Auxiliary fuel tanks on Deere tractors.

rockyridgefarm · Feb 5, 2021

This will start sumptin...

I read somewhere that Auxiliary fuel tanks tended to be popular back in the day on big Deeres because the engineers intended for them to work a ten hour day. Not a good plan for most because the tractors were so comfortable and nice to drive that drivers wanted to stay out twice as long. You seldom see them on other brands because at the end of a ten hour day, the driver was more than willing to quit!

Don't know about that. There were a few around here, mostly with guys that were spread out pretty
good and weren't close to the fuel barrel all of the time. Added front weight was an advantage.

Or they used more fuel than the other
brands lol.

Maybe a 4020 was a big tractor in its day, but it certainly wasn't considered big by the time I got it. When it was my main tractor I was annoyed that it wouldn't go a day without refueling. So even it could have benefitted from more fuel capacity. I couldn't add anything to the front as I had an old loader on it for picking stone.

i had one on my 4440 and 4450 john deere,both made it so i could run thru the day on the planter, they were on both tractors when i bought

My JD 4255 will pull my 467 rd baler for about 18-19 hrs utilizing only factory 65 gallon tank

If you had a case tractor you wouldn't need the extra tank
because you would get the work done before the tank went
empty.and dinner got cold.

In 1968 my ex-father-in-law bought 2 4020 diesels, one for him and one for his son. I was just starting farming and had a used 1964 JI Case
930 Western Special. I went with my 5 btm plow to help with fall plowing. Both JDs had 5 btm plows. At noon both 4020s would go home for fuel
and my 930 stayed in the field. They would gripe about me coming up from behind and bumping their plow tail wheel...true story. Plowed the
same depth and faster and used less fuel.

Did it use less fuel you think or the case had a bigger fuel tank. My uncle on his would not go up to fuEl an it pulled a 5 bottom. Lots of times when my cousin got off the bus he had to go out and plow. It mess out what we had planed to do lol.

According to tractor data the case has a 48 gallon tank the my 4020 holds 30 of course tractor data can’t be trusted when it says something bad about anything but John Deere

There have been plenty of Deeres without enough fuel capacity... from the G that would need gas in the afternoon, to
the 4240 that could run 6-7 hours before a fill, there have been quite a few that needed a mid-day drink. Some of
ours that didn't- the 5020 could run a long time on a fill, which was handy when we used it on the forage bagger or
blower. The 720 could run for what seemed days on a tank, especially if doing light duty.

The old way of thinking was enough fuel for a ten hour day. Maybe Deere did not have enough room in front for a bigger tank without a major design change. I think that small tank was the main reason for the rumor about Deeres being so thirsty. My red blooded brother in law used to use his 1086 and 5-16 plow to help out his uncle plow. His uncle had a 4440 pulling a 5-16 Deere plow. To this day my brother in law claims the 4440 used so much more fuel than the 1086 because his uncle was running home for fuel more often. The 1086 held 80 gallons where the 4440 held 60 something. I told him to look it up on the Nebraska tractor test site and compare the two in a scientific calculated test environment. The 4440 was 1/4 of one horsepower hour per gallon more thirsty than the 1086. That is within the margin of error. His response to that data was; WELL DEERE PAID THEM OFF TO MAKE THE 4440 LOOK BETTER!!! Sometimes we just have to change the subject. According to Nebraska my 4650 is more fuel efficient than his 1086 but I am not going to bring up the subject again.

I have seen that myself. I've made the offer for anyone with a 4020 to bring their tractor and 6-16 plow or 10 shank chisel to my place and go in the field with my 1030. If I don't do more work on less fuel I'll pay transportation costs both ways. Or I'll bring my stuff to your house if you pay my way if I lose. The later 4020 was supposed to be rated 100 hp. So far no one has taken me up. I would even let them turbo the 4020 or bring a 4320 as long as the engines are stock.

And today's big tractors hold ~300 gal.
Which you can still blow through in 10
hours if you're working hard.

tomstractorsandtoys · Feb 5, 2021

Jon the first 4020's were 91 hp and then upgraded to 95 on the syncro range tractors. Tom

casecollectorsc · Feb 5, 2021

It had a bigger tank but also had a meter on his tank. My 930 used less fuel per hour than either 4020. Mine used right at 5 gph and the 4020s were 5.8 and 6 gph...plus I was running faster.

casecollectorsc · Feb 5, 2021

A friend says they hold 35 gallons....

jon f mn · Feb 5, 2021

Tractor data calls them 95/97. Which is irrelevant since I freely say that on a dyno a decent one will put out more hp than a 930 and most 1030s. But my offer to work a field side by side with a 6-16 plow or 10 shank chisel behind my 1030 rated at 101 against a 4020, with or without turbo or a 4320 still stands. I would make the same offer with a 930 if I had one.
