John Deere 4320 powershiftless

BarryRanch · Mar 21, 2015

Can someone explain to me why the 4320 didn't have a powershift? I know some guys say its cause "they weren't made that long and they already were coming out with the 4030 series." Well, I find that a bunch of crap cause they gave the 4000, 4520, and 4620 a powershift option. So why not the 4320? I mean, a 4520s powershift tranny would bolt right up to the 4320, correct?

Let's round up the remaining 70+ year old Deere managers, accountants and engineers . Then flog the rotten b-----ds for not offering a PS in the 4320. Or you could just go and find yourself a 4430 .

How do you know a 4520 tranny will bolt up to a 4320? 4520/4620s used parts similar to the 5020 syncro tranny. The powershift was the same design as the 4020 powershift but everything was bigger. I've heard it would be easier to bolt a 4020 tranny up to a 4320. But then it probably wouldn't withstand the hp. And secondly, it wasn't difficult to add the powershift tranny option to the 4000 since they are a minimum spec'ed 4020. If you actually read about them, it does sound like JD would have to make a new tranny just to fit the 4320 that like you said would be in production for 2 years or less.

It is probably is as simple as the 30 series was on the way.

Remember, the 4520 was introduced in 1969, 4 years before the 30 series. THe 4620 was an improved 4520 (added intercooler, altered air cleaner, new number as the 4520 got a REAL bad wrap real fast). The 4620 PS required no new parts that weren't already designed.

The 4000 was the same... it was essentially a 4020 lightened up.

The 4320 was a design that required some new parts... the dash etc would have needed to be redesigned to accomodate the PS transmission., as those components are not the same as a 4020.

The 4320 was introduced in 71, with an engine very similar to the 4520 of two years prior.

Looking at production numbers in the early 70s, syncro usually out sold PS by two to one, perhaps closer to 3 to one. I can understand why a horse to be in the line for 2 years or less wouldn't get the option.

Consider this, too- Deere had a PS in a scraper tractor that used a 531 engine. Yet there is no PS 5020 or 6030. The 4320 wasn't alone.

And I am not certain, but I don't think there were PS 4030s either. The PS from a 3020 probably would've worked...

4520 would probably bolt to a 4320 because they both used the 404 engine, 5020 used a 531.

A 4520 is a much heavier transmission and rear end than a 4320...two total different tractors from the engine back

I thought it was one of Buick's best posts EVER!

('Course I don't like revisionist history, or fantasy football, either!)

Powershifts rob horsepower and 5020s needed all the hp they can get. The 5020 was wheatland type tractor that you typically left in one gear all day long anyway. And on the scraper part, the 760A which used the 531 only went up to 160 hp. Doubt the tranny would have stood up to 200+ in the 6030. And this is just my opinion, I think JD was trying to keep the cost down too. I have some cousins with 6030s and talking to them and other guys from back then when 6030s were new, they were a horribly expensive tractor to buy.

I actually chuckled at it a little!

In 1971-72 was there much demand for a 4320 with PowerShift? 4020 PS and 4620 PS were close alternatives if you needed PowerShift.

BarryRanch · Mar 22, 2015

You're right, I've never ever scene a 4030 with powershift. But just cause I've never scene it, doesn't mean there isn't some out there.

BarryRanch · Mar 22, 2015

I agree lol.

GreenEnvy · Mar 22, 2015

As of 1974 the only tranny options for the 4030 was the syncro, quad, and the creeper. No powershift. Straight out of a 1974 brochure.
