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'!
