4320 vs 4720

[Spudland_Dave]

One item for thought about the tractors. We have seen the HP discussions. In large scale manufacturing it is not uncommon to have several different models with common theme. While they appear identical, the "lower" models may be constructed with lighter strenght/ weight components, or those that could not pass (by lot testing) the higher power levels. I wonder if any of that is at work with Deere? Common spare parts cannot be used to deny this as it makes sense to stock the parts with the highest rating to reduce required inventory.

While what you say is very true in some markets/products...on something like Deere tractors (small production numbers when compared to a F150 for example) I would doubt there is any financial incentive for Deere to use "lighter duty" parts. By using a lighter duty part/different spec part it reduces their buying power that much more...further seperate the High & Low end of the 4x20 series and you now need to source a smaller quantity of light duty parts, and a smaller quantity of heavy duty parts. It would be cheaper for everybody...engineering, purchasing, manufacturing, shipping, assembly, Service parts, etc.. to just pool the resources and purchase one super large batch of part XYZ.

This is what I went to school for and back 10 years ago and still to this day, 98% of the time, when you factor everything in...its cheaper to use something exsiting rather then "re-engineer the wheel"

Is 6hp and 7% flow all you get for $3.6K?
Are there ANY other differences?

I think that the 3520 - 3720 upgrade provides 7hp and deluxe seat option for $220 less; what am I missing?

I'm not sure I understand where you're coming from with the 35-3720 and the 43-4720 comparisons. (Maybe it's some confusion between a 4320 or a 4520 upgrade to a 4720...).

When I go through the math on the Deere site - upgrading to a 3720 (from a 3520) costs more than upgrading to a 4720 (from a 4520).

The difference between a 4320 and the 4720 is likely ~$3.6K, BUT the Hp difference is NOT 6 Hp - it's 18 Hp.

I guess I was confusing by being too brief.
Although Laird006 was interested in the difference between 4320 and 4720, I was trying to show that he should consider the 4520 as it has everything the 4720 has except for 6 hp. (and possible 7% flow) for 3.6k less.
I then asked if anyone else could discern any other differences between 4520 and 4720.
It seems to me that there are differences in the 3000 series, such as intercoolers and cab options, possibly others, when comparing the 3520 to the 3720.
My math was off by thirty dollars 250 vice 220.

4520 28,999 - 60hp
4720 32,629 - 66hp
differ 3,630 - 6

3520 21,419 - 37hp
3720 24,799 - 44hp
differ 3,380 - 7

250 upgrade difference

Need to be careful to compare "apples to apples"... The 3520 and the 4520 are configured with the power-reverser tranny - not the eHydro - that comes as a standard feature on the 3720 and the 4720.

Maybe that's why most folk's quote the "around $2K" difference when discussing the upgrade from the 5's to the 7's.

Alot depends on options too. I know that when I was buying last year the difference in price between the 4520 cab and 4720 cab was around $3000. I decided to go with the 4520 cab with full weights front and rear, 3rd rear outlet, telescopic links, rear wiper, economy pto, rear work lights, upgraded cruise, R4 tires, hood guard and I Match for $34,000. For the $3000 difference I bought the 673 tiller.

I just received my new 4320 yesterday, and AK fish is correct. The hydraulic flows are the same for the 41XX series according to the booklet I took from the dealer.

Congratulations Very nice!
The 'testing' seems to be going very well!

I think it was about $2200 when I was looking at it (3520 Deluxe CAB vs. 3720 Deluxe CAB).

Congratulations on your new tractor!! You'll have to post a new thread with some added pics and the details of your DEAL!

(I've got a wife that wants a round-pen, too....) Always somethin'!

oh yeah, CONGRATS on the Big Green Purchase

The 4720 is definitely worth the difference in cost there v. a 4320. For bush hogging and heavy PTO work the difference would be noticeable. For loader work and ground engagement only, not so much. If I had gotten two prices quoted that close I would not be looking at the 4320. One must think amortized over the life of the tractor, which can and hopefully will be several thousand hours, this difference in cost is nominal. In addition, a 4720 on the lot used or in Craig's List, whatever, is a hot commodity. While they might not resale any better, I can tell you they would garner more attention and interest than a 4320--thus they might have a better resale value in the event of sale.

Trust me, as someone who has learned this the hard way, the first time someone encounters something a 4320 won't do well, he will say,"I should have gotten a 4720" and will loathe the day he did not pay a couple thousand more to do so. If one has the same thought about the 4720, then it was time to move into a larger tractor anyway which would have likely meant more upfront cost difference and potential compromises. Go 4720 and do not look back. You will not regret having paid additional pittance for the extra power over time.

I had a open station 4720 and I replaced it with the 4520 cab.

I found I was not using the power and it was over $2K difference.

Now, one thing that was not clear to me was that the air ride seat is included in the 4720. So, if you want that - it eats up part of that difference in a hurry.

It is hard to get the power to the ground now with the 4520 even with the extra wheels weights, etc.

I suspect with what I am doing with my 4520 a 4320 would work fine.

Interesting specs to say the least. Both are turbo, same CI displacement,CR, same rpm operating range. One can only summize to get a difference of 17 hp ( 56 pto vs 39 pto ) they need more than larger fuel injectors ( 3/4 gallon per hour difference ). How would the dealer explain this ? For only 3k difference it would be a no brainer to get the 4720.

I used to think it was a no brainer, but the reality is I won't use all the power anyway. So, having $3K sitting in some thing I don't need - I went with the 4520.

The only time I hear the turbo even kick in is when I am punching post holes.

The platform is somewhat small - weight and size wise. So getting the power to the ground can be an issue.

Also - it is somewhat of a hassle to use larger implements. Like I have a HX-15 15' batwing. I believe the mower weighs more than the tractor. Also, it requires 2 rear valves - I have one. I don't think I would want to pull that mower anyway - it is a hoss.

I guess the punch line - size up what you plan on doing and get the right tractor. Higher HP is not always required.

I have almost 200 hours on my 4520 and 775 on my 5525. When I sold my 4720 it had 250 or so.

I have had a 4120 for the last (5) years and have never felt a need for more power. I can actually move dirt faster, using the bucket, with my tractor than my nieghbor can with his 4720. This is simply because my R1 tires are loaded and his R4's are not, making it much easier for me to get power into the ground, and both our machines have identical hydraulic output. I am sure glad I didn't waste any of my hard-earned dollars on all that excess hp. Those of you with money to burn may as well go for it and get the 4720.

"I have had a 4120 for the last (5) years and have never felt a need for more power."

I feel better about purchasing the bottom rung in the ladder already LOL!

 

[ddivinia]

I looked at it as they are all 4wd and the hydraulics are the same. The only deal was I had to have e-hydro and a cab. I think all the 4x20s are good tractors.

[jenkinsph]

I agree that my 4520 cab with 50 pto hp has plenty of power for this frame size. If you need more power you should consider moving up to a larger frame size, more weight and larger tires.

For a nice compact tractor I think the 4x20 tractors are hard to beat. Really like the ehydro transmission which I think is a perfect match for my 110tlb and 4520.

I agree 100%. Exactly why I have a 5525. I have to say if they put a e-hydro in a larger tractor I bet my wife goes for it. She likes the ride of the 5525 way better than the 4520. Heavier, long wheel base, etc.

I could envision a IVT transmission in 5000 series in a few years. That would be getting close to a HST but still the power of a geared tractor.
