John Deere 4020 Turbod

BarryRanch · Feb 15, 2015

So I'm looking at maybe getting a 4020 Powershift. The only problem is I'm at 5000ft above sea leval so I'd needa turbo it. What do you guys recomend? Or am I better off going with a 4430? Thanks

Not a concern to worry about.

As in turboing a 4020?

Power loss at 5000ft with a 4020 is of little to no concern. What is the intended use? Hours per year, primary tractor to make a living, 2nd tractor for the busy season or hobby use?

Well a third tractor. Something thats not dualed up ya know? Mostly a grinder and dry fertilizer spreader and other odd stuff heavy brush cutting will be a main use. Hours a year will vary depending on what else we use it for, but I'm guessing around 400-500 hrs maybe less.

I have a 4020 powershift with a 4430 manifold and
turbo and it's a good tractor.

The hood has to be altered correct? How much hp does it put out?

Why not just find a 4520?

Its a good idea, but the powershifts are getting harder to come
by for under 12 grand. The 1000 only really hurts it, but I could
throw all the 540 shafts away and never miss them.

I've seen rough estimates of around 3 percent power loss per 1000 foot of elevation for naturally aspirated engines. At 5000 foot you could be down 15 percent compared to at sea level due to the lower barometric pressure at higher altitudes. You should verify this at one of your local shops.

If you don't need the extra power, you could dial down the maximum fuel setting to avoid wasting fuel (black exhaust smoke). Some folks like to see black smoke from a diesel and prefer to over-fuel them.

Many modern fuel injected engines have barometric pressure sensors and automatically adjust fuel delivery for changes in barometric pressure.

I'd look for a 4320 that's the factory turbo version of the 4020.

And if I do need the extra power? What do you recomend? Thanks

The only problem is a 4320 isn't powershift. On a brushhog cutting heavy brush I need to be able to drop a gear so I don't stall it. Just easier on the motor ya know?

ss55 · Feb 16, 2015

If you do need the extra power then your original idea of a turbocharged tractor is a good solution.

Grab the PS lever and select one gear lower.

Air at 5000ft has 86.2% of the density of 0 ft. 73.9% at 10,000ft. 62.9% at 15,000ft.

Just for the sake of conversation. Over 50,000 people live in the mountainous city of La Rinconada Peru located in the Peruvian Andes. At an altitude of 16,732 feet.
They must be a robust bunch. Most people would die if taken to that elevation.

If you are talking side counsel 69/72 4020 turboing wont be a problem if used correctly.You can buy a 4430 with a good cab for same money and an extra $5K will get you a 4440.Most turboed 4020s are set at 125H.P.which is a little less than 4430.The turbo charger wont hurt anything but wrong operator sure can.
