New 4x20 series v. mid frame 4000\'s

Fellow posters: In an earlier post, I inquired about the new large frame compact John Deere's. I recently bought a 4310 which I really like, except that it lacks some gumption on long climbs and in transport duties. Unfortunatelyfor me , I spend a lot of my tractor time hauling things from one place to another - generally up a down a long gravel road with a 10-12% grade - so this is an important task and I become a little frustrated that my tractor doesn't have a bit more power. With a heavy load, I must run in "a" range or in "b" range with loadmatch engaged, which will slow my ground speed to about 3-4 mph to prevent stalling. Both through advice shared by my fellow posters and by the advice of my dealer, I have run and run my new tractor recently to "break it in." Although it is better after 50 hours of use I do not think it will gain enough grunt make me 100% satisfied with its mid range power. What I would like is better performance in "B" range on hilly terrain. I take many buckets of material up and down these long grades which can be time-consuming with my current machine. I know about the new 3000 series, but they seem to be delayed in their release (this concerns me about a potential manufacturing glitch) and the proposed 3720, with it extra power, may not be released until later in the year. This fact has prompted me to look at the 4120 and 4320 models. I am curious as to whether new owners of these machines feel they offer the power I seek, and whether the Power Tech engines have been reliable. I REALLY do not need a tractor that physical size (or cost) but would consider it if I could achieve a substantial performance upgrade. I purchased my current machine from my old hometown JD dealer, which is two hours away. Our local dealer (who I also know well) has two 4320 tractors to try, but both are 12/12's and I definitely want hydro, so the comparison would not be direct. They also are apparently not getting any hydro's soon, and have no word on the new 3000 series. Overall though, I am quite pleased with my 4310, I just need more beans. Any thoughts? Thanks in advance for the input.

I am waiting for the 'more beans' in the 3000's coming up. I expect more, and expect that Deere will deliver. They know, I am sure, what is needed. Doesn't bother me that they are coming when they are ready and not before. I don't want one pushed out the door too soon. I understand Deere is going to their own diesel (3cyl), rather than the Yanmar, which I expect to be backed up by their long experience in building their own, albeit bigger ones than the Yanmar.
What say those who already have the 4x20's? Are they more torque than the 45-4700 Yanmars?

Hopefully you will get to demo a large frame hydro and can give us some feedback.

My 4300 goes up 15% slope road with full load in the bucket in 'b' range. Not sure why your 4310 doesn't do something similar. Mine won't do it in "C" range though with no load. Other than digging in dirt with the bucket, or tilling, I just rarely get into 'A' range for power needs. But hard to say when not there.

Random thoughts.

The 3000 series isn't delayed. They were always listed as a spring item. We just keep digging up info on them. Trust me, it is hidden.

Like this:
3120 3TNV84......1.5L...33.0Hp....67.8 Ft/Lb@1400rpm...normal
3320 3TNV88......1.6L...37.7Hp....78.9 Ft/Lb@1200rpm...normal
3520 3TNV84T....1.5L...40.1Hp....85.6 Ft/Lb@1400rpm...turbo
3720 3TNV84HT..1.5L...43.7Hp....101 Ft/Lb@1560rpm...intercooled turbo

4210 3TNE82A....1.3L...27.0Hp....52.4 Ft/Lb@2600rpm
4310 3TNE84......1.5L...31.2Hp....57.9 Ft/Lb@2600rpm
4410 3TNE88......1.6L...34.6Hp....64.8 Ft/Lb@2600rpm

You are right that the 3720 is scheduled for later release.

Beenthere, where did you get that Yanmar was being dropped? Deere still shows Yanmar at their site

On the 4000TWENTYs. don't forget that you are moving up in frame size. Just be sure that if you move up that you don't get back in the same spot (underpowered) But they are all the same, as far as parts. It sure seems like a 4120 could be a 4720 if you wanted it to. It might take a year or two for the waranty to run out... But that is hearsay, haven't heard of anyone actually doing it, and I don't blame anyone for getting the "bigger" units

Re: New 4x20 series v. mid frame 4000\'s

We have a 4120 w/12x12 tranny. Haven't done any really heavy work yet...well, maybe I have. Depends on the definition. Yesterday I was taking full scoops of rocks in B range, 3rd gear up and down hills with no problems at all. Had plenty of power it seemed to me. Also, we had a few descent size black locust stumps lying around with dirt still attached to the rootball. I pushed them about 300' over to the burn pile. I didn't feel like hooking up a chain and dragging them, so I put it in 4x4 and lowered the bucket to the base of the stump and off I went /forums/images/graemlins/smile.gif I had the engine set to about 2,000 RPMs for all this work, occasionally stepping on the pedal to increase engine speed.

Re: New 4x20 series v. mid frame 4000\'s

One more random thought. I have heard JD techs say that the engines we have now are no where near the power the older ones had. ( I am not sure now if older meant the 4000s or x55s) The idea I have had is that this is a emissions thing( /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif). The new Yanmars have about 10% more Hp in the same engine size, and might be making back lost ground.

I am not suggesting anybody wait on the 3020s. They may be delayed. They may be nothing like the specs we have gathered. They may not ever come. Nothing is sure until they show up. Even then, they can change.

Maybe when the warranty runs out, I'll see if Gale Banks has a kit to boost the turbo performance on this dude /forums/images/graemlins/wink.gif hehe

Re: New 4x20 series v. mid frame 4000\'s

Anyone have any idea what will happen to the small 4000 10 like the 4110? They don't appear to be represented by the 3000 20 series. Would that indicate that there may be a 2000 20 series in the works? Would the 2210 be in that new series? Just wondering.

My guess is that your guess is a good guess...

Re: New 4x20 series v. mid frame 4000\'s

I suspect Deere will keep the 2210 as is, but as you said, the small chassis be the 2000 Twenty series. One thing I keep hoping Deere will do is make a hoe for the small chassis using the same Rockshaft Assist system that the larger units have. I also hope they bring the eMatch hydro to the small chassis as well as the new design with curved FEL and hoe.. I will probably have to keep hoping, though. /forums/images/graemlins/crazy.gif /forums/images/graemlins/frown.gif
