4310/4410 whats the difference

[mopar]

thanks for the info,i will be talking with mark soon about this at kc canary.i too have seen the misprints in their catalog and it makes me wonder why they don't proof read it?

right or wrong would look at weight and frame size based on what you plan on doing and hp available. 3hp doesn't seem like much but on a 30hp engine thats 10%. Idon't know all that goes into figuring the different ratings for draw hp, pto hp, but hpmakes power. this said I would think you would want the most hp avalible for the size tractoryou were buying.i.e.4410or 4710.

Thanks for the link Bob. I saw while browsing the JD brochure that in fact it does post the torque for the 4410 as higher then the 4510 or 4610 at rated speed which is the maximum engine RPM or 2600 RPM. After thumbing through the catalogs from JD, I thought the products they offer are great. For my needs, I think I will be looking at the 4610 or 4710. I would choose the 4410 if it came with the 460 loader which has a considerable lifting advantage over the 430, over 1000lbs at the pins. Those would roughly compare to the Kubotas L3830 and the 4330. I was wondering about two things JD offers

1. Has is the eHydro
2. How does Load Match work? I see what it does, but how does it do it?

Yep....this is the same information supplied me by my dealer. Spec sheets do say the 4410 has higher torque than the 4510 or 4610. It's hard to believe JD's engineers would get this wrong. If it's a misprint caused by JD's marketing division, why haven't they picked up on it and corrected the misprint as I've seen this info on a couple different pieces of JD literature?

<font color="blue">"...For my needs, I think I will be looking at the 4610 or 4710..."</font>

You'll like either one....but as discussed in the aforementioned posts the 4710 does have the highest torque ratings in the 4x10 series if power is what you're looking for. If interested, take a look at my 4710 in the thread entitled New 4710 Came Home Yesterday in JD's Owner/Operating Forum. You'll have to scroll back to last July or thereabouts. I could not be more pleased with this unit's operational performance. It's quite a dynamo that's packed into a compact tractor frame.

<font color="blue">"...How is the eHydro..."</font>

eHydro runs great. I had some hesitancy when I bought the 4710 when I heard they changed the 4700's HST to the eHydro. HST would provide a more abrupt stop when foot is released from forward pedal....I heard from others though eHydro provided more of a rolling stop with a greater tendency for the operator wanting to brake. I have not experienced this. On level terrain, eHydro will come to a rolling stop without braking within a reasonable distance.

<font color="blue">"...How does Load Match work? I see what it does, but how does it do it?"</font>

To be frank....I really don't know. /forums/images/graemlins/tongue.gif I've never had a reason to use it. I've picked up some fairly heavy loads of fieldstone with proper ballasting on the 3PH and I've never experienced difficulty with lifting the load or transporting it to the degree I needed to use Load Match.

(in your best Elmer Fudd voice...)

...Be very very careful when reading JD printed material...

In my "research" while trying to pick a tractor, I've found dozens of typos, misprints and inconsistent information in printed JD information - from promotional brochures right through into the owner's manuals.

(I actually ordered JD and NH owner's manuals to gain further insight into the "real-world" differences. Maybe a bit over the top, but it actually was very helpful.)

I was always /forums/images/graemlins/confused.gif on the oft-quoted torque rankings (of the 4410) - the info posted by John Miller makes more sense. And if you do the math converting hp and rpm to torque - something just isn't right in the "common" 4410 ranking compared to the 4510/4610. Peak torque is another matter and I wish that number was easier to find for all the models.

I think the possibility exists that at rated speed (2600 RPM) it is quite possible that the torque is higher on the 4410 vs the 4510/4610 engines. I would like to see a graph of it, but as Mr Miller pointed out, the peak torque on the 4510/4610 engines exceeds that of the 4410. While looking at the graphs for another tractor brand, it is apparent that they share a commonality, high torque rise with peak torque typically around 1500 RPM. As maximum engine rated speed is approached, that curve drops quickly. My experience with compact tractors is that the little diesels in them do a very good job considering what it is they are required to do. Rat...

Yep....that's exactly what those charts in that publication I posted illustrate.

Hi MaRK... /forums/images/graemlins/wink.gif

First off... my Father and Grandfather don't visit TBN... /forums/images/graemlins/smile.gif
...so save the "Mr. Miller" for them... /forums/images/graemlins/blush.gif

Now Mr. Ratermann, ...on to some more serious business... /forums/images/graemlins/shocked.gif

I have made different spreadsheets on Yanmars (& Kubota's & Perkins, etc.) that are kinda in a state of disarray right now... but you asked and you shall receive... /forums/images/graemlins/tongue.gif

(next post)...

Sorry John, its a habit when speaking to such knowledgeable and respectful folks.


You have a knack for obtaining information, did you work with the CIA? You never cease to surprise me, Thanks, Rat.
