( that the final output is via. planetary drive. )
Planetary drive is a "big" tractor feature, it's stronger than the spur drive in the 4000TEN Series and with the introduction of the 3720 JD was concerned about durability. For 97% of the customers spur drive would have sufficed in the new series. JD didn't want to take chances and it was cheaper to use it across the whole 3X20 line.
As far as dropping the EpowrReverser in favor of mechanical, it's another cost issue. The mechanical is cheaper and the ePowrReverser never took off like it was allocated for. Like the chairman on General Motors says, "Don't tie up resources on products with negative momentum".
Bottom line, the new TWENTY Series is better. But is it $3k better? Not to me. Providing I didn't need the extra power of the 3720, I would snap up a new 4310/4410 over the new 3 Series just because of the cost savings.

I received quotes on a 4310 w/ PowerReverser which was on the lot and a 3320 eHydro to order:

4310 ePowerReverser -- $14900
3320 eHydro -- $16300

The 3320 + eHydro for $1400 more was definitely worth the upgrade. Then I had to look at the 3520... and that's what's on the way. /forums/images/graemlins/wink.gif

Kyle in Tex,

Check out my earlier post "4310" for the details and pricing I got - thanks for your input!

Just for information purposes, the JD 4510, 4610 and 4710 tractors have the planetary drive.

The other feature I think was LONG overdue is the new 13.5 gallon fuel tank. For those of us who need to drive to a gas station, this will be very welcome.

KennedyDiesel · Apr 12, 2005

Just FYI, I had low fuel warning come on at about the red on the gauge. I filled it and added 8.5 gallons if memory serves. I wrote down the hours this time 16.2 as I did not note this at the dealer when I took delivery, nor did I verify how full the tank was, only that the gauge read full and the dealer said he filled it.

KennedyDiesel · Apr 12, 2005

I understand the final drive topbe planetary on the large frame and spur gear on the mid frame. The only spec change that I see is the small frame 400-10's list spur gear and the 3000-20's list helical which may or may not indicate a change in the cut of the gear. The earlier ones may well have been helical cut also...

beenthere · Apr 12, 2005

Do you have a link to the website where the final drive is planetary?

I read that the "Rear final drive is spur gear". That is in the manual for the 3520 specifications.

I'm real curious now.

beenthere · Apr 12, 2005

Addition of a second pump?

The 4000's always have had two pumps. Have they added a third? Or just a bigger pump to handle the ehydro?

I'm confused by the 'second pump' comment. Can you help me out?

beenthere · Apr 12, 2005

You indicate the 3x20 series has planetary final drive, and the specs in the 3x20 manual says "Rear final drive spur gear". Seems to be some confusion, and I'd like to discover which is which.
Thanks in advance, if you can help. /forums/images/graemlins/wink.gif

laurenzo · Apr 12, 2005

I'm sorry for the confusion. In my original post regarding the 3320, I erroneously stated that the final drive was "planetary," when in fact (according to the specs from the website) the final output is via helical gearing.

The power steering and implement pump no longer share the same pump. They added a second to split the tasks.
Truthfully, I never experienced a problem with my 4300. /forums/images/graemlins/confused.gif

George,

( The power steering and implement pump no longer share the same pump. )

My 4300 has two pumps, one for the hydraulics and one for the power steering. The pumps are bolted together into one unit (on the left side of the engine in the front) and share the same drive mechanism. It looks like a single pump but it is actually two pumps driven in tandem.

I suspect that your 4300 is set up the same way.
