4020 with combine engine ???

jeremy in NE · Jan 25, 2015

Going to look at a late model 4020 that has had a combine engine
put in and I have a few questions. Did the motor have the same
power and torque curves. It appears to be a 30 series style motor.
I had my brother look at it and it started right up at 35 degress with
no either or being plugged in. Anything to look for? Thanks

It depends on what combine engine went in... if it was a non turbo 404, it would be very similar. If it has a turbo, or is a 466, then it will be different- more power in either case.

Have been around a couple like that and both were very strong runners. It can be a tough sell though, because most guys would rather have the original motor. If it doesn't turn you off, I'd think you'd be able to get him down to where you want to be on it.

So if a combine engine can be put in a 4020 is there an engine that can be put in a 3020 diesel? I've got one with a busted rod and who else knows what, maybe it'd be easier to do an engine swap than an overhaul.?

3020's had orphan engines. Not many other applications than 3020. Bell housing is different than the 300 series engine that were built in Dubuque/Mannheim/Saran.

It does not have a turbo. How can I tell between a 404 and 466? I will probably never get rid of it if I buy it. It will be a general purpose tractor not a tillage tractor. Thanks

I bought an estate 4320 that had a combine motor and I actually would not have known except oil filter was Horizontal instead of vertical.There were certain 404 that were near identical I believe in 6600 combines.As for value it doesn't add but most combines are much lower houred than tractors and some are rated higher in power.There are ways to do it right like Tim S.has stated and I have also seen some with added frames which would hurt.Repowers happen and I had a near perfect 2520 gas that had a 239 diesel and the serial number and of course side panels were about the only signs.It was a lot cheaper than if it was original and probably better.

466 will have the oil cooler similar to photo on LH side of block 404 won't.Serial number plate will show.

Are you sure on this Jim? I looked up a 6600 and it shows that same oil cooler. The 30 series tractor 404 also has it.

Visually comparing the later 404 to the 466, it is very difficult to tell them apart if they are equipped the same. Look at a 4630 vs a 4640. They are very similar.

If someone used a 466 on a 4020, it would likely still have it's inline pump. But more than likely it is not a 466 as it was very common to put 6600 404T or non T motors in them. You could even do away with the turbo if you wanted to. The 6600 had a rotary pump but it was noticebly different from the 4020 pump and would be at the front of the engine like a 4320/4620. Best thing is if the eng. serial plate is intact.

But yes the combine motors typically have a lot less hours on them. If somone posts up the hp and torque numbers for a 6600, I guarantee they will be higher than a 4020.

coonie minnie · Jan 25, 2015

Jim,

The later 404s, like in a 4230, had the oil cooler
as pictured, too.

You are correct that the serial number would be
the best ID!

coonie minnie · Jan 25, 2015

You are correct in that the tag is the best place
to look... I have a non-turbo 466 that is in our
4020. We had it put in new in 89. It has a
rotary pump, and very difficult to tell from, say,
a 4230 (or 6600, or 4040) 404 engine.

That said, those natural 466s are not all that
common from combines. I believe only the small
engined 6620s had them.

Mikein Ky · Jan 25, 2015

There was a guy on here last winter that put a 404
in a 3020. 3020 has the same bellhousing pattern as
4020. He lengthened the hood and hydraulic lines.
It really came out pretty good. I might try it if I
found a 3020 with a bad engine. I put a 4430 engine
in my 4020 gas with some advice from TimS. It made
a nice tractor too.

DAVISFARMS · Jan 25, 2015

In as far as I am concerned if it is not a 1972 4020 who cares but the enscure don't change notihn folks .I have a 4230 with a combine engine I put in and unless you were told you wont never know...

Thanks for correcting my mistake on the oil cooler. Danged oldtimers disease.

Heard of 3020 repower w/ford 4cyl turbo diesel out of delivery van and Cummins engs.

larryanderson · Jan 25, 2015

Davis Farms I would agree if done correctly it wont affect value in a using tractor.There have been many JDs that were updated such as 4520to 4620 motor and 30/40/to50 series engines.The Kinze conversions still bring a premium.I have dealt with a few serious collectors and that is entirely different.

johnwayne360 · Jan 25, 2015

I have read(but never seen) that you can put an
engine out of a 2750 in a 3020 fairly easily. Im sure
someone will let me know if its not true..lol..

tim s · Jan 25, 2015

Yes Some one in Indiana I think was making a kit to do that, But I have never seen one,I have never tried to re-power a 3020,,

DAVISFARMS · Jan 25, 2015

I agrere but a run of the mill 4020 1964 to 68 maybe even later to like 71 who would care,serious collector wont be looking for regular 4020 until 1972 or late late 71 ps or utility high crop any year

DAVISFARMS · Jan 25, 2015

saw 1 down here tim had 404 in it

I saw a copy on the interwebs somewhere of a Deere re power program for 3010/3020's from back in the late 70 possibly early 80's where they were putting a brand new 239 or 276 in place of the old engine, came complete with a modified set of frame rails and everything needed. You of course had to send you frame rails back as a core.

johnwayne360 · Jan 25, 2015

just googled 3020 repower. Guy in wisconsin in farmshow magazine. 6900 bucks plus your core for trade..ouch..

tim s · Jan 25, 2015

I never heard of that program...would like to know more..

jeremy in NE · Jan 25, 2015

Thanks for all the info. It does have the oil cooler on the side of the block. Where is the serial tag on these?

coonie minnie · Jan 25, 2015

Superior Diesel of Rhinelander WI (a Deere engine distributor) offered these kits. Our 466 for the 4020 came through them.

There was a converted 3010 or 20 at the WI Farm Progress Days at least once, and I remember a 4020 with a 414 too. Both were displayed by Superior, and not the Deere booth.

Cliff Nelson seemed to have some experience with this. I have not seen one since the farm shows, however.

With the shortage of good 3020 blocks, cranks, etc. this would be valuable info to have today.

Horse Feathers. How pray tell are you bolting a Dubuque four cylinder into a Waterloo Bell housing bolt pattern, front mounts and pump drive?
The 2510,2520,4030 and late 4050's had a Dubuque in a Waterloo chassis .

Ben So Tex · Jan 26, 2015

My brother put a 95 diesel combine engine about 10 years ago in 4020 and it is running good today

Richard in Bee · Jan 26, 2015

Eight hours huh?

larryanderson · Jan 26, 2015

The 3020 conversion looks nice .I wonder what the cost is.I have heard of some late 3020s sitting for lack of engine.Looks like H.P.would be close and to do a complete swap in 8 hours means no fabricating.

FarmerCline · Jan 26, 2015

It looks like John Deere made a printing mistake on that 3020 repower brochure. It says to replace the original 270 gas and 270 Diesel engines but the 3020 gas engine was a 227(early) or 241(late). I wonder if many 3020 gas tractors were switched over to diesel with that repower engine?

4020 with combine engine ???
